We completed the initial public offering of 12,000,000 ADSs, each representing five ordinary shares on December 26, 2006. On December 20, 2006, we listed our ADSs on the Nasdaq Global Market, which are traded under the symbol “HSOL.”

On January 29, 2008, we closed an offering of US$172.5 million 3.50% convertible senior notes due 2018, or 2018 convertible bonds, to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended, or the Securities Act, and received net proceeds of US$167.9 million. Concurrently with this convertible bond offering, we closed an offering of 9,019,611 ADSs, representing 45,098,055 ordinary shares, to facilitate the convertible bond offering. We did not receive any proceeds, other than the par value of the ADSs, from such offering of ADSs.

From July 17, 2008 to August 12, 2008, we issued and sold 5,421,093 ADSs with an aggregate sale price of US$73.9 million.

From September 17, 2009 to November 18, 2009, we issued and sold 3,888,399 ADSs with an aggregate sale price of US$23.1 million.

In September 2010, we issued and sold to Hanwha Solar Holdings Co., Ltd., or Hanwha Solar, 36,455,089 ordinary shares for an aggregate sale price of US$78.2 million. Concurrently with the closing of this offering, we issued 30,672,689 ordinary shares to Hanwha Solar at par value of the ordinary shares and subsequently an additional 14,407,330 ordinary shares at par value, which shares shall remain outstanding so long as and to the extent that the 9,019,611 ADSs we issued to facilitate our convertible bond offering in January 2008 remain outstanding. At the same time, Hanwha Solar completed the acquisitions from Good Energies II LP and Yonghua Solar Power Investment Holding Ltd., the company owned by Mr. Yonghua Lu, our former chairman, of a total of 120,407,700 ordinary shares and 1,281,011 ADSs of our company, representing all of the ordinary shares and ADSs held by them.

Risks Related to Our Company and Our Industry

Demand for our PV products has been, and may continue to be, adversely affected by volatile market and industry trends.

Demand for our PV products has been affected by global economic conditions, capital markets fluctuations and credit disruptions. During the second half of 2008 and the first half of 2009, many of our key markets, including Germany, Spain and the United States, and other national economies experienced a period of economic contraction or significantly slower economic growth. The global financial crisis, weak consumer confidence and diminished consumer and business spending have contributed to a significant slowdown in the market demand for PV products due to decreased energy requirements. In addition, many of our customers and many end-users of our PV products depend on debt financing to fund the initial capital expenditure required to purchase our PV products. During the global credit crisis, many of our customers and many end-users of our PV products experienced difficulties in obtaining financing, and even if they were able to obtain financing, the cost of such financing had increased such that they changed their decision or changed the timing of their decision to purchase our PV products. There can be no assurance that our customers or end-users will be able to obtain financing on a timely basis or on reasonable terms, which could have a negative impact on their demand for our products. Rising interest rates may make it difficult for end-users to finance the cost of PV systems and therefore reduce the demand for our PV products and/or lead to a reduction in the average selling price of our PV products. Since 2010, we have experienced an increase in demand for our PV products due to the economic recovery and the shortage of manufacturing capacity in the industry. However, we cannot provide assurance that such increase in demand will continue in 2011. A protracted disruption in the ability of our customers to obtain financing, economic downturn or an increase in manufacturing capacity of the PV industry could lead to a significant reduction in future orders for our PV products, which in turn could have a material adverse effect on our business, financial condition and results of operations. In addition, since we have substantially increased our production capacity in the past few years, the decrease in demand for our products may lead to idle capacity. If the reduction in demand results in significant amount of our capacity not utilized, our assets may be impaired.

The average selling price of our PV products may continue to decrease.

Beginning in the fourth quarter of 2008, the supply of PV products has increased significantly as many manufacturers of PV products worldwide, including our company, have engaged in significant production capacity expansion in recent years. As a result, this state of over-supply has resulted in reductions in the prevailing market prices of PV products as manufacturers have reduced their average selling prices in an attempt to obtain sales. The average selling price of our PV modules per watt decreased from RMB26.77 in 2008 to RMB15.27 in 2009, and to RMB11.58 (US$1.75) in 2010. Our net profit margin increased from a negative margin of 5.7% in 2008 to a negative margin of 3.8% in 2009, and increased to a positive margin of 10.1% in 2010. The average selling prices of our PV products may decline further, which could cause our sales and/or our profit margins to decline and have a material adverse effect on our business, financial condition, results of operations and prospects.

As silicon supply increases, the corresponding increase in the global supply of PV modules may adversely affect our ability to increase or maintain our market share.

Silicon is an essential raw material used in the production of solar cells and modules. Prior to mid-2008, there was an industry-wide shortage of silicon. Increases in the price of silicon have in the past increased our production costs, and any significant price increase in the future may adversely impact our business and results of operations. Due to the historical scarcity of silicon, supply chain management and financial strength were the key barriers to entry. In late 2008 and 2009, however, newly available silicon capacity has resulted in an increased supply of silicon, which resulted in downward pressure on the price of silicon. However, we cannot assure you that the price of silicon will continue to decline or remain at its current levels, especially if the global solar power market regains its growth momentum. As the shortage of silicon eases, industry barriers to entry become less significant and the PV market may become more competitive. If we fail to compete successfully, our business may suffer and we may lose or be unable to gain market share and our financial condition and results of operations may be materially and adversely affected. Such price reductions could have a negative impact on our revenues and net income, and materially and adversely affect our business and results of operations.

The reduction or elimination of government subsidies and economic incentives for on-grid solar energy applications could have a material adverse effect on our business and prospects.

We believe that the near-term growth of the market for “on-grid” applications, where solar energy is used to supplement a customer’s electricity purchased from the electric utility, depends in large part on the availability and size of government subsidies and economic incentives. The on-grid market, the reduction or elimination of government subsidies and economic incentives may hinder the growth of this market, which could decrease demand for our products and reduce our revenue.

The cost of solar energy currently exceeds the cost of power furnished by the electric utility grid in many countries. As a result, federal, state and local governmental bodies in many countries, most notably Germany, Spain, Italy, the United States, Australia, Korea, France and the Czech Republic, have provided subsidies and economic incentives in the form of rebates, tax credits and other incentives to end users, distributors, system integrators and manufacturers of PV products to promote the use of solar energy in on-grid applications and to reduce dependency on other forms of energy. Certain of these government economic incentives are set to be reduced and may be reduced further, or eliminated. For instance, in 2009, the German government reduced solar feed-in tariffs by 9% and in July 2010, reduced feed-in tariffs for rooftop installations, ground-mounted installations on commercial land and ground-mounted installations on converted land by 13%, 12% and 8%, respectively. Beginning in October 2010, each category of feed-in tariff will be reduced by a further 3%. Installations on agricultural land are ineligible for incentives. In 2008, 2009 and 2010, Germany accounted for 53.3%, 70.6% and 62.5% of our net revenues, respectively. In May 2011, the Italian government approved a decree to cut incentives for solar projects. The decree introduced a subsidy spending cap on large projects from 2011 to 2013 and a gradual reduction on feed-in tariffs starting June 2011.

In addition, political changes in a particular country could result in significant reductions or eliminations of subsidies or economic incentives. Electric utility companies that have significant political lobbying powers may also seek changes in the relevant legislation in their markets that may adversely affect the development and commercial acceptance of solar energy. The reduction or elimination of government subsidies and economic incentives for on-grid solar energy applications, especially those in our target markets, could cause demand for our products and our net revenues to decline, and have a material adverse effect on our business, financial condition, results of operations and prospects.

Our ability to adjust our raw material costs may be limited as a result of our entering into multi-year supply agreements with many of our silicon and silicon wafer suppliers, and it may be difficult for us to respond in a timely manner to rapidly changing market conditions, which could materially and adversely affect our cost of revenues and profitability.

Prior to mid-2008, there was an industry-wide shortage of silicon-related materials including silicon, silicon wafers and PV cells, which resulted in significant increases in the prices of these raw materials. To secure an adequate and timely supply of silicon-related materials during the earlier periods of supply shortage, we entered into a number of multi-year supply agreements. The prices in the agreements we entered into prior to mid-2008 were generally pre-determined, but some of these agreements provided for adjustments in subsequent years to reflect changes in market conditions or through mutual agreement. Since the fourth quarter of 2008, the market prices for silicon-related materials have been decreasing significantly. Spot market prices of silicon-related materials have fallen below the prices we have contracted for with our long-term suppliers and continued to decline in 2009. Due to the significant decrease in prices of silicon-related materials, we re-negotiated all of our multi-year supply agreements that were in place as of December 31, 2009, except the agreement with Jiangxi LDK Solar Hi-Tech Co., Ltd, or LDK. After re-negotiation, the pricing terms of such multi-year agreements were generally subject to review either periodically or upon significant changes in prices on the spot market. The pricing terms of each of these multi-year agreements were adjusted to be more in line with spot market pricing at the time of the re-negotiation. In addition, the quantity and/or timing of deliveries were also adjusted in each case to reflect our updated purchase requirements as a result of the changes in market conditions and our capacity expansion. Currently, there is only one multi-year supply agreement we entered into in 2010 where the price is pre-determined without any future adjustment. While we have obtained reduced prices and other concessions from our suppliers, we cannot assure you that we will be able to obtain reduced prices from all of our suppliers in the future. If the prices of silicon-related materials continue to decrease in the future and we are unable to re-negotiate the prices of our existing multi-year supply agreements, we may not be able to adjust our materials costs, and our cost of revenues could be materially and adversely affected. In addition, the prices of our non-silicon-related raw materials are also subject to market forces beyond our control. If the prices of these materials increase in the future, our non-silicon-related cost of revenues could be materially and adversely affected.

Furthermore, other PV module manufacturers may be able to purchase silicon-related materials on the spot market at lower prices than those we have contracted for with our suppliers. We will continue to purchase a significant amount of silicon-related materials pursuant to our multi-year supply agreements. In the event we are unable to re-negotiate or fulfill our obligations under our supply agreements, we may be subject to significant inventory build-up and may be required to make further inventory write-downs and provision for these commitments, which could have a material adverse effect on our business, financial condition, results of operations and prospects. If the prices we pay for silicon-related materials are significantly higher than the prices paid by our competitors, our competitive cost advantage of producing modules could decrease. Our inability to reduce a key manufacturing cost to the same degree as our competitors could adversely affect our ability to price our products competitively and our profit margins.

We may be subject to legal, administrative or other proceedings in connection with the multi-year supply agreements we entered into previously and such proceedings can be both costly and time consuming and may significantly divert the efforts and resources of our management personnel.

During the course of renegotiation of some of the multi-year supply agreements we entered into previously, we may be subject to legal, administrative or other proceedings if mutual agreement cannot be reached between us and our suppliers. For example, on June 8, 2009, Jiangxi LDK Solar Hi-Tech Co., Ltd., or LDK, one of our silicon suppliers, submitted an arbitration request to the Shanghai Arbitration Commission alleging that we failed to perform under the terms of a multi-year framework supply agreement, seeking to enforce our performance and claiming monetary relief. Deliveries of silicon under the agreement halted in early 2009 and have not recommenced. We intend to continue to vigorously defend ourselves against the claims brought by LDK and, on July 9, 2009, we submitted an arbitration request to the Shanghai Arbitration Commission requesting that LDK refund the outstanding prepayments of RMB104 million that we made under the contract, plus compensation of RMB35 million from LDK for estimated losses incurred by us as a result of the stoppage of deliveries under the framework supply agreement. There is no assurance that we will be able to successfully defend or resolve such legal or administrative proceedings in the near future or at all. Such legal and administrative proceedings can be both costly and time consuming and may significantly divert the efforts and resources of our management personnel. If there are any adverse judgments, our financial condition, results of operations and liquidity could be materially and adversely affected.

Prepayments we have provided to our silicon and silicon wafer suppliers expose us to the credit risks of such suppliers and may not be recovered, which could in turn have a material adverse effect on our liquidity.

Most of our multi-year supply agreements that we entered into during the earlier periods of supply shortage required us to make prepayments of a portion of the total contract price to our suppliers without receiving collateral for such prepayments. As of December 31, 2008, 2009 and 2010, we had advanced RMB1,145.6 million, RMB979.8 million and RMB1,158.3 million (US$175.5 million), respectively, to our suppliers. In 2008, 2009 and 2010, we recorded a provision of RMB42.0 million, RMB234.7 million and RMB0.1 million (US$18,000), respectively, for doubtful collection of advances to suppliers due to non-performance by some of our suppliers, which resulted in the prepayments we made to these suppliers being categorized as unrecoverable. In the event that we have disputes with any of our suppliers and we are unable to reach an agreement on terms acceptable to us, we may not be able to recover our prepayments made to such suppliers. Most of our claims for prepayments are unsecured claims, which expose us to the credit risks of our suppliers in the event of their insolvency or bankruptcy. Our claims against the defaulting suppliers would rank below those of secured creditors which would undermine our chances of obtaining the return of our prepayments. If such suppliers fail to fulfill their delivery obligations under the contracts or if there is any dispute between us and such suppliers that jeopardizes our ongoing relationship, we may have to record a provision relating to or write down prepayments made to such suppliers, which could materially and adversely affect our financial condition, results of operations and liquidity.

Evaluating our business and prospects may be difficult because of our limited operating history, and our past results may not be indicative of our future performance.

There is limited historical information available about our company upon which you can base your evaluation of our business and prospects. We began operations in August 2004 and shipped our first PV modules and our first PV cells in February 2005 and November 2005, respectively. With the rapid growth of the PV industry prior to the fourth quarter of 2008, our business has grown and evolved at a rapid rate. As a result, our historical operating results may not provide a meaningful basis for evaluating our business, financial performance and prospects and we may not be able to achieve a similar growth rate in future periods. Therefore, you should consider our business and prospects in light of the risks, expenses and challenges that we will face as a company with a relatively short operating history in a competitive industry seeking to develop and manufacture new products in a rapidly growing market, and you should not rely on our past results or our historic rate of growth as an indication of our future performance.

Our future success substantially depends on our ability to manage our production effectively and to reduce our manufacturing costs. Our ability to achieve such goals is subject to a number of risks and uncertainties.

Our future success depends on our ability to manage our production and facilities effectively and to reduce our manufacturing costs. Our efforts to reduce our manufacturing costs include lowering our silicon and auxiliary material costs, improving manufacturing productivity and processes, and improving product quality. If we are unable to achieve these goals, we may be unable to decrease our costs per watt, to maintain our competitive position or to improve our profitability. Our ability to achieve such goals is subject to significant risks and uncertainties, including:

•

our ability to continue to re-negotiate our existing multi-year supply agreements;

•

our ability to maintain our quality level and keep pace with changes in technology;

•

our ability to source various raw materials;

•

our ability to adjust inventory levels to respond to rapidly changing market demand;

•

delays in obtaining or denial of required approvals by relevant government authorities; and

•

diversion of significant management attention and other resources to other matters.

If we are unable to establish or successfully make improvements to our manufacturing facilities or to reduce our manufacturing costs, or if we encounter any of the risks described above, we may be unable to improve our business as planned.

We depend on a limited number of customers and countries for a high percentage of our revenue and the loss of, or a significant reduction in orders from, any of these customers or countries, if not immediately replaced, would significantly reduce our revenue and decrease our profitability.

We currently sell a substantial portion of our PV products to a limited number of customers and countries. Our five largest customers accounted for an aggregate of 53.2%, 65.3% and 51.9% of our net revenues in 2008, 2009 and 2010, respectively. Our largest customer in 2008, 2009 and 2010 accounted for 22.2%, 40.6% and 33.6% of our net revenues of the respective period. Most of our large customers are located in Europe, particularly in Germany, Italy, Portugal and the Czech Republic. In 2008, 2009 and 2010, Germany accounted for 53.3%, 70.6% and 62.5% of our net revenues, respectively. In 2010, Germany, China and Italy are the top three countries in terms of percentage contribution to our net revenues. The loss of sales to any one of these customers or countries would have a significant negative impact on our business. Sales to our customers are mostly made through non-exclusive arrangements. Due to our dependence on a limited number of customers and countries, any one of the following events may cause material fluctuations or declines in our net revenues and have a material adverse effect on our financial condition and results of operations:

•

reduction, delay or cancellation of orders from one or more of our significant customers;

•

selection by one or more of our significant distributor customers of our competitors’ products;

•

loss of one or more of our significant customers and our failure to identify additional or replacement customers;

•

any adverse change in local policies toward solar projects in countries where we receive most orders;

•

any adverse change in the bilateral or multilateral trade relationships between China and the United States or European countries, particularly Germany; and

•

failure of any of our significant customers to make timely payment for our products.

We expect our operating results to continue to depend on sales to a relatively small number of customers or countries for a high percentage of our revenue for the foreseeable future, as well as the ability of these customers to sell PV products that incorporate our PV products.

We enter into framework agreements with many of our customers that set forth our customers’ purchase goals and the general conditions under which our sales are to be made. However, such framework agreements are only binding to the extent a purchase order for a specific amount of our products is issued. In addition, certain key sales terms of the framework agreements may be adjusted from time to time. In addition, we have in the past had to re-negotiate some of our framework agreements due to the disagreements with our customers relating to the volumes, delivery schedules and pricing terms contained in such agreements. However, it may not always be in our best interests to re-negotiate our framework agreements and disagreements on terms may escalate into formal disputes that could cause us to experience order cancellations or harm our reputation.

Furthermore, our customer relationships have been developed over a short period of time. We cannot be certain that these customers will generate significant revenue for us in the future or if these customer relationships will continue to develop. If our relationships with customers do not continue to develop, we may not be able to expand our customer base or maintain or increase our customers and revenue.

Our dependence on a limited number of suppliers for a substantial majority of silicon-related materials may prevent us from delivering our products in a timely manner to our customers in the required quantities, which could result in order cancellations, decreased revenue and loss of market share.

In 2008, 2009 and 2010, our five largest suppliers supplied in the aggregate 42.0%, 51.6% and 40.0%, respectively, of our total silicon and silicon wafer purchases. If we fail to develop or maintain our relationships with these or our other suppliers and we are unable to obtain these materials from alternative sources in a timely manner or on commercially reasonable terms, we may be unable to manufacture our products in a timely manner or at a reasonable cost, or at all, and as a result, we may not be able to deliver our products to our customers in the required quantities, at competitive prices and on acceptable terms of delivery. Problems of this kind could cause us to experience order cancellations, increased manufacturing costs, decreased revenue and loss of market share. In addition, some of our suppliers have a limited operating history and limited financial resources, and the contracts we entered into with these suppliers do not clearly provide for adequate remedies to us in the event any of these suppliers is not able to, or otherwise does not, deliver, in a timely manner or at all, any materials it is contractually obligated to deliver. Some of our major silicon wafer suppliers failed to fully perform on their silicon wafer supply commitments to us due primarily to an industry-wide shortage of silicon and silicon wafers. As a result, we did not receive all of the contractually agreed quantities of silicon wafers from these suppliers. We cannot assure you that we will not experience similar or additional shortfalls of silicon-related materials from our suppliers in the future or that, in the event of such shortfalls, we will be able to find other silicon suppliers to satisfy our production needs. Any disruption in the supply of silicon wafers to us may adversely affect our business, financial condition and results of operations.

Our failure to obtain sufficient quantities of silicon-related materials in a timely manner could disrupt our operations, prevent us from operating at full capacity or limit our ability to expand as planned, which would reduce, and limit the growth of, our manufacturing output and revenue.

We depend on the timely delivery by our suppliers of silicon-related materials in sufficient volumes. Until mid-2008, there was an industry-wide shortage of silicon-related materials. While we do not believe a similar industry-wide shortage of silicon-related materials will re-occur in the short term because of current market conditions and the expansion of silicon and silicon wafer manufacturing capacity in recent years, we cannot assure you that market conditions will not again rapidly change or we will always be able to obtain sufficient quantities of silicon-related materials in a timely manner. We may experience actual shortages of silicon-related materials or late or failed delivery for the following reasons:

•

the terms of our silicon and silicon wafer contracts with, or purchase orders to, our suppliers may be altered or cancelled as a result of our ongoing re-negotiations with them;

•

there are a limited number of silicon and silicon wafer suppliers, and many of our competitors also purchase silicon-related materials from these suppliers and may have longer and stronger relationship with these suppliers than we do;

•

some of our silicon and silicon wafer suppliers do not manufacture silicon themselves, but instead purchase their requirements from other vendors. It is possible that these suppliers will not be able to obtain sufficient silicon or silicon wafers to satisfy their contractual obligations to us; and

•

our purchase of silicon-related materials is subject to the business risk of our suppliers, one or more of which may go out of business for any one of a number of reasons beyond our control in the current economic environment.

If we fail to obtain delivery of silicon-related materials in amounts and according to time schedules that we expect, we may be forced to reduce production, which will adversely affect our revenues. Our failure to obtain the required amounts of silicon-related materials on time and at commercially reasonable prices could substantially limit our ability to meet our contractual obligations to deliver PV products to our customers. Any failure by us to meet such obligations could have a material adverse effect on our reputation, retention of customers, market share, business and results of operations and may subject us to claims from our customers and other disputes.

We currently have a significant amount of debt outstanding. Our substantial indebtedness may limit our future financing capabilities and could adversely affect our business, financial condition and results of operations.

The principal amount of our total bank borrowings outstanding was RMB668.9 million (US$101.4 million) as of December 31, 2010 of which RMB318.9 million (US48.3 million) were short-term bank borrowings. In addition, we had US$172.5 million principal amount of convertible bonds, with fair value of RMB687.4 million (US$104.2 million), outstanding as of December 31, 2010. Our debt could have a significant impact on our future operations and cash flow, including:

•

making it more difficult for us to fulfill payment and other obligations under our outstanding debt, including repayment of our long- and short-term credit facilities should we be unable to obtain extensions for any such facilities before they mature, as well as our obligations under our convertible bonds;

•

triggering an event of default if we fail to comply with any of our payment or other obligations contained in our debt agreements, which could result in cross-defaults causing all or a substantial portion of our debt to become immediately due and payable;

•

reducing the availability of cash flow to fund working capital, capital expenditures, acquisitions and other general corporate purposes, and adversely affecting our ability to obtain additional financing for these purposes;

•

potentially increasing the cost of any additional financing; and

•

putting pressure on our ADS price due to concerns of our inability to repay our debt and making it more difficult for us to conduct equity financings in the capital markets.

Our ability to meet our payment and other obligations under our outstanding debt depends on our ability to generate cash flow in the future or to refinance such debt. We may not be able to generate sufficient cash flow from operations to enable us to meet our obligations under our outstanding debt and to fund other liquidity needs. If we are not able to generate sufficient cash flow to meet such obligations, we may need to refinance or restructure our debt, to sell our assets, to reduce or delay our capital investments, or to seek additional equity or debt financing. We cannot assure you that future financing will be available in amounts or on terms acceptable to us, if at all. In addition, the incurrence of additional indebtedness would result in increased interest rate risk and debt service obligations, and could result in operating and financing covenants that would further restrict our operations and limit our ability to obtain the financing required to fund future capital expenditures and working capital. As a result, our ability to plan for, or react effectively to, changing market conditions may be adversely and materially affected.

We require a significant amount of cash to fund our operations as well as meet future capital requirements. If we cannot obtain additional capital when we need it, our growth prospects and future profitability may be materially and adversely affected.

We typically require a significant amount of cash to fund our operations. We also require cash generally to meet future capital requirements, which are difficult to plan in the rapidly changing PV industry. The principal amount of our total bank borrowings outstanding was RMB668.9 million (US$101.4 million) as of December 31, 2010. We cannot assure you that future financing will be available on satisfactory terms, or at all. Our ability to obtain external financing in the future is subject to a variety of uncertainties, including:

•

our future financial condition, results of operations and cash flows;

•

general market conditions for financing activities by manufacturers of PV and related products; and

•

economic, political and other conditions in the PRC and elsewhere in the world.

If we are unable to obtain necessary financing in a timely manner or on commercially acceptable terms, or at all, our growth prospects and future profitability may decrease materially.

We face risks associated with the marketing, distribution and sale of our PV products internationally, and if we are unable to effectively manage these risks, our expansion may be materially and adversely affected.

A substantial majority of our revenue has been generated by sales to customers outside of China. The marketing, distribution and sale of our PV products overseas expose us to a number of risks, including:

•

fluctuations in currency exchange rates of the U.S. dollar, Euro and other foreign currencies against the Renminbi;

•

difficulty in engaging and retaining distributors and agents who are knowledgeable about, and can function effectively in, overseas markets;

•

increased costs associated with maintaining marketing and sales activities in various countries;

•

difficulty and costs relating to compliance with different commercial and legal requirements in the jurisdictions in which we offer our products;

•

inability to obtain, maintain or enforce intellectual property rights; and

•

trade barriers, such as export requirements, tariffs, taxes and other restrictions and expenses, which could increase the prices of our products and make us less competitive in some countries.

If we are unable to effectively manage these risks, our ability to conduct or expand our business abroad would be impaired, which may in turn have a material adverse effect on our business, financial condition, results of operations and prospects.

Changes in international trade policies and international barriers to trade may adversely affect our ability to export our products worldwide.

As our manufacturing facility and some of our customers are located in China, we and our customers may be affected by any claims of unfair trade practices that are brought against the PRC government through the imposition of tariffs, non-tariff barriers to trade or other trade remedies. On September 9, 2010, the United Steel Workers filed a petition with the United States Trade Representative, or USTR, alleging the PRC government has engaged in unfair trade policies and practices with respect to certain domestic industries, including the solar power industry. Subsequently, USTR initiated an investigation under Section 301 of the 1974 Trade Act, which is ongoing as of the date of this annual report. Although we believe we will not be directly affected by the results of this investigation, there can be no assurance that any government or international trade body will not institute adverse trade policies or remedies against exports from China in the future. Any significant changes in international trade policies, practices or trade remedies, especially those instituted in our target markets or markets where our major customers are located, could increase the price of our products compared to our competitors or decrease our customers’ demand for our products, which may adversely affect our business prospects and results of operations.

If we are unable to compete in the highly competitive PV market, our revenue and profits may decrease and we may lose market share.

The PV market is very competitive. We face competition from a number of PV manufacturers, including domestic, foreign and multinational corporations. We believe that the principal competitive factors in the markets for our products are:

•

manufacturing capacity;

•

power efficiency;

•

product offerings and quality of products;

•

price;

•

strength of supply chain and distribution network;

•

after-sales services; and

•

brand name recognition.

Many of our current and potential competitors have longer operating histories, access to larger customer bases and resources and significantly greater economies of scale than we do. In particular, many of our competitors are developing and manufacturing solar energy products based on new technologies that may ultimately have costs similar to, or lower than, our projected costs. In addition, our competitors may be able to respond more quickly to changing customer demands or devote more resources to the development, promotion and sales of their products than we can. Furthermore, competitors with more diversified product offerings may be better positioned to withstand a decline in the demand for PV products. Some of our competitors have also become vertically integrated, with businesses ranging from upstream silicon wafer manufacturing to solar power system integration. It is possible that new competitors or alliances among existing competitors could emerge and rapidly acquire significant market share, which would harm our business. For instance, several semiconductor manufacturers have already announced their intention to commence production of PV cells and PV modules. If we fail to compete successfully, our business would suffer and we may lose or be unable to gain market share and our financial condition and results of operations would be materially and adversely affected.

In addition, the PV market in general competes with other sources of renewable energy as well as conventional power generation. If prices for conventional and other renewable energy resources decline, or if these resources enjoy greater policy support than solar power, the PV market and our business and prospects could be materially and adversely affected.

Our profitability depends on our ability to respond to rapid market changes in the PV industry, including by developing new technologies and offering additional products and services.

The PV industry is characterized by rapid changes in the diversity and complexity of technologies, products and services. In particular, the ongoing evolution of technological standards requires products with improved features, such as more efficient and higher power output and improved aesthetics. As a result, we expect that we will need to develop, or obtain access to, advances in technologies on a continuous basis in order for us to respond to competitive market conditions and customer demands. In addition, advances in technologies typically lead to declining average selling prices for products using older technologies or make our current products less competitive or obsolete. As a result, the profitability of any given product, and our overall profitability, may decrease over time.

In addition, we will need to invest significant financial resources in research and development to maintain our competitiveness and keep pace with technological advances in the PV industry. However, commercial acceptance by customers of new products we offer may not occur at the rate or level expected, and we may not be able to successfully adapt existing products to effectively and economically meet customer demands, thus impairing the return from our investments. We may also be required under the applicable accounting standards to recognize a charge for the impairment of assets to the extent our existing products become uncompetitive or obsolete, or if any new products fail to achieve commercial acceptance. Any such charge may have a material adverse effect on our financial condition and results of operations.

Moreover, in response to the rapidly evolving conditions in the PV industry, we started to expand our business downstream to provide system integration products and services in 2010. This expansion requires significant investment and management attention from us, and we are likely to face intense competition from companies that have extensive experience and well-established businesses and customer bases in the system integration sector. We cannot assure you that we will succeed in expanding our business downstream. If we are not able to bring quality products and services to market in a timely and cost-effective manner and successfully market and sell these products and services, our ability to continue penetrating the PV market, as well as our results of operations and profitability, will be materially and adversely affected.

Our future success also depends on our ability to make strategic acquisitions and investments and to establish and maintain strategic alliances, and failure to do so could have a material adverse effect on our market penetration, revenue growth and profitability. In addition, such strategic acquisitions, alliances and investments themselves entail significant risks that could materially and adversely affect our business.

We are pursuing expansion into PV system integration services through our subsidiary, Shanghai Linyang Solar Technology Co., Ltd., or Solar Shanghai, and we may pursue upstream silicon feedstock sourcing through strategic partnerships and investments in the future. We may also establish strategic alliances with third parties in the PV industry to develop new technologies and to expand our marketing channels. These types of transactions could require that our management develop expertise in new areas, make significant investments in research and development, manage new business relationships and attract new types of customers. They may also require significant attention from our management, which could have a material adverse effect on our ability to manage our business. We may also experience difficulties integrating acquisitions and investments into our existing business and operations and retaining key technical and managerial personnel of acquired companies.

Strategic acquisitions, investments and alliances with third parties may be expensive to implement and could subject us to a number of risks, including risks associated with sharing proprietary information and loss of control of operations that are material to our business. We may assume unknown liabilities or other unanticipated events or circumstances through acquisitions and investments. Moreover, strategic acquisitions, investments and alliances subject us to the risk of non-performance by a counterparty, which may in turn lead to monetary losses that materially and adversely affect our business. As a result, we may not be able to successfully make such strategic acquisitions and investments or to establish strategic alliances with third parties that will prove to be effective or beneficial for our business. Any difficulty we face in this regard could have a material adverse effect on our market penetration, results of operations and profitability.

Problems with product quality or product performance could result in a decrease in customers and revenue, unexpected expenses and loss of market share. In addition, product liability or warranty claims against us could result in adverse publicity and potentially significant monetary damages.

Our PV products are typically sold with a two to five-year unlimited warranty for technical defects, a 10-year limited warranty against declines of greater than 10%, and a 20 to 25-year limited warranty against declines of greater than 20%, in their initial power generation capacity. Since our products have been in use for only a relatively short period, our assumptions regarding the durability and reliability of our products may not be accurate. We consider various factors when determining the likelihood of product defects, including an evaluation of our quality controls, technical analysis, industry information on comparable companies and our own experience. As of December 31, 2008, 2009 and 2010, our accrued warranty costs for the two to five years warranty against technical defects totaled RMB48.6 million, RMB73.5 million and RMB131.7 million (US$20.0 million), respectively. If our PV modules fail to perform to the standards of the performance guarantee, we could incur substantial expenses and substantial cash outlays to repair, replace or provide refunds for the under-performing products, which could negatively impact our overall cash position. Any increase in the defect rate of our products would increase the amount of our warranty costs and we may not have adequate warranty provision to cover such warranty costs, which would have a negative impact on our results of operations.

In addition, we purchase silicon-related materials and other components that we use in our products from third parties. Unlike PV modules, which are subject to certain uniform international standards, silicon-related materials generally do not have uniform international standards, and it is often difficult to determine whether product defects are caused by defects in silicon, silicon wafers or other components of our products or caused by other reasons. Even assuming that our product defects are caused by defects in raw materials, we may not be able to recover our warranty costs from our suppliers because the agreements we entered into with our suppliers typically contain no or only limited warranties. The possibility of future product failures could cause us to incur substantial expense to provide refunds or resolve disputes with regard to warranty claims through litigation, arbitration or other means, or damage our market reputation and cause our sales to decline.

As with other PV product manufacturers, we are exposed to risks associated with product liability claims if the use of the PV products we sell results in injury, death or damage to property. We cannot predict whether product liability claims will be brought against us in the future or the effect of any resulting negative publicity on our business. See “— We have limited insurance coverage and may incur losses resulting from product liability claims or business interruptions.”

If PV technology is not suitable for widespread adoption, or sufficient demand for PV products does not develop or takes longer to develop than we anticipated, our sales may not continue to increase or may even decline, and our revenue and profitability would be reduced.

The PV market is at a relatively early stage of development and the extent to which PV products will be widely adopted is uncertain. Furthermore, market data in the PV industry are not as readily available as those in other more established industries, where trends can be assessed more reliably from data gathered over a longer period of time. If PV technology, in particular the type of PV technology that we have adopted, proves unsuitable for widespread adoption or if demand for PV products fails to develop sufficiently, we may not be able to grow our business or generate sufficient revenue to sustain our profitability. In addition, demand for PV products in our targeted markets, including China, may not develop or may develop to a lesser extent than we anticipated. Many factors may affect the viability of widespread adoption of PV technology and demand for PV products, including:

•

cost-effectiveness of PV products compared to conventional and other non-solar energy sources and products;

•

performance and reliability of PV products compared to conventional and other non-solar energy sources and products;

•

availability of government subsidies and incentives to support the development of the PV industry or other energy resource industries;

•

success of other alternative energy generation technologies, such as fuel cells, wind power and biomass;

•

fluctuations in economic and market conditions that affect the viability of conventional and non-solar alternative energy sources, such as increases or decreases in the prices of oil and other fossil fuels;

•

capital expenditures by end users of PV products, which tend to decrease when the overall economy slows down; and

•

deregulation of the electric power industry and the broader energy industry.

One of our existing shareholders has substantial influence over our company and its interests may not be aligned with the interests of our other shareholders.

Hanwha Solar owns approximately 49.8% of our outstanding share capital as of April 22, 2011. Pursuant to a shareholder agreement between Hanwha Solar and our company dated September 16, 2010, Hanwha Solar has the right to designate three directors to our board and veto major corporate actions. Hanwha Solar has substantial influence over our business, including decisions regarding mergers, consolidations and the sale of all or substantially all of our assets, election of directors and other significant corporate actions. This concentration of ownership may discourage, delay or prevent a change in control of our company, which could deprive our shareholders of an opportunity to receive a premium for its shares as part of a sale of our company and might reduce the price of our ADSs. In addition, without the consent of Hanwha Solar, we could be prevented from entering into transactions that could be beneficial to us. Hanwha Solar may cause us to take actions that are opposed by other shareholders as its interests may differ from those of other shareholders.

Existing regulations and policies governing the electricity utility industry, as well as changes to regulations and policies affecting PV products, may adversely affect demand for our products and materially reduce our revenue and profits.

The electric utility industry is subject to extensive regulation, and the market for PV products is heavily influenced by these regulations as well as the policies promulgated by electric utilities. These regulations and policies often affect electricity pricing and technical interconnection of end-user power generation. As the market for solar and other alternative energy sources continue to evolve, these regulations and policies are being modified and may continue to be modified. Customer purchases of, or further investment in research and development of, solar and other alternative energy sources may be significantly affected by these regulations and policies, which could significantly reduce demand for our products and materially reduce our revenue and profits.

Moreover, we expect that our PV products and their installation will be subject to oversight and regulation in accordance with national and local ordinances relating to building codes, safety, environmental protection, utility interconnection and metering and related matters in various countries. We also have to comply with the requirements of individual localities and design equipment to comply with varying standards applicable in the jurisdictions where we conduct business. Any new government regulations or utility policies pertaining to our PV products may result in significant additional expenses to us, our distributors and end users and, as a result, could cause a significant reduction in demand for our PV products, as well as materially and adversely affect our financial condition and results of operations.

The lack or inaccessibility of subsidies or financing for off-grid solar energy applications could cause our sales to decline.

Some of our products are used for “off-grid” solar energy applications in developed and developing countries, where solar energy is provided to end users independent of an electricity transmission grid. In some countries, government agencies and the private sector have, from time to time, provided subsidies or financing on preferred terms for rural electrification programs. We believe that the availability of financing could have a significant effect on the level of sales of off-grid solar energy applications, particularly in developing countries where users may not have sufficient resources or credit to otherwise acquire PV systems. If existing subsidies or financing programs for off-grid solar energy applications are eliminated or if financing becomes inaccessible, the growth of the market for off-grid solar energy applications may be materially and adversely affected, which may cause our sales to decline.

Our failure to protect our intellectual property rights may undermine our competitive position, and litigation to protect our intellectual property rights may be costly.

We rely primarily on patents, trademarks, trade secrets, copyrights and other contractual restrictions to protect our intellectual property. Nevertheless, these afford only limited protection and the actions we take to protect our intellectual property rights may not be adequate. In particular, implementation of PRC intellectual property-related laws has historically been lacking, primarily because of ambiguities in the PRC laws and difficulties in enforcement. Accordingly, intellectual property rights and confidentiality protections in China may not be as effective as in the United States or other countries. Policing unauthorized use of our proprietary technologies can be difficult and expensive. In addition, litigation may be necessary to enforce our intellectual property rights, protect our trade secrets or determine the validity and scope of the proprietary rights of others. We also cannot assure you that the outcome of any such litigation would be in our favor. An adverse determination in any such litigation will impair our intellectual property rights and may harm our business, prospects and reputation. Furthermore, any such litigation may be costly and may divert management attention away from our business as well as require us to expend other resources. We have no insurance coverage against litigation costs and would have to bear all costs arising from such litigation to the extent we are unable to recover them from other parties. The occurrence of any of the foregoing could have a material adverse effect on our business, financial condition and results of operations.

We may be exposed to infringement or misappropriation claims by third parties, particularly in jurisdictions outside China which, if determined adversely against us, could disrupt our business and subject us to significant liability to third parties, as well as have a material adverse effect on our financial condition and results of operations.

Our success depends, in large part, on our ability to use and develop our technologies and know-how without infringing the intellectual property rights of third parties. As we continue to market and sell our products internationally, and as litigation becomes more common in the PRC, we face a higher risk of being the subject of claims for intellectual property infringement, as well as having indemnification relating to other parties’ proprietary rights held to be invalid. Our current or potential competitors, many of which have substantial resources and have made substantial investments in competing technologies, may have or may obtain patents that will prevent, limit or interfere with our ability to make, use or sell our products in the European Union, the PRC or other countries. The validity and scope of claims relating to PV technology patents involve complex, scientific, legal and factual questions and analysis and, therefore, may be highly uncertain. In addition, the defense of intellectual property claims, including patent infringement suits, and related legal and administrative proceedings can be both costly and time consuming, and may significantly divert the efforts and resources of our technical and management personnel. Furthermore, an adverse determination in any such litigation or proceeding to which we may become a party could cause us to:

•

pay damage awards;

•

seek licenses from third parties;

•

pay ongoing royalties;

•

redesign our products; or

•

be restricted by injunctions,

each of which could effectively prevent us from pursuing some or all of our business and result in our customers or potential customers deferring or limiting their purchase or use of our products, which could have a material adverse effect on our financial condition and results of operations.

We may not be able to obtain sufficient patent protection on the technologies embodied in the PV products we currently manufacture and sell, which could reduce our competitiveness and increase our expenses.

Although we rely primarily on trade secret laws and contractual restrictions to protect the technologies in the PV cells and PV modules we currently manufacture and sell, our success and ability to compete in the future may also depend to a significant degree on obtaining patent protection for our proprietary technologies. As of April 30, 2011, we had 20 issued patents and 14 pending patent applications in the PRC. We do not have, and have not applied for, any patents for our proprietary technologies outside the PRC. As the protections afforded by our patents are effective only in the PRC, our competitors and other companies may independently develop substantially equivalent technologies or otherwise gain access to our proprietary technologies, and obtain patents for such technologies in other jurisdictions, including the countries in which we sell our products. Moreover, our patent applications in the PRC may not result in issued patents, and even if they do result in issued patents, the patents may not have claims of the scope we seek. In addition, any issued patents may be challenged, invalidated or declared unenforceable. As a result, our present and future patents may provide only limited protection for our technologies, and may not be sufficient to provide competitive advantages to us.

We depend on our key personnel, and our business and growth may be severely disrupted if we lose their services or fail to recruit new qualified personnel.

Our future success depends substantially on the continued services of some of our directors and key executives. If we lose the services of one or more of our current directors and executive officers, we may not be able to replace them readily, if at all, with suitable or qualified candidates, and may incur additional expenses to recruit and retain new directors and officers, particularly those with a significant mix of both international and China-based PV industry experience similar to our current directors and officers, which could severely disrupt our business and growth. In addition, if any of our directors or executives joins a competitor or forms a competing company, we may lose some of our customers. Each of these directors and executive officers has entered into an employment agreement with us, which contains confidentiality and non-competition provisions. However, if any disputes arise between these directors or executive officers and us, it is not clear the extent to which any of these agreements could be enforced outside of the United States, where most of these directors and executive officers reside and hold some of their assets, particularly in light of uncertainties associated with the PRC legal system. See “— Risks Related to Doing Business in China — Uncertainties with respect to the PRC legal system could have a material adverse effect on us.” Furthermore, as we expect to continue to expand our operations and develop new products, we will need to continue attracting and retaining experienced management and key research and development personnel.

Competition for personnel in the PV industry in China is intense, and the availability of suitable and qualified candidates is limited. In particular, we compete to attract and retain qualified research and development personnel with other PV technology companies, universities and research institutions. Competition for these individuals could cause us to offer higher compensation and other benefits in order to attract and retain them, which could have a material adverse effect on our financial condition and results of operations. We may also be unable to attract or retain the personnel necessary to achieve our business objectives, and any failure in this regard could severely disrupt our business and growth.

Any failure to achieve and maintain effective internal control could have a material adverse effect on our business, results of operations and the market price of our ADSs.

The SEC, as required by Section 404 of the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, adopted rules requiring most public companies to include a management report on such company’s internal control over financial reporting in its annual report, which contains management’s assessment of the effectiveness of the company’s internal control over financial reporting. In addition, when a company meets the SEC’s criteria, an independent registered public accounting firm must report on the effectiveness of the company’s internal control over financial reporting.

Our management and independent registered public accounting firm have concluded that our internal control over financial reporting as of December 31, 2010 was effective. However, we cannot assure you that in the future our management or our independent registered public accounting firm will not identify material weaknesses during the Section 404 of the Sarbanes-Oxley Act audit process or for other reasons. In addition, because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. As a result, if we fail to maintain effective internal control over financial reporting or should we be unable to prevent or detect material misstatements due to error or fraud on a timely basis, investors could lose confidence in the reliability of our financial statements, which in turn could harm our business, results of operations and negatively impact the market price of our ADSs, and harm our reputation. Furthermore, we have incurred and expected to continue to incur considerable costs and to use significant management time and other resources in an effort to comply with Section 404 and other requirements of the Sarbanes-Oxley Act.

We have limited insurance coverage and may incur losses resulting from business interruptions or product liability claims.

We are subject to risk of explosion and fires, as highly flammable gases, such as silane and nitrogen gas, are generated in our manufacturing processes. While we have not experienced to date any major explosion or fire, the risks associated with these gases cannot be completely eliminated. In addition, a natural disaster such as floods or earthquakes, or other unanticipated catastrophic events, including power interruption, telecommunications failures, equipment failures, explosions, fires, break-ins, terrorist attacks or acts or wars, could significantly disrupt our ability to manufacture our products and to operate our business. If any of our production facilities or material equipment were to experience any significant damage or downtime, we might be unable to meet our production targets and our business could suffer. Although we have obtained business interruption insurance, it may not be able to fully cover losses caused by the business interruption because business interruption insurance available in China offers limited coverage compared to that offered in many other countries.

We are also exposed to risks associated with product liability claims in the event that the use of the PV products we sell results in injury, death or damage to property. Due to limited historical experience, we are unable to predict whether product liability claims will be brought against us in the future or the effect of any resulting adverse publicity on our business. Moreover, we only have limited product liability insurance and may not have adequate resources to satisfy a judgment in the event of a successful claim against us. The successful assertion of product liability claims against us could result in potentially significant monetary damages and require us to make significant payments, which could materially and adversely affect our business, financial condition and results of operations.

Any environmental claims or failure to comply with any present or future environmental regulations may require us to spend additional funds and may materially and adversely affect our financial condition and results of operations.

We are subject to a variety of laws and regulations relating to the use, storage, discharge and disposal of chemical by products of, and water used in, our manufacturing operations and research and development activities, including toxic, volatile and otherwise hazardous chemicals and wastes. We are in all material respects in compliance with current PRC environmental regulations to conduct our business as it is presently conducted. Although we have not suffered material environmental claims in the past, failure to comply with any present or future regulations could result in the assessment of damages or imposition of fines against us, suspension of production or a cessation of our operations. New regulations could also require us to acquire costly equipment or to incur other significant expenses. Any failure by us to control the use of, or to adequately restrict the discharge of, hazardous substances could subject us to potentially significant monetary damages and fines or suspension of our business, as well as our financial condition and results of operations.

The use of certain hazardous substances, such as lead, in various products is also coming under increasingly stringent governmental regulation. Increased environmental regulation in this area could adversely impact the manufacture and sale of solar modules that contain lead and could require us to make unanticipated environmental expenditures. For example, the European Union Directive 2002/96/EC on Waste Electrical and Electronic Equipment, or the WEEE Directive, requires manufacturers of certain electrical and electronic equipment to be financially responsible for the collection, recycling, treatment and disposal of specified products placed on the market in the European Union. In addition, European Union Directive 2002/95/EC on the Restriction of the use of Hazardous Substances in electrical and electronic equipment, or the RoHS Directive, restricts the use of certain hazardous substances, including lead, in specified products. Other jurisdictions are considering adopting similar legislation. Currently, we are not required under the WEEE or RoHS Directives to collect, recycle or dispose any of our products. However, the Directives allow for future amendments subjecting additional products to the Directives’ requirements. If, in the future, our PV products become subject to such requirements, we may be required to apply for an exemption. If we were unable to obtain an exemption, we would be required to redesign our PV products in order to continue to offer them for sale within the European Union, which would be impractical. Failure to comply with the Directives could result in fines and penalties, inability to sell our PV products in the European Union, competitive disadvantages and loss of net sales, all of which could have a material adverse effect on our business, financial condition and results of operations.

Our business benefits from certain PRC government incentives. Expiration of, or changes to, these incentives could have a material adverse effect on our results of operations.

On March 16, 2007, the PRC government promulgated the Law of the People’s Republic of China on the Enterprise Income Tax, or the EIT, which took effect on January 1, 2008. Under the EIT, domestically owned enterprises and foreign invested enterprises, or FIEs, are subject to a uniform tax rate of 25%. While the EIT equalizes the tax rates for FIEs and domestically owned enterprises, preferential tax treatment continues to be granted to companies in certain encouraged sectors, and entities classified as “high and new technology enterprises” are entitled to a 15% EIT rate, whether domestically owned enterprises or FIEs. The EIT also provides a five-year transition period starting from its effective date for those enterprises which were established before the promulgation date of the EIT and which were entitled to a preferential lower tax rate or tax holiday under the then effective tax laws or regulations. The tax rate of such enterprises is transitioning to the uniform tax rate within a five-year transition period and the tax holiday, which was enjoyed by such enterprises before the effective date of the EIT, may continue to be enjoyed until the end of the holiday. Hanwha SolarOne (Qidong) Co., Ltd. or SolarOne Qidong, our wholly owned operating subsidiary in China, was approved to be qualified as a “high and new technology enterprise” on October 21, 2008. The “high and new technology enterprise” status is valid for a period of three years from the date of issuance of the certificate and is subject to an annual self-review process whereby a form is submitted to relevant tax authority for approval to use a beneficial income tax rate. If there are significant changes in the business operations, manufacturing technologies or other criteria that cause the enterprise to no longer meet the criteria as a “high and new technology enterprise,” such status will be terminated from the year of such change. If SolarOne Qidong fails to qualify as a “high and new technology enterprise” in future periods, our income tax expenses would increase, which could have a material and adverse effect on our net income and results of operations.

In accordance with the former PRC Income Tax Law for Enterprises with Foreign Investment and Foreign Enterprises, or the FIE Tax Law, the EIT and the related implementing rules, SolarOne Qidong was exempted from enterprise income tax in 2005 and 2006, and was taxed at a reduced rate of 12% in 2007, 12.5% in 2008, 12.5% in 2009 and 15% in 2010. The “high and new technology enterprise” status of SolarOne Qidong will expire in October 2011. SolarOne Qidong has re-applied for the “high and new technology enterprise” qualification and expects to receive a response from the government regarding the application by August 2011. If SolarOne Qidong’s application is approved, SolarOne Qidong will continue to enjoy a preferential income tax rate of 15% in 2011, 2012 and 2013, and otherwise SolarOne Qidong will be subject to an income tax rate of 25% from 2011. In 2010, we recorded a provision of RMB116.1 million (US$17.6 million) for unrecognized tax benefits related to SolarOne Qidong due to the uncertainty as to whether it would meet certain requirements of “high and new technology enterprise” status during its annual self-assessment in order to be eligible for the reduced EIT rate of 15%. From 2005 until the end of 2009, SolarOne Qidong was also exempted from the 3% local income tax.

Any reduction or elimination of the preferential tax treatments currently enjoyed by us may significantly increase our income tax expenses and materially reduce our net income, which could have a material adverse effect on our financial condition and results of operations.

Under the EIT, we may be classified as a “Resident Enterprise” of the PRC. Such classification would likely result in negative tax consequences to us and could result in negative tax consequences to our non-PRC shareholders and ADS holders.

Under the EIT, enterprises established under the laws of non-PRC jurisdictions but whose “de facto management body” is located in the PRC are considered “resident enterprises” for PRC tax purposes and are subject to the EIT. According to the Implementation Regulations for the EIT of the PRC issued by the State Council on December 6, 2007, a de facto management body is defined as an establishment that exerts substantial and comprehensive management and control over the business operations, staff, accounting, assets and other aspects of the enterprise. Since substantially all of our management is currently based in the PRC, and may remain in the PRC in the foreseeable future, it is likely that we will be regarded as a “resident enterprise” on a strict application of the EIT and its Implementation Regulations. As of December 31, 2010, we recorded unrecognized tax benefits of RMB143.5 million (US$21.7 million), RMB27.4 million (US$4.1 million) of which was recorded because based on our judgment, we may be deemed as a PRC tax resident pursuant to the EIT. If Hanwha SolarOne Co., Ltd., our holding company, or any of its non-PRC subsidiaries is treated as a “resident enterprise” for PRC tax purposes, Hanwha SolarOne or such subsidiary will be subject to PRC income tax on worldwide income at a uniform tax rate of 25%, which would have a material adverse effect on our financial condition and results of operations.

In addition, although the EIT provides that dividend income payments between qualified “resident enterprises” are exempted from the 10% withholding tax, it is still not free of doubt whether we will be considered to be a qualified “resident enterprise” under the EIT. If we are considered a “non-resident enterprise,” dividends paid to us by our subsidiaries in the PRC (through our holding company structure), if any, may be subject to the 10% withholding tax. If we are deemed by the PRC tax authorities to be a “resident enterprise” and declare dividends, under the existing Implementation Regulations of the EIT, dividends paid by us to our shareholders and ADS holders, which are “non-resident enterprises” and do not have an establishment or place of business in the PRC, or which have such an establishment or place of business but the relevant income is not effectively connected with the establishment or place of business, might be subject to PRC withholding tax at 10% or a lower treaty rate.

Similarly, any gain realized on the transfer of ADSs or shares by non-PRC investors, which are “non-resident enterprises,” is also subject to PRC withholding income tax at 10% or a lower treaty rate if such gain is regarded as income derived from sources within the PRC.

According to the Law of the People’s Republic of China on the Individual Income Tax, or the IIT, as amended, PRC income tax at the rate of 20% is applicable to dividends payable to individual investors if such dividends are regarded as income derived from sources within the PRC. Similarly, any gain realized on the transfer of ADSs or ordinary shares by individual investors is also subject to PRC tax at 20% if such gain is regarded as income derived from sources within the PRC. If we are deemed by the PRC tax authorities as a “resident enterprise,” the dividends we pay to our individual investors with respect to our ordinary shares or ADSs, or the gain the individual investors may realize from the transfer of our ordinary shares or ADSs, might be treated as income derived from sources within the PRC and be subject to PRC tax at 20% or a lower treaty rate.

Fluctuations in exchange rates could adversely affect our business as well as result in foreign currency exchange losses.

Our financial statements are expressed in, and our functional currency is Renminbi. The change in value of the Renminbi against the U.S. dollar, Euro and other currencies is affected by, among other things, changes in China’s political and economic conditions. On July 21, 2005, the PRC government changed its decade-old policy of pegging the value of the Renminbi to the U.S. dollar. Under the new policy, the Renminbi is permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. This change in policy has resulted in appreciation of the Renminbi against the U.S. dollar. The PRC government may decide to adopt an even more flexible currency policy in the future, which could result in a further and more significant appreciation of the Renminbi against the U.S. dollar. An appreciation of the Renminbi relative to other foreign currencies could decrease the per unit revenue generated from our international sales. If we increased our pricing to compensate for the reduced purchasing power of foreign currencies, we may decrease the market competitiveness, on a price basis, of our products. This could result in a decrease in our international sales and materially and adversely affect our business.

A substantial portion of our sales is denominated in U.S. dollars and Euros, while a substantial portion of our costs and expenses is denominated in Renminbi. As a result, the revaluation of the Renminbi starting in July 2005 has increased, and further revaluations could further increase, our costs. The value of, and any dividends payable on, our ADSs in foreign currency terms will also be affected. Conversely, if we decide to convert our Renminbi into U.S. dollars for the purpose of making payments for dividends on our ordinary shares or ADSs or for other business purposes, an appreciation of the U.S. dollar against the Renminbi would have a negative effect on the U.S. dollar amount available to us.

Fluctuations in exchange rates, particularly among the U.S. dollar, Renminbi and Euro, also affect our gross and net profit margins and could result in fluctuations in foreign exchange and operating gains and losses. We incurred net foreign currency losses of RMB35.2 million, RMB23.8 million and RMB89.3 million (US$13.5 million) in 2008, 2009 and 2010, respectively. In particular, a substantial portion of our net revenues is currently denominated in Euros. Since December 2009, the Euro has fluctuated significantly. A depreciation of the Euro may also have a negative impact on the selling prices of our products in Renminbi terms. We cannot predict the impact of future exchange rate fluctuations on our financial condition and results of operations, and we may incur net foreign currency losses in the future.

While we started to enter into economic hedging transactions in 2008 to minimize the impact of short-term foreign currency fluctuations on our revenues that are denominated in a currency other than Renminbi, the effectiveness of these transactions may be limited and we may not be able to successfully hedge all of our exposure.

Our estimates of future revenues that are denominated in foreign currencies may not be accurate, which could result in foreign exchange losses. Any default by the counterparties to these transactions could also adversely affect our financial condition and results of operations. In addition, our foreign currency exchange losses may be magnified by PRC exchange control regulations that restrict our ability to convert Renminbi into foreign currencies.

Risks Related to Doing Business in China

Adverse changes in political and economic policies of the PRC government could have a material adverse effect on the overall economic growth of China, which could reduce the demand for our products and materially and adversely affect our competitive position.

Substantially all of our operations are conducted in China and some of our sales are made in China. Accordingly, our business, financial condition, results of operations and prospects are affected significantly by economic, political and legal developments in China. The PRC economy differs from the economies of most developed countries in many respects, including:

•

the amount of government involvement;

•

the level of development;

•

the growth rate;

•

the control of foreign exchange; and

•

the allocation of resources.

While the PRC economy has grown significantly since the late 1970s, the growth has been uneven, both geographically and among various sectors of the economy. The PRC government has implemented various measures to encourage economic growth and guide the allocation of resources. Some of these measures benefit the overall PRC economy, but may also have a negative effect on us. For example, our financial condition and results of operations may be adversely affected by government control over capital investments or changes in tax regulations that are applicable to us.

The PRC economy has been transitioning from a planned economy to a more market-oriented economy. Although the PRC government has in recent years implemented measures emphasizing the utilization of market forces for economic reform, the reduction of state ownership of productive assets and the establishment of sound corporate governance in business enterprises, a substantial portion of the productive assets in China is still owned by the PRC government. The continued control of these assets and other aspects of the national economy by the PRC government could materially and adversely affect our business. The PRC government also exercises significant control over economic growth in China through the allocation of resources, controlling payment of foreign currency-denominated obligations, setting monetary policy and providing preferential treatment to particular industries or companies. Efforts by the PRC government to slow the pace of growth of the PRC economy could result in decreased capital expenditure by solar energy users, which in turn could reduce demand for our products.

Any adverse change in the economic conditions or government policies in China could have a material adverse effect on the overall economic growth and the level of renewable energy investments and expenditures in China, which in turn could lead to a reduction in demand for our products and consequently have a material adverse effect on our business and prospects. In particular, the PRC government has, in recent years, promulgated certain laws and regulations and initiated certain government-sponsored programs to encourage the utilization of new forms of energy, including solar energy. We cannot assure you that the implementation of these laws, regulations and government programs will be beneficial to us. In particular, any adverse change in the PRC government’s policies towards the PV industry may have a material adverse effect on our operations as well as on our plans to expand our business into downstream system integration services.

Uncertainties with respect to the PRC legal system could have a material adverse effect on us.

We conduct substantially all of our business through our operating subsidiary in the PRC, SolarOne Qidong, a Chinese wholly foreign-owned enterprise. SolarOne Qidong is generally subject to laws and regulations applicable to foreign investment in China and, in particular, laws applicable to wholly foreign-owned enterprises. The PRC legal system is based on written statutes, and prior court decisions may be cited for reference but have limited precedential value. Since 1979, PRC legislation and regulations have significantly enhanced the protections afforded to various forms of foreign investments in China. However, since these laws and regulations are relatively new and the PRC legal system continues to rapidly evolve, the interpretations of many laws, regulations and rules are not always uniform and enforcement of these laws, regulations and rules involve uncertainties, which may limit legal protections available to us. In addition, any litigation in China may be protracted and result in substantial costs and diversion of resources and management attention.

Limitations on the ability of our operating subsidiary to pay dividends or other distributions to us could have a material adverse effect on our ability to conduct our business.

We are a holding company and conduct substantially all of our business through our operating subsidiary, SolarOne Qidong, which is a limited liability company established in China. The payment of dividends by entities organized in, if any, China is subject to limitations. In particular, regulations in the PRC currently permit payment of dividends only out of accumulated profits as determined in accordance with PRC accounting standards and regulations. SolarOne Qidong is also required to set aside at least 10% of its annual after-tax profit based on PRC accounting standards each year to its general reserves until the accumulative amount of such reserves reaches 50% of its registered capital. These reserves are not distributable as cash dividends. In addition, SolarOne Qidong is required to allocate a portion of its after-tax profit to its staff welfare and bonus fund at the discretion of its board of directors. Moreover, if SolarOne Qidong incurs debt on its own behalf in the future, the instruments governing the debt may restrict its ability to pay dividends or make other distributions to us.

Restrictions on currency exchange may limit our ability to receive and use our revenue effectively.

A portion of our revenue and a substantial portion of our expenses are denominated in Renminbi. The Renminbi is currently convertible under the “current account,” which includes dividends, trade and service-related foreign exchange transactions, but not under the “capital account,” which includes foreign direct investment and loans. Currently, SolarOne Qidong may purchase foreign currencies for settlement of current account transactions, including payments of dividends to us, without the approval of the State Administration of Foreign Exchange, or SAFE. However, the relevant PRC government authorities may limit or eliminate our ability to purchase foreign currencies in the future. Since a significant amount of our future revenue will be denominated in Renminbi, any existing and future restrictions on currency exchange may limit our ability to utilize revenue generated in Renminbi to fund our business activities outside China that are denominated in foreign currencies.

Foreign exchange transactions by SolarOne Qidong under the capital account continue to be subject to significant foreign exchange controls and require the approval of or need to register with PRC governmental authorities, including SAFE. In particular, if SolarOne Qidong borrows foreign currency loans from us or other foreign lenders, these loans must be registered with SAFE, and if we finance SolarOne Qidong by means of additional capital contributions, these capital contributions must be approved by certain government authorities, including the National Development and Reform Commission, or the NDRC, the Ministry of Commerce or their respective local counterparts. These limitations could affect the ability of SolarOne Qidong to obtain foreign exchange through debt or equity financing.

PRC regulations relating to the establishment of offshore special purpose companies by PRC residents may subject our PRC resident shareholders to personal liability and limit our ability to acquire PRC companies or to inject capital into our PRC subsidiary, limit our PRC subsidiary’s ability to distribute profits to us, or otherwise materially and adversely affect us.

SAFE issued a public notice in October 2005, or the SAFE notice, requiring PRC residents, including both legal persons and natural persons, to register with the competent local SAFE branch before establishing or controlling any company outside of China, referred to as an “offshore special purpose company,” for the purpose of acquiring any assets of or equity interest in PRC companies and raising fund from overseas. In addition, any PRC resident that is the shareholder of an offshore special purpose company is required to amend its SAFE registration with the local SAFE branch, with respect to that offshore special purpose company in connection with any increase or decrease of capital, transfer of shares, merger, division, equity investment or creation of any security interest over any assets located in China. If any PRC shareholder of any offshore special purpose company fails to make the required SAFE registration and amendment, the PRC subsidiaries of that offshore special purpose company may be prohibited from distributing their profits and proceeds from any reduction in capital, share transfer or liquidation to the offshore special purpose company. Moreover, failure to comply with the SAFE registration and amendment requirements described above could result in liability under PRC laws for evasion of applicable foreign exchange restrictions. Our current beneficial owners who are PRC residents have registered with the local SAFE branch as required under the SAFE notice. The failure of these beneficial owners to amend their SAFE registrations in a timely manner pursuant to the SAFE notice or the failure of future beneficial owners of our company who are PRC residents to comply with the registration procedures set forth in the SAFE notice may subject such beneficial owners to fines and legal sanctions and may also result in a restriction on our PRC subsidiary’s ability to distribute profits to us or otherwise materially and adversely affect our business. In addition, the NDRC promulgated a rule in October 2004, or the NDRC Rule, which requires NDRC approvals for overseas investment projects made by PRC entities. The NDRC Rule also provides that approval procedures for overseas investment projects of PRC individuals shall be implemented with reference to this rule. However, there exist extensive uncertainties in terms of interpretation of the NDRC Rule with respect to its application to a PRC individual’s overseas investment, and in practice, we are not aware of any precedents that a PRC individual’s overseas investment has been approved by the NDRC or challenged by the NDRC based on the absence of NDRC approval. Our current beneficial owners who are PRC individuals did not apply for NDRC approval for investment in us. We cannot predict how and to what extent this will affect our business operations or future strategy. For example, the failure of our shareholders who are PRC individuals to comply with the NDRC Rule may subject these persons or our PRC subsidiary to certain liabilities under PRC laws, which could adversely affect our business.

We face uncertainties with respect to application of the Circular on Strengthening the Administration of Enterprise Income Tax for Share Transfer of Non-PRC Resident Enterprises.

Pursuant to the Notice on Strengthening Administration of Enterprise Income Tax for Share Transfers by Non-PRC Resident Enterprises, or SAT Circular 698, issued by the State Administration of Taxation on December 10, 2009 with retroactive effect from January 1, 2008, where a non-resident enterprise transfers its equity interests in a PRC resident enterprise indirectly via disposing of the equity interests of an overseas holding company, or an Indirect Transfer, and such overseas holding company is located in a tax jurisdiction that (i) has an effective tax rate less than 12.5% or (ii) does not tax foreign income of its residents, the foreign investor shall report such Indirect Transfer to the competent tax authority of the PRC resident enterprise. The PRC tax authority will examine the true nature of the Indirect Transfer, and if the tax authority considers that the foreign investor has adopted an abusive arrangement in order to avoid PRC tax, it will disregard the existence of the overseas holding company and re-characterize the Indirect Transfer and, as a result, gains derived from such Indirect Transfer may be subject to PRC withholding tax at the rate of up to 10%. SAT Circular 698 also provides that, where a non-PRC resident enterprise transfers its equity interests in a PRC resident enterprise to its related parties at a price lower than the fair market value, the relevant tax authority has the power to make a reasonable adjustment to the taxable gain of the transaction.

There is uncertainty as to the application of SAT Circular 698. The relevant PRC authority has not yet promulgated any formal provisions or formally declared or stated how to calculate the effective tax in a foreign jurisdiction and how a foreign investor shall report to the competent tax authority an Indirect Transfer. SAT Circular 698 states that it does not apply to purchases or sales of stock on a stock exchange. If we transfer our equity interest in our PRC subsidiaries or when our non-resident investors transfer their shares, we or our non-resident investors may be taxed under SAT Circular 698 and may be required to expend valuable resources to comply with SAT Circular 698 or to establish that we or our non-resident investors should not be taxed under SAT Circular 698, which may have an adverse effect on our financial condition and results of operations or such non-resident investors’ investment in us.

Labor laws in the PRC may adversely affect our results of operations.

On June 29, 2007, the PRC government promulgated the Labor Contract Law of the PRC, or the Labor Contract Law, which became effective on January 1, 2008. The Labor Contract Law imposes greater liabilities on employers and significantly impacts the cost of an employer’s decision to reduce its workforce. Further, it requires certain terminations to be based upon seniority and not merit. In the event we decide to significantly change or decrease our workforce, the Labor Contract Law could adversely affect our ability to enact such changes in a manner that is most advantageous to our business or in a timely and cost-effective manner, thus materially and adversely affecting our financial condition and results of operations.

We face risks related to health epidemics and other outbreaks.

Adverse public health epidemics or pandemics could disrupt business and the economics of the PRC and other countries where we do business. From December 2002 to June 2003, China and other countries experienced an outbreak of a highly contagious form of atypical pneumonia now known as severe acute respiratory syndrome, or SARS. Some Asian countries, including China, encountered incidents of the H5N1 strain of bird flu, or avian flu in 2007 and early 2008. In 2009, there were outbreaks of swine flu, caused by H1N1 virus, in certain regions of the world, including China. Any future outbreak of SARS, avian flu, swine flu or other similar adverse public developments may, among other things, significantly disrupt our business, including limiting our ability to travel or ship our products within or outside China and forcing us to temporary close our manufacturing facilities. Furthermore, an outbreak may severely restrict the level of economic activity in affected areas, which may in turn materially and adversely affect our financial condition and results of operations. We have not adopted any written preventive measures or contingency plans to combat any future outbreak of swine flu, avian flu, SARS or any other epidemic.

Risks Related to Our Ordinary Shares and ADSs

The market price of our ADSs may be volatile.

The market price of our ADSs experienced, and may continue to experience, significant volatility. For the period from December 20, 2006 to June 2, 2011, the trading price of our ADSs on the Nasdaq Global Market has ranged from a low of US$2.30 per ADS to a high of US$37.64 per ADS.

Numerous factors, including many over which we have no control, may have a significant impact on the market price of our ADSs, including, among other things:

•		announcements of technological or competitive developments;
•		regulatory developments in our target markets affecting us, our customers or our competitors;
•		announcements regarding patent litigation or the issuance of patents to us or our competitors;
•		announcements of studies and reports relating to the conversion efficiencies of our products or those of our competitors;
•		actual or anticipated fluctuations in our quarterly operating results;
•		changes in financial estimates or other material comments by securities analysts relating to us, our competitors or our industry in general;
•		announcements by other companies in our industry relating to their operations, strategic initiatives, financial condition or financial performance or to our industry in general;
•		announcements of acquisitions or consolidations involving industry competitors or industry suppliers;
•		changes in the economic performance or market valuations of other PV technology companies;
•		addition or departure of our executive officers and key research personnel; and
•		sales or perceived sales of additional ordinary shares or ADSs.

In addition, the stock market in recent years has experienced extreme price and trading volume fluctuations that often have been unrelated or disproportionate to the operating performance of individual companies. These broad market fluctuations may adversely affect the price of our ADSs, regardless of our operating performance.

Our articles of association contain anti-takeover provisions that could have a material adverse effect on the rights of holders of our ordinary shares and ADSs.

Our amended and restated articles of association limit the ability of others to acquire control of our company or cause us to engage in change-of-control transactions. These provisions could have the effect of depriving our shareholders of an opportunity to sell their shares at a premium over prevailing market prices by discouraging third parties from seeking to obtain control of our company in a tender offer or similar transaction. For example, our board of directors has the authority, without further action by our shareholders, to issue preferred shares in one or more series and to fix their designations, powers, preferences, privileges, and relative participating, optional or special rights and the qualifications, limitations or restrictions, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences, any or all of which may be greater than the rights associated with our ordinary shares, in the form of ADS or otherwise. Preferred shares could be issued quickly with terms calculated to delay or prevent a change in control of our company or make removal of management more difficult. If our board of directors decides to issue preferred shares, the price of our ADSs may fall and the voting and other rights of the holders of our ordinary shares and ADSs may be materially and adversely affected.

Holders of ADSs have fewer rights than shareholders and must act through the depositary to exercise those rights.

Holders of ADSs do not have the same rights as our shareholders and may only exercise the voting rights with respect to the underlying ordinary shares in accordance with the provisions of the deposit agreement. Under our amended and restated articles of association, the minimum notice period required to convene an annual general meeting or any extraordinary general meeting calling for the passing of a special resolution is 20 days and the minimum notice period required to convene any other extraordinary general meeting is 14 days. When a general meeting is convened, you may not receive sufficient notice of a shareholders’ meeting to permit you to withdraw your ordinary shares to allow you to cast your vote with respect to any specific matter. If requested in writing by us, the depositary will mail a notice of such a meeting to you. In addition, the depositary and its agents may not be able to send voting instructions to you or carry out your voting instructions in a timely manner. We will make all reasonable efforts to cause the depositary to extend voting rights to you in a timely manner, but you may not receive the voting materials in time to ensure that you can instruct the depositary to vote your ADSs. Furthermore, the depositary and its agents will not be responsible for any failure to carry out any instructions to vote, for the manner in which any vote is cast or for the effect of any such vote. As a result, you may not be able to exercise your right to vote and you may lack recourse if your ADSs are not voted as you requested. In addition, in your capacity as an ADS holder, you will not be able to call a shareholders’ meeting.

You may be subject to limitations on transfers of your ADSs.

Your ADSs are transferable on the books of the depositary. However, the depositary may close its transfer books at any time or from time to time when it deems expedient in connection with the performance of its duties. In addition, the depositary may refuse to deliver, transfer or register transfers of ADSs generally when our books or the books of the depositary are closed, or at any time if we or the depositary deem it advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason.

Your right to participate in any future rights offerings may be limited, which may cause dilution to your holdings, and you may not receive distributions with respect to the underlying ordinary shares if it is impractical to make them available to you.

We may from time to time distribute rights to our shareholders, including rights to acquire our securities. However, we cannot make rights available to you in the United States unless we register the rights and the securities to which the rights relate under the Securities Act or an exemption from the registration requirements is available. Also, under the deposit agreement, the depositary will not make rights available to you unless the distribution to ADS holders of both the rights and any related securities are either registered under the Securities Act, or exempted from registration under the Securities Act. We are under no obligation to file a registration statement with respect to any such rights or securities or to endeavor to cause such a registration statement to be declared effective. Moreover, we may not be able to establish an exemption from registration under the Securities Act. Accordingly, in the event we conduct any rights offering in the future, the depositary may not make such rights available to you or may dispose of such rights and make the net proceeds available to you. As a result, you may be unable to participate in our rights offerings and may experience dilution in your holdings.

In addition, the depositary of our ADSs has agreed to pay to you the cash dividends or other distributions it or the custodian receives on our ordinary shares or other deposited securities after deducting its fees and expenses. You will receive these distributions in proportion to the number of ordinary shares your ADSs represent. However, the depositary may, at its discretion, decide that it is inequitable or impractical to make a distribution available to any holders of ADSs. As a result, the depositary may decide not to make the distribution and you will not receive such distribution.

We are a Cayman Islands company and, because judicial precedent regarding the rights of shareholders is more limited under Cayman Islands law than under U.S. law, you may have less protection for your shareholder rights than you would under U.S. law.

Our corporate affairs are governed by our amended and restated memorandum and articles of association as may be amended from time to time, the Cayman Islands Companies Law (as amended) and the common law of the Cayman Islands. The rights of shareholders to take action against the directors, actions by minority shareholders and the fiduciary responsibilities of our directors to us under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as that from English common law, which has persuasive, but not binding, authority on a court in the Cayman Islands. The rights of our shareholders and the fiduciary responsibilities of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands has a less developed body of securities laws than the United States. In addition, Cayman Islands companies may not have standing to initiate a shareholder derivative action in a federal court of the United States.

There is also uncertainty as to whether the courts of the Cayman Islands would:

•		recognize or enforce against us or our directors, judgments of courts of the United States based on certain civil liability provisions of U.S. securities laws; and
•		entertain original actions brought in the Cayman Islands, based on certain civil liability provisions of U.S. securities laws that are penal in nature.

There is no statutory recognition in the Cayman Islands of judgments obtained in the United States, although the courts of the Cayman Islands will generally recognize and enforce a non-penal judgment of a foreign court of competent jurisdiction without retrial on the merits.

As a result of all of the above, our public shareholders may have more difficulty in protecting their interests in the face of actions taken against management, members of the board of directors or controlling shareholders than they would as shareholders of a U.S. public company.

You may have difficulty enforcing judgments obtained against us.

We are a Cayman Islands company and substantially all of our assets are located outside of the United States. Substantially all of our current operations are conducted in the PRC. In addition, most of our directors and officers are nationals and residents of countries other than the United States. A substantial portion of the assets of these persons are located outside the United States. As a result, it may be difficult for you to effect service of process within the United States upon these persons. It may also be difficult for you to enforce in U.S. courts judgments obtained in U.S. courts based on the civil liability provisions of the U.S. federal securities laws against us and our officers and directors, most of whom are not residents in the United States and the substantial majority of whose assets are located outside of the United States. In addition, there is uncertainty as to whether the courts of the Cayman Islands or the PRC would recognize or enforce judgments of U.S. courts based on certain civil liability provisions of U.S. securities laws.

ITEM 4 INFORMATION ON THE COMPANY

A. History and Development of the Company

We commenced operations through SolarOne Qidong, formerly known as Jiangsu Linyang Solarfun Co., Ltd., in August 2004. SolarOne Qidong was a 68%-owned subsidiary of Jiangsu Linyang Electronics Co., Ltd., or Linyang Electronics, at the time of its establishment on August 27, 2004. Linyang Electronics is one of the leading electricity-measuring instrument manufacturers in China. In anticipation of our initial public offering, we incorporated Hanwha SolarOne, formerly known was Solarfun Power Holdings Co., Ltd., in the Cayman Islands on May 12, 2006 as our listing vehicle. To enable us to raise equity capital from investors outside of China, we established a holding company structure by incorporating Hanwha SolarOne Investment Holding Ltd., formerly known as Linyang Solar Power Investment Holding Ltd., or SolarOne BVI, in the British Virgin Islands on May 17, 2006. SolarOne BVI is wholly owned by Hanwha SolarOne. SolarOne BVI purchased all of the equity interests in SolarOne Qidong on June 2, 2006. On May 16, 2007, SolarOne BVI established a wholly owned subsidiary, Hanwha SolarOne Hong Kong Limited, formerly known as Solarfun Power Hong Kong Limited, or SolarOne Hong Kong. In March 2006, April 2006 and April 2007, we established three majority-owned or wholly owned subsidiaries in China, Shanghai Linyang Solar Technology Co., Ltd., or Solar Shanghai, Sichuan Leshan Jiayang New Energy Co., Ltd., or Sichuan Jiayang, and Hanwha Solar Engineering Research and Development Center Co., Ltd., formerly known as Nantong Linyang Solarfun Engineering Research and Development Center Co., Ltd., or Solar R&D, respectively, to expand our business into new markets and sectors. We acquired a 52% interest in Hanwha SolarOne Technology Co., Ltd., formerly known as Jiangsu Yangguang Solar Technology Co., Ltd., or SolarOne Technology, in July 2007 and acquired the remaining 48% in August 2008. In September 2007, we

established a wholly owned subsidiary, Hanwha SolarOne U.S.A. Inc., formerly known as Solarfun Power U.S.A. Inc., or SolarOne U.S.A., as part of our plan to enter the United States market. On November 30, 2007, SolarOne BVI transferred all of the equity interests in SolarOne Qidong to SolarOne Hong Kong, for a consideration of US$199.0 million. In February 2008, we established a wholly owned subsidiary, Hanwha SolarOne Deutschland GmbH, formerly known as Solarfun Power Deutschland GmbH, or SolarOne Deutschland, in Germany to sell solar products in the European markets. We liquidated Sichuan Jiayang, one of our subsidiaries which historically has had limited operations, in July 2008. In November 2009, we acquired the remaining 17% equity interest in Solar Shanghai and Solar Shanghai became our wholly owned subsidiary after the completion of this transaction. We established Hanwha Solar Electric Power Engineering Co., Ltd., formerly known as Jiangsu Linyang Solar Electric Power Engineering Co., Ltd., or Solar Engineering, in May 2010 under SolarOne Qidong to engage in the solar power project business.

In September 2010, we issued and sold to Hanwha Solar Holdings Co., Ltd., or Hanwha Solar, 36,455,089 ordinary shares for an aggregate sale price of US$78.2 million. Concurrently with the closing of this offering, we issued 30,672,689 ordinary shares to Hanwha Solar at par value of the ordinary shares and subsequently an additional 14,407,330 ordinary shares at par value, which shares shall remain outstanding so long as and to the extent that the 9,019,611 ADSs we issued to facilitate our convertible bond offering in January 2008 remain outstanding. At the same time, Hanwha Solar completed the acquisitions from Good Energies II LP and Yonghua Solar Power Investment Holding Ltd., the company owned by Mr. Yonghua Lu, our former chairman, of a total of 120,407,700 ordinary shares and 1,281,011 ADSs of our company, representing all of the ordinary shares and ADSs held by them. Hanwha Solar, a company that engages in solar business, is a wholly-owned subsidiary of Hanwha Chemical Corporation, a leading chemical producer publicly traded on the Korea Exchange whose principal activities are the production of CA, PE and PVC, products.

In November 2010, we issued and sold 9,200,000 ADSs with an aggregate sale price of US$82.8 million. In order for Hanwha Solar to maintain after this offering the same level of beneficial ownership in our company as before this offering, we also issued and sold to Hanwha Solar 45,981,604 ordinary shares for an aggregate sale price of US$82.8 million. As a result of these transactions, Hanwha Solar owns an approximately 49.8% equity interest in our company. We changed our name from “Solarfun Power Holdings Co., Ltd.” to “Hanwha SolarOne Co., Ltd.” on December 20, 2010 and our ticker from “SOLF” to “HSOL” on February 15, 2011. In April 2011, we established Nantong Hanwha Import & Export Co., Ltd., or Nantong Hanwha I&E, under SolarOne Qidong to engage in import and export of PV products and technology and Hanwha SolarOne (Nantong) Co., Ltd., or SolarOne Nantong, under SolarOne Hong Kong to develop, manufacture and sell PV products.

We made capital expenditures of RMB1,169.0 million, RMB324.7 million and RMB670.8 million (US$101.6 million) in 2008, 2009 and 2010, respectively, all of which related primarily to the purchases of manufacturing equipment and facility construction costs. Based on the current market conditions, we expect to incur capital expenditures of US$450.0 million for 2011, which will be used primarily for purchasing manufacturing equipment and building production facilities in Nantong, Qidong and Lianyungang, Jiangsu Province. We plan to fund the balance of our capital expenditure requirements for 2011 with cash from operations, additional bank borrowings, and other forms of financing, if necessary.

B. Business Overview

Overview

We are a vertically integrated manufacturer of silicon ingots, silicon wafers, PV cells and PV modules in China. We manufacture a variety of silicon ingots, silicon wafers, PV cells and PV modules using advanced manufacturing process technologies that have helped us to rapidly increase our operational efficiency. We also provide PV module processing services. We sell PV cells and PV modules both directly to system integrators and through third party distributors. In 2010, we sold our products to over 50 customers, mostly in Germany, Italy, Australia, the United States, the Czech Republic, Spain and China. We conduct our business in China through our operating subsidiary.

As of April 30, 2010, we had 1,000 MW of annual PV module production capacity and 700 MW of annual PV cell production capacity. In addition, we have achieved improvements in process technology and product quality since we commenced our commercial production in November 2005. Our monocrystalline and multicrystalline PV cells achieved conversion efficiency rates in the ranges of 17.3% to 18.3% and 15.5% to 17.0%, respectively, in 2010. In addition, we had 415 MW of annual ingot production capacity and 500 MW of annual wire sawing capacity as of April 30, 2010. We plan to expand our PV module production capacity from 1,000 MW to 1,500 MW, PV cell production capacity from 700 MW to 1,300 MW, ingot production capacity from 415 MW to 1,000 MW and wire sawing capacity from 500 MW to 1,000 MW by the end of 2011.

Our net revenues decreased from RMB4,949.1 million in 2008 to RMB3,778.3 million in 2009, but increased to RMB7,527.0 million (US$1,140.5 million) in 2010. Our consolidated net income increased from a net loss of RMB265.9 million in 2008 to a net loss of RMB144.9 million in 2009, and net income of RMB757.4 million (US$114.8 million) in 2010.

Our Products and Services

Our products primarily include silicon ingots, silicon wafers, PV cells and PV modules. Since 2009, substantially all of the ingots, wafers and PV cells we produced have been used for our own PV module production. We also provide PV module processing services.

Our Products

PV Cells

A PV cell is a semiconductor device that converts sunlight into electricity by a process known as the photovoltaic effect. The following table sets forth the specifications of two types of PV cells we currently produce:

		Dimensions		Conversion		Thickness		Maximum
PV Cell Type		(mm×mm)		Efficiency (%)		(EM)		Power (W)
Monocrystalline silicon cell		125 × 125		17.3 – 18.3%		180 – 200		2.68 – 2.84
		156 × 156		17.3 – 18.3%		180 – 200		4.13 – 4.37
Multicrystalline silicon cell		156 × 156		15.5 – 17.0%		180 – 200		3.77 – 4.13

The key technical efficiency measurement of PV cells is the conversion efficiency rate. Assuming other things being the same, the higher the conversion efficiency rate, the lower the production cost of PV modules per watt because more power can be incorporated into a given size package. Our monocrystalline and multicrystalline PV cells achieved conversion efficiency rates in the ranges of 17.3% to 18.3% and 15.5% to 17.0%, respectively, in 2010.

We are now able to process wafers as thin as 180 microns. In order to further lower our production costs, we intend to focus on producing PV cells with decreasing thickness levels.

In 2009, we introduced “ECLIPSE,” a new line of PV cells and modules with reduced light induced degradation. This type of products reduces the impurity concentration in cells, thereby reducing light induced degradation to approximately 1% from 2% to 3%, or less than 2 W compared to approximately 4 W to 5 W for a 180 W module equipped with standard cells. This results in an increase in electricity generation of approximately 1% to 2% over the long term when compared with standard modules.

In an effort to further improve our technological capability, we plan to adopt selective emitter technology in our existing cell production lines with an annual production capacity of 160 MW in the second half of 2011.

PV Modules

A PV module is an assembly of PV cells that have been electrically interconnected and laminated in a durable and weather-proof package. We have been selling a wide range of PV modules, currently ranging from 5 W to 295 W in power output specification, made primarily from the PV cells we manufacture. We are developing modules with higher power to meet the rising demand for on-grid configurations. The majority of the PV modules we currently offer to our customers range in power between 185 W and 285 W. We sell approximately 51% of our PV modules under our proprietary “Solarfun” and “SolarOne” brand names, and approximately 49%, respectively, of our PV modules under the brand names of our customers.

The following table sets forth the types of PV modules we manufacture with the specifications indicated:

		Dimensions				Weight
PV Module Manufactured with:		(mm)				(Kg)				Power (W)
Monocrystalline silicon			1580 × 808 × 45				14			160–195
			1494 × 1000 × 45				17			170–225
			1652 × 1000 × 50				21			200–255
			1966 × 1000 × 50				26			250–300
Multicrystalline silicon			1580 × 808 × 45				14			160–195
			1494 × 1000 × 45				17			170–225
			1652 × 1000 × 50				21			200–255
			1966 × 1000 × 50				26			250–300

We believe our PV cells and modules are competitive with other products in the PV market in terms of efficiency and quality. We expect to continue improving the conversion efficiency and power, and reducing the thickness, of our solar products as we continue to devote significant financial and human resources in our various research and development programs.

Ingots and Wafers

We also manufacture ingots through SolarOne Technology, an ingot plant that commenced operations in October 2007. As of April 30, 2011, we operated 40 monocrystalline ingot production furnaces and 52 multicrystalline ingot production furnaces, with up to 415 MW of annual manufacturing capacity. The ingots manufactured by SolarOne Technology are generally used for our manufacture of wafers.

In order to further integrate our production upstream, SolarOne Qidong has purchased and installed 66 units of wire saws equipment, which can be used to slice ingots into wafers, and achieved annual wire sawing capacity of 500 MW. The wafers manufactured by SolarOne Qidong are generally used for our manufacture of PV cells and PV modules.

Our Services

We provide PV module processing services to convert PV cells into PV modules on behalf of a third party. For these PV module processing services, we “purchase” PV cells from a customer and at the same time agree to “sell” a specified quantity of PV modules back to the same customer. The quantity of PV modules sold back to the customer under this processing arrangement is consistent with the amount of PV cells purchased from the customer after factoring in conversion efficiency. We record the amount of revenue from these processing transactions based on the amount received for PV modules sold less the amount paid for the PV cells purchased from the customer. The production costs incurred related to providing the module processing services are recorded within our cost of revenues.

In response to the rapidly evolving conditions in the PV industry, we started to expand our business downstream to provide system integration services in 2010. Our PV system integration services may include services such as engineering, procurement of permits and equipment, construction management, monitoring and maintenance. We offer PV system integration services through our subsidiary, Hanwha Solar Electric Power Engineering Co., Ltd., or Solar Engineering.

Raw Materials Supply Management

Manufacturing of our solar products requires reliable supplies of various raw materials, including silicon wafers, ethylene vinyl acetate, triphenyltin, tempered glass, connecting bands, welding bands, silica gel, aluminum alloy and junction boxes. We seek to diversify the supply sources of raw materials and have not in the past experienced any material disruption of our manufacturing process due to insufficient supply of raw materials. The aggregate costs attributable to our five largest raw materials suppliers in 2008, 2009 and 2010 were 42.0%, 51.6% and 40.0%, respectively, of our total raw material purchases.

We maintain different inventory levels of our raw materials, depending on the type of product and the lead time required to obtain additional supplies. We seek to maintain reasonable inventory levels that achieve a balance between our efforts to reduce our storage costs and optimize working capital on one hand, and the need to ensure that we have access to adequate supplies on the other. As of December 31, 2008, 2009 and 2010, we had RMB488.6 million, RMB277.6 million and RMB459.5 million (US$69.6 million), respectively, of raw materials in inventory.

Silicon-based Raw Materials

Among the various raw materials required for our manufacturing process, silicon wafers are the most important for producing PV cells. A silicon wafer is a flat piece of crystalline silicon that can be processed into a PV cell. Silicon wafers used for PV cell production are generally classified into two different types: monocrystalline and multicrystalline silicon wafers. Compared to monocrystalline silicon wafers, multicrystalline silicon wafers have a lower conversion rate but are less expensive. We currently use 6-inch, 6.5-inch, 7-inch and 8-inch wafers in our production. PV cells can be manufactured on our production lines using both types of silicon wafers with certain temporary adjustments to the production line. We believe that the ability to manufacture using both types of silicon wafers provides us with greater flexibility in procuring raw materials, especially during periods of silicon supply shortages.

We purchase all of our silicon and approximately 40% of our ingots and silicon wafers from third-party suppliers. We purchase silicon, ingots and wafers from both domestic and overseas suppliers, with the majority of our purchases being made in the domestic market. We use ingots manufactured by SolarOne Technology, one of our wholly owned subsidiaries, in our manufacturing process. Currently, our principal silicon suppliers include Samsung Corporation, Ya An Yongwang Silicon Co., Ltd., or Yongwang, GCL Silicon Technology Holdings Limited, or GCL, Solar Power Industries, or SPI, and Chongqing Daqo New Energy Co., Ltd., or Daqo.

We procure a significant portion of our silicon and silicon wafers from suppliers under multi-year supply agreements. Each of our existing multi-year supply agreements provides for adjustments in subsequent years to reflect changes in market conditions or through mutual agreement, except one agreement we entered into in 2010 where the price is pre-determined without any future adjustment. We procure our remaining silicon and silicon wafer supplies from short-term supply agreements and the spot market.

Prior to mid-2008, there was an industry-wide shortage of silicon and silicon wafers, which resulted in significant increases in the prices of these raw materials. To secure an adequate and timely supply of silicon and silicon wafers during the earlier periods of supply shortage, we have established supply arrangements with a number of silicon and silicon wafer suppliers, including a 11-year supply contract with Hoku, a seven-year supply contract with a non-PRC supplier and supply contracts with LDK and E-mei. Since the fourth quarter of 2008, the market prices for silicon and silicon wafers have been decreasing significantly. Spot market prices of silicon and silicon wafers have fallen below the prices we have contracted for with our long-term suppliers and continued to decline in 2009. Due to the significant decrease in prices of silicon and silicon wafers, we re-negotiated all of our multi-year supply agreements that were in place as of December 31, 2009, except the agreement with LDK. After re-negotiation, the terms of price of such multi-year agreements were generally subject to review either periodically or upon significant changes in prices on the spot market. See “Item 3.D. Risk Factors — Risks Related to Our Company and Our Industry — Our ability to adjust our raw material costs may be limited as a result of our entering into multi-year supply agreements with many of our silicon and silicon wafer suppliers, and it may be difficult for us to respond in a timely manner to rapidly changing market condition, which could materially and adversely affect our cost of revenues and profitability.”

We acquired a 52% equity interest in SolarOne Technology in July 2007 and acquired the remaining 48% equity interest in August 2008. The key raw material for our production of ingots is polysilicon. We purchase polysilicon primarily from GCL, Yongwang and Daqo.

Other Raw Materials

In addition to silicon and silicon wafers, we use a variety of other raw materials for our production. As part of our continuing cost control efforts, we source a significant portion of these raw materials locally. We believe that our policy to use primarily locally sourced raw materials and our continuing price negotiations with our local raw material suppliers have made a significant contribution to our profitability since we commenced operations in 2004. The use of locally sourced raw materials also shortens our lead order time and provides us with better access to technical and other support from our suppliers.

Production

We manufacture our wafers, PV cells and PV modules through SolarOne Qidong, our wholly owned PRC subsidiary, with facilities occupying a gross floor area of 79,138 square meters in Qidong, Jiangsu Province, China. We commenced commercial production on our first PV cell production line in November 2005 and had 1,000 MW of annual PV module capacity and 700 MW of annual PV cell production capacity as of April 30, 2010. We had 54 multicrystalline silicon wafer wire saws and 12 monocrystalline silicon wafer wire saws, with a total annual manufacturing capacity of 500 MW as of April 30, 2010. We produce multicrystalline and monocrystalline silicon wafers with a dimension of 156 mm x 156 mm and 125 mm x 125 mm, respectively. The thickness of our silicon wafers is between 180 and 220 microns.

We manufacture our silicon ingots through SolarOne Technology, one of our wholly owned subsidiaries, with facilities occupying a gross floor area of approximately 33,730 square meters in Lianyungang, Jiangsu Province, China. SolarOne Technology commenced its operations in October 2007. As of April 30, 2010, we operated 40 monocrystalline ingot production furnaces and 52 multicrystalline ingot production furnaces, with up to 415 MW of annual manufacturing capacity.

We were able to lower our initial investment by purchasing key equipment with more sophisticated technology from overseas suppliers while procuring other equipment domestically. We plan our production on an annual, semi-annual and monthly basis in accordance with anticipated demand and make weekly adjustments to our production schedule based on actual orders received.

Production Process

The following diagram shows the general production stages for our PV cells:

The following diagram shows the production procedures for our PV modules:

The following diagram shows the general production stages for our ingots:

Quality Control and Certifications

Our finished PV cells and PV modules are inspected and tested according to standardized procedures. In addition, we have established multiple inspection points at key production stages to identify product defects during the production process. Unfinished products that are found to be below standard are repaired or replaced. Our quality control procedures also include raw material quality inspection and testing. Moreover, we provide regular training and specific guidelines to our operators to ensure that production processes meet our quality inspection and other quality control procedures.

We maintain several certifications for our quality control procedures, which demonstrate our compliance with international and domestic operating standards. We believe that our quality control procedures are enhanced by the use of sophisticated production system designs and a high degree of automation in our production process. The certifications we currently maintain include ISO 9001:2000 quality system certification for the process of design, production and sale of our PV modules, the TÜV certification for our PV modules and the UL certification. The TÜV certification is issued by an independent approval agency in Germany to certify our PV modules are qualified for IEC 61215 and IEC 61730 safety test standards and consistent production quality inspections are performed periodically. Maintaining this certification has greatly enhanced our sales in European countries. We obtained UL certification issued by Underwriters Laboratories Inc., an independent product-safety testing and certification organization in the United States, which will enable us to sell our products to customers in the United States. Furthermore, in the United States, our modules have been certified by the California Energy Commission, the state’s primary energy policy and planning agency, and the Florida Solar Energy Center, a regional energy research and certification organization of the United States. We also obtained a certification issued by KEMCO, an independent product-safety testing and certification organization in Korea, which will enable us to sell our products to customers in Korea.

Capacity Expansion and Technology Upgrade Plans

As of April 30, 2010, we had 1,000 MW of annual PV module production capacity and 700 MW of annual PV cell production capacity in commercial operation. We plan to expand our PV module production capacity from 1,000 MW to 1,500 MW by the end of 2011 and our PV cell production capacity from 700 MW to 1,300 MW by the end of 2011. We also plan to expand our annual ingot production capacity from 415 MW to 1,000 MW and annual wire sawing capacity from 500 MW to 1,000 MW by the end of 2011. We are constructing manufacturing buildings in Qidong and Lianyungang, Jiangsu Province to accommodate our planned expansion of production capacities. In December 2010, we entered into an investment letter of intent with Nantong Economic and Technological Development Zone to build cell and module production facilities with an annual production capacity of 2 GW in Nantong, Jiangsu Province. We plan to complete the first phase of the cell and module production facilities with an annual production capacity of 1 GW in three years. As one of our key strategies, we intend to continuously improve the conversion efficiency of our solar products. We plan to adopt selective emitter technology in our existing cell production lines with an annual production capacity of 160 MW in the second half of 2011.

The expansion plans and capacities indicated above are indicative only of our current plans and are subject to change due to a number of factors, including, among others, market conditions and demand for our products. Based on the current market conditions, we expect to incur capital expenditures of US$450.0 million for 2011, which will be used primarily for purchasing manufacturing equipment and building production facilities in Nantong, Qidong and Lianyungang, Jiangsu Province. We plan to fund the balance of our capital expenditure requirements for 2011 with cash from operations, additional bank borrowings, and other forms of financing, if necessary.

Sales and Distribution

We sell our PV modules through distributors and directly to system integrators. Our customers include international solar power system integrators and distributors. Our system integrator customers provide value-added services and typically design and sell complete systems that use our PV modules.

Customers that accounted for a significant portion of our total net revenues in 2010 included Qcells SE, Rusol, Conergy, Isolux Ingenieria SA, Meridian Solarpark XXXIII GMBH, Schüco, Scatec and Nobility Solar Projects. Our five largest customers accounted for an aggregate of 53.2%, 65.3% and 51.9% of our net revenues in 2008, 2009 and 2010, respectively. Our largest customer in 2008, 2009 and 2010 accounted for 22.2%, 41.4% and 33.6% of our net revenues of the respective year.

We have established two wholly owned subsidiaries, namely SolarOne U.S.A. and SolarOne Deutschland, to market our products and provide customer support and service in these markets. The following table sets forth our net revenues by geographic region, based on the location that our invoices are sent to, and the percentage contribution of each of these regions to our net revenues, for the periods indicated:

In 2010, we shipped our products to over 40 customers. In 2008, 2009 and 2010, customers accounting for 10.0% or more of our net revenues collectively accounted for 22.2%, 41.4% and 33.6% of our net revenues, respectively, and sales to our largest customer accounted for 22.2%, 41.4% and 33.6% of our net revenues, respectively. We seek to further diversify our geographic presence and customer base in order to achieve a balanced and sustainable growth.

Warranty

We provide a two to five-year warranty for technical defects and a 10-year limited warranty against declines of greater than 10%, and a 20 to 25-year limited warranty against declines of greater than 20%, in the initial power generation capacity of our PV modules. After-sales services for our PV modules and solar application systems covered by warranties are provided by our international customer support team. We provided RMB46.6 million, RMB33.7 million and RMB67.6 million (US$10.2 million) in warranty costs for the two to five-year warranty against technical defects in 2008, 2009 and 2010, respectively.

Intellectual Property and Proprietary Rights

Our intellectual property is an essential element of our business. We rely on patent, copyright, trademark, trade secret and other intellectual property law, as well as non-competition and confidentiality agreements with our employees, suppliers, business partners and others, to protect our intellectual property rights.

As of April 30, 2011, we had been granted 20 patents by the State Intellectual Property Office of China and had 14 patent applications pending in China. Our issued patents and pending patent applications relate primarily to process technologies for manufacturing PV cells.

We have registered “Solarfun,” our trademark for our PV cells and modules, with the China Trademark Office and the International Bureau of the World Intellectual Property Organization, which allow us to use this trademark in China, Singapore and the United States.

On January 10, 2011, we filed the application to register our new trademark, “Hanwha SolarOne”, with the International Bureau for Intellectual Property. We started to use the new trademark in May 2011.

We rely on trade secret protection and confidentiality agreements to protect our proprietary information and know-how. Our management and each of our research and development personnel have entered into a standard annual employment contract, which includes confidentiality undertakings and an acknowledgement and agreement that all inventions, designs, trade secrets, works of authorship, developments and other processes generated by them on our behalf are our property, and assigns to us any ownership rights that they may claim in those works. Our supply contracts with our customers also typically include confidentiality undertakings. Despite these precautions, it may be possible for third parties to obtain and use intellectual property that we own or license without consent. Unauthorized use of our intellectual property by third parties, and the expenses incurred in protecting our intellectual property rights, may materially and adversely affect our business, financial condition, results of operations and prospects. See “Item 3.D. Risk Factors — Risks Related to Our Company and Our Industry — Our failure to protect our intellectual property rights may undermine our competitive position, and litigation to protect our intellectual property rights may be costly.”

Competition

Due to various government incentive programs implemented in China, Europe, the United States, Japan and other countries in recent years, the global PV market has been rapidly evolving and has become highly competitive. In particular, a large number of manufacturers have entered the solar market.

Our main overseas competitors are, among others, Mitsubishi Electric Corporation, Sharp Corporation and Sunpower Corporation. Our primary competitors in China include Suntech Power Holdings Co., Ltd., Trina Solar Ltd., Yingli Green Energy Holdings Co., Ltd. and Canadian Solar Inc. We compete primarily on the basis of the power efficiency, quality, performance and appearance of our products, price, strength of supply chain and distribution network, after-sales service and brand image. Many of our competitors have longer operating histories and significantly greater financial or technological resources than we do and enjoy greater brand recognition. Some of our competitors are vertically integrated and produce upstream silicon and silicon wafers, mid-stream PV cells and modules and downstream solar application systems, which provide them with greater synergies to achieve lower production costs. During periods when there was a supply shortage of silicon and silicon wafers, we competed intensely with our competitors in obtaining adequate supplies of silicon and silicon wafers.

Moreover, many of our competitors are developing next-generation products based on new PV technologies, including amorphous silicon, transparent conductive oxide thin film, carbon material and nano-crystalline technologies, which, if successful, will compete with the crystalline silicon technology we currently use in our manufacturing processes. Through our research collaborations, we are also seeking to develop new technologies and products. If we fail to develop new technologies and products in a timely manner, we may lose our competitive advantage.

We, like other solar energy companies, also face competition from traditional non-solar energy industries, such as the petroleum and coal industries. The production cost per watt of solar energy is significantly higher than other types of energy. As a result, we cannot assure you that solar energy will be able to compete with other energy industries, especially if there is a reduction or termination of government incentives and other forms of support.

Environmental Matters

Our manufacturing processes generate noise, waste water, gaseous wastes and other industrial wastes. Our manufacturing facilities are subject to various pollution control regulations with respect to noise and air pollution and the disposal of waste and hazardous materials. We are also subject to periodic inspections by local environmental protection authorities. We have established a pollution control system and installed various equipment to process and dispose of our industrial waste and hazardous materials. We believe that we have obtained all requisite environmental permits and approvals to conduct our business. We also maintain an ISO 14001 environmental management system certification, which is issued by International Organization for Standardization to demonstrate our compliance with international environmental standards. We have not been subject to any material proceedings or fines for environmental violations.

Insurance

We maintain property insurance for our equipment, automobiles, facilities and inventory. A significant portion of our fixed assets are covered by these insurance policies. We also maintain business interruption insurance, product liability insurance, product quality guarantee insurance and export credit insurance. We believe our insurance coverage is customary and standard for companies of comparable size in comparable industries in China. However, our existing insurance policies may not be sufficient to insulate us from all losses and liabilities that we may incur.

Regulation

This section sets forth a summary of the most significant regulations or requirements that affect our business activities in China or our shareholders’ right to receive dividends and other distributions from us.

Renewable Energy Law and Other Government Directives

In February 2005, China’s Standing Committee of National People’s Congress, or SCNPC, enacted the Renewable Energy Law, which has become effective on January 1, 2006. On December 26, 2009, the Renewable Energy law was amended by SCNPC. The Renewable Energy law, as amended, sets forth the national policy to encourage and support the development and use of solar and other renewable energy and the use of on-grid generation.

The law also sets forth the national policy to encourage the installation and use of solar energy water-heating systems, solar energy heating and cooling systems, solar photovoltaic systems and other solar energy utilization systems. In addition, the law provides financial incentives, such as national funding, preferential loans and tax preferences for the development of renewable energy projects.

China’s Ministry of Construction also issued a directive in June 2005 that sought to expand the use of solar energy in residential and commercial buildings and encouraged the increased application of solar energy in different townships. In addition, China’s State Council promulgated a directive in July 2005 that set forth principles with regard to the conservation of energy resources and the development and use of solar energy in the western part of China, which has not been covered by electricity transmission grids and rural areas.

In January 2006, the NDRC issued two implementing rules relating to the Renewable Energy Law: (1) the Trial Measures on the Administration over the Pricing and Cost Allocation of Renewable Energy Power Generation and (2) the Administrative Regulations Relating to the Renewable Energy Power Generation. These implementing rules, among other things, set forth general policies for the pricing of on-grid power generated by solar and other renewable energy. In addition, the PRC Ministry of Finance issued the Provisional Measures for Administration of Specific Funds for Development of Renewable Energy in June 2006, which provides that the PRC government will establish a fund specifically for the purpose of supporting the development of the renewable energy industry, including the PV industry.

On March 3, 2008, the NDRC issued the “11th Five-Year Plan for the Development of Energy Resources,” which announced the PRC government’s support for the development of renewable energy resources in China, including solar power.

On March 23, 2009, China’s Ministry of Finance promulgated the Interim Measures for Administration of Government Subsidy Funds for Application of Solar Photovoltaic Technology in Building Construction, or the Interim Measures, to support the demonstration and the promotion of solar photovoltaic application in China. Local governments are encouraged to issue and implement supporting policies for the development of solar photovoltaic technology. Under these Interim Measures, the Ministry of Finance provides subsidies for projects with individual solar installations that are greater than 50 kilowatt-peak in size and have more than 16% conversion efficiency for monocrystalline PV products, more than 14% conversion efficiency for multicrystalline PV products and more than 6% conversion efficiency for amorphous silicon PV products, and gives priority support to solar PV technology integrated into building construction, grid-connected PV building applications and some public PV building applications such as schools, hospitals and offices. For 2009, the standard subsidy is set at RMB20 per watt in principle and the detailed standard is to be determined by factors including, but not limited to, the level of integration of building with PV and the technology of PV products. The Interim Measures do not apply to projects completed before March 23, 2009, the promulgation date of the Interim Measures.

On April 16, 2009, the General Offices of the PRC Ministry of Finance and the PRC Ministry of Housing and Urban-Rural Development jointly issued the Guidelines for Declaration of Demonstration Project of Solar Photovoltaic Building Applications. These guidelines set the subsidy given out in 2009 to qualified solar projects at no more than RMB20 per watt for projects involving the integration of PV components into buildings’ structural elements and at no more than RMB15 per watt for projects involving the installation of PV components onto building rooftops and wall surfaces.

On May 27, 2010, the Ministry of Housing and Urban-Rural Development issued the City Illumination Administration Provisions, or the Illumination Provisions, effective as of July 1, 2010. The Illumination Provisions encourage the installation and use of renewable energy systems such as PV systems in the process of construction and re-construction of city illumination projects.

On March 8, 2011, the Notice on Further Promotion of Buildings with Renewable Energy, or the Notice, was jointly released by the PRC Ministry of Finance and the PRC Ministry of Housing and Urban-Rural Development. The Notice expressly specifies the goal of promoting the application of renewable energy in buildings under the Twelfth Five-Year Plan is to substantially improve the proportion of renewable energy used in buildings, including solar energy, shallow geothermal energy and biomass energy, so that the consumption of renewable energy in buildings shall account for over 15% of the total building energy consumption by the end of 2020. The Twelfth Five-Year Plan promotes the use of renewable energy in buildings. The Twelfth Five-Year Plan mandates that efforts shall be made to increase the gross floor areas of buildings serviced by renewable energy to over 2.5 billion square meters and to use renewable energy to substitute 30 million coal by the end of 2015.

Environmental Regulations

We use, generate and discharge toxic, volatile or otherwise hazardous chemicals and wastes in our research and development and manufacturing activities. We are subject to a variety of governmental regulations related to the storage, use and disposal of hazardous materials. The major environmental regulations applicable to us include the Environmental Protection Law of the PRC, the Law of PRC on the Prevention and Control of Water Pollution, Implementation Rules of the Law of PRC on the Prevention and Control of Water Pollution, the Law of PRC on the Prevention and Control of Air Pollution, the Law of PRC on the Prevention and Control of Solid Waste Pollution, and the Law of PRC on the Prevention and Control of Noise Pollution.

Restriction on Foreign Businesses

The principal regulation governing foreign ownership of solar photovoltaic businesses in the PRC is the Foreign Investment Industrial Guidance Catalogue (effective as of December 1, 2007). Under the regulation, the solar photovoltaic business falls into the category of encouraged foreign investment industry.

Tax

PRC enterprise income tax is calculated based on taxable income determined under PRC accounting principles. On March 16, 2007, the National People’s Congress of the PRC passed the EIT, which took effect as of January 1, 2008. In accordance with the EIT, a unified enterprise income tax rate of 25% and unified tax deduction standards are applied equally to both domestic-invested enterprises and foreign-invested enterprises, such as SolarOne Qidong. Enterprises established prior to March 16, 2007 eligible for preferential tax treatment in accordance with the former tax laws and administrative regulations are, under the regulation of the State Council, gradually becoming subject to the new tax rate over a five-year transition period that started on the date of effectiveness of the EIT. In accordance with the Notice of the State Council on the Implementation of the Transitional Preferential Policies in respect of Enterprise Income Tax, foreign-invested enterprises established prior to March 16, 2007 and eligible for preferential tax treatment, such as SolarOne Qidong, will continue to enjoy the preferential tax treatment in the manner and during the period as former laws and regulations provided until such period expires. While the EIT equalizes the tax rates for FIEs and domestically owned enterprises, preferential tax treatment continues to be granted to companies in certain encouraged sectors and to companies classified as “high and new technology enterprises,” which enjoy a tax rate of 15% as compared to the uniform tax rate of 25%. SolarOne Qidong was approved to be qualified as a “high and new technology enterprise” on October 21, 2008. The “high and new technology enterprise” status is valid for a period of three years from the date of issuance of a “high and new technology enterprise” certificate. If there is any significant change in the company’s business operations, manufacturing technologies or other areas that cause it to no longer qualify as a “high and new technology enterprise”, such status will be terminated from the year of such change.

In accordance with the FIE Tax Law, the EIT and other relevant tax regulations, SolarOne Qidong was exempted from state and local enterprise income tax in 2005 and 2006 and was taxed at a reduced rate of 12% in 2007, 12.5% in 2008 and 12.5% in 2009 and 15% in 2010. The “high and new technology enterprise” status of SolarOne Qidong will expire in October 2011. SolarOne Qidong has re-applied for the “high and new technology enterprise” qualification and expects to receive a response from the government regarding the application by August 2011. If SolarOne Qidong’s application is approved, SolarOne Qidong will continue to enjoy a preferential income tax rate of 15% in 2011, 2012 and 2013; and otherwise SolarOne Qidong will be subject to an income tax rate of 25% from 2011. From 2005 until the end of 2009, SolarOne Qidong was also exempt from the 3% local income tax applicable to foreign-invested enterprises in Jiangsu Province. In addition, under relevant PRC tax rules and regulations, SolarOne Qidong was entitled to a two-year income tax exemption on income generated from additional investment in the production capacity of SolarOne Qidong resulting from our contribution to SolarOne Qidong of funds we received through issuances of series A convertible preference shares in a private placement in June and August 2006, and was entitled to a reduced tax rate of 12.5% for the three years thereafter. In 2010, we recorded a provision of RMB116.1 million (US$17.6 million) for unrecognized tax benefits related to SolarOne Qidong due to the uncertainty as to whether this subsidiary would meet certain requirements of “high and new technology enterprise” status during its annual self-assessment in order to be eligible for the reduced EIT. In addition, our subsidiaries, SolarOne Technology and Solar Shanghai, are subject to an enterprise income tax rate of 25% from 2008 onwards.

Pursuant to SAT Circular 698, issued by the State Administration of Taxation on December 10, 2009 with retroactive effect from January 1, 2008, if a non-resident enterprise transfers its equity interests in a PRC resident indirectly via disposing of the equity interests of an overseas holding company, or Indirect Transfer, and such overseas holding company is located in a tax jurisdiction that (i) has an effective tax rate less than 12.5% or (ii) does not tax foreign income of its residents, the foreign investor shall report such Indirect Transfer to the competent tax authority of the PRC resident enterprise. The PRC tax authority will examine the true nature of the Indirect Transfer, and if the tax authority considers that the foreign investor has adopted an abusive arrangement in order to avoid PRC tax, it will disregard the existence of the overseas holding company and re-characterize the Indirect Transfer and, as a result, gains derived from such Indirect Transfer may be subject to PRC withholding tax at the rate of up to 10%. SAT Circular 698 also provides that, where a non-PRC resident enterprise transfers its equity interests in a PRC resident enterprise to its related parties at a price lower than the fair market value, the relevant tax authority has the power to make a reasonable adjustment to the taxable gain of the transaction. SAT Circular 698 states that it does not apply to purchases or sales of stock on a stock exchange.

Pursuant to the Provisional Regulation of China on Value-Added Tax and their implementing rules, all entities and individuals that are engaged in the sale of goods, the provision of repairs and replacement services and the importation of goods in China are generally required to pay value-added tax at a rate of 17% of the gross sales proceeds received, less any deductible value-added tax already paid or borne by the taxpayer. Furthermore, when exporting goods, the exporter is entitled to a portion of or all the refund of value-added tax that it has already paid or borne. Our imported raw materials that are used for manufacturing export products and are deposited in bonded warehouses are exempt from import value-added tax.

Foreign Currency Exchange

Foreign currency exchange in China is primarily governed by the following regulations:

•		Foreign Exchange Administration Rules (1996), as amended; and
•		Regulations of Settlement, Sale and Payment of Foreign Exchange (1996).

Under the Foreign Exchange Administration Rules, the Renminbi is convertible for current account items, including distribution of dividends, payment of interest, trade and service-related foreign exchange transactions. Conversion of Renminbi for capital account items, such as direct investment, loan, securities investment and repatriation of investment, however, is still subject to the approval of SAFE.

Under the Regulations of Settlement, Sale and Payment of Foreign Exchange, foreign-invested enterprises may only buy, sell and/or remit foreign currencies at those banks authorized to conduct foreign exchange business after providing valid commercial documents and, in the case of capital account item transactions, obtaining approval from the SAFE. Capital investments by foreign-invested enterprises outside of China are also subject to limitations, which include approvals by the Ministry of Commerce, SAFE and the NDRC.

Dividend Distribution

The principal regulations governing distribution of dividends paid by wholly foreign-owned enterprises include:

•		Wholly Foreign-Owned Enterprise Law (1986), as amended; and
•		Wholly Foreign-Owned Enterprise Law Implementation Rules (1990), as amended.

Under these regulations, wholly foreign-owned enterprises in China may pay dividends only out of their accumulated profits, if any, determined in accordance with PRC accounting standards and regulations. In addition, wholly foreign-owned enterprises in China are required to set aside at least 10% of their after-tax profit based on PRC accounting standards each year to its general reserves until the accumulated amount of such reserves reaches 50% of its registered capital. These reserves are not distributable as cash dividends. The board of directors of a foreign-invested enterprise has the discretion to allocate a portion of its after-tax profits to staff welfare and bonus funds, which may not be distributed to equity owners except in the event of liquidation.

C. Organizational Structure

Hanwha Solar Holdings Co., Ltd., or Hanwha Solar, became our largest shareholder through a series of transactions in September 2010. Hanwha Solar, a company that engages in solar business, is a wholly-owned subsidiary of Hanwha Chemical Corporation, a leading chemical producer publicly traded on the Korea Exchange whose principal activities are the production of CA, PE, and PVC products. After Hanwha Solar became our largest shareholder, we changed our name from “Solarfun Power Holdings Co., Ltd.” to “Hanwha SolarOne Co., Ltd.” on December 20, 2010 and our ticker from “SOLF” to “HSOL” on February 15, 2011. We also changed the names of our subsidiaries. The diagram below sets forth the entities directly or indirectly controlled by us as of April 30, 2011.

D. Property, Plant and Equipment

Our corporate headquarters and manufacturing facilities are located in the Linyang Industrial Park, Qidong, Jiangsu Province, China, where we hold the land use rights for a total area of 258,319 square meters, which expire between 2053 and 2060. We own office and manufacturing facilities for a total gross floor area of 79,138 square meters in Qidong, Jiangsu Province. We leased an office of 3,600 square meters in Qidong, Jiangsu Province from Linyang Electronics, which will expire on January 8, 2012. To facilitate our capacity expansion, we leased manufacturing facilities with a total gross floor area of approximately 45,500 square meters and dormitories with a total gross floor area of approximately 39,635 square meters in Qidong, Jiangsu Province. The leases will expire between June 2011 and January 2013, when our new facilities are expected to be put into use. In addition, SolarOne Technology holds the land use rights for a total area of approximately 976,905 square meters and owns office and manufacturing facilities for a total gross floor area of 33,730 square meters in Lianyungang, Jiangsu Province. We also renewed the lease of a gross floor area of approximately 1,500 square meters for our Hanwha SolarOne Engineering, Research and Development Center Co., Ltd. in Shanghai in May 2010, and the renewed lease will expire in May 2014. We entered into a contract with Qidong Huahong Electronics Co., Ltd., a company controlled by Mr. Yonghua Lu, our former chairman, to lease an office with a gross floor area of 1,116 square meters from September 1, 2010 to August 31, 2013. In 2008, 2009 and 2010, our rental expenses were RMB6.3 million, RMB9.6 million and RMB9.4 million (US$1.4 million), respectively.

As of April 30, 2010, we had an annual PV module production capacity of 1,000 MW and an annual PV cell production capacity of 700 MW. As of April 30, 2010, we also had 415 MW of annual ingot production capacity and 500 MW of annual wire sawing capacity.

We believe that our existing facilities are adequate and suitable to meet our present needs. We are now constructing buildings in Qidong and Lianyungang to accommodate our planned expansion of production capacity. In December 2010, we entered into an investment letter of intent with Nantong Economic and Technological Development Zone to build cell and module production facilities with an annual production capacity of 2 GW in Nantong, Jiangsu Province.

ITEM 5 OPERATING AND FINANCIAL REVIEW AND PROSPECTS

The following discussion should be read in conjunction with the rest of this annual report, including the consolidated financial statements and notes thereto contained elsewhere in this annual report. The results discussed below are not necessarily indicative of the results to be expected in any future periods.

A. Operating Results

Overview

We are a vertically integrated manufacturer of silicon ingots, silicon wafers, PV cells and PV modules in China. We manufacture a variety of silicon ingots, silicon wafers, PV cells and PV modules using advanced manufacturing process technologies that have helped us to rapidly increase our operational efficiency. Since 2009, substantially all of the ingots, wafers and PV cells we produced have been used for our own PV module production. We also provide PV module processing services. We sell PV cells and PV modules both directly to system integrators and through third-party distributors.

We commenced operations on August 27, 2004 through SolarOne Qidong. On August 27, 2004, Linyang Electronics, one of the leading electricity-measuring instrument manufacturers in China, owned 68% of the equity interests of SolarOne Qidong. In anticipation of our initial public offering, we incorporated Hanwha SolarOne in the Cayman Islands on May 12, 2006 as our listing vehicle. To enable us to raise equity capital from investors outside of China, we established a holding company structure by incorporating SolarOne BVI in the British Virgin Islands on May 17, 2006. SolarOne BVI is wholly owned by Hanwha SolarOne. SolarOne BVI purchased all of the equity interests in SolarOne Qidong on June 2, 2006 from Linyang Electronics and the three other shareholders of SolarOne Qidong for aggregate consideration of US$7.3 million. This transaction was accounted for as a recapitalization. On May 16, 2007, SolarOne BVI established a wholly owned subsidiary, SolarOne Hong Kong. In March 2006, April 2006 and April 2007, we established three majority-owned or wholly owned subsidiaries in China, Solar Shanghai, Sichuan Jiayang and Solar R&D, respectively, to expand our business into new markets and sectors. We acquired a 52% equity interest in Solar Technology in July 2007 and acquired the remaining 48% in August 2008. In September 2007, we established a wholly owned subsidiary, SolarOne U.S.A., as part of our plan to enter the United States market. On November 30, 2007, SolarOne BVI transferred all of the equity interests in SolarOne Qidong to SolarOne Hong Kong for consideration of US$199.0 million. In February 2008, we established a wholly owned subsidiary, SolarOne Deutschland in Germany, to sell solar products in the European markets. We liquidated Sichuan Jiayang, one of our subsidiaries which historically has had limited operations, in July 2008. In November 2009, we acquired the remaining 17% interest in Solar Shanghai and Solar Shanghai became our wholly owned subsidiary after the completion of this transaction. We established Hanwha Solar Electric Power Engineering Co., Ltd. in May 2010 under SolarOne Qidong to engage in the solar power project business.

We entered into a share purchase agreement on August 3, 2010 with Hanwha Chemical Corporation, or Hanwha Chemical, a leading chemical producer publicly traded on the Korea Exchange whose principal activities are the production of CA, PE and PVC products. Under such share purchase agreement, Hanwha Chemical agreed to purchase 36,455,089 ordinary shares from us at a price of US$2.144 per ordinary share, which corresponds to a price of US$10.72 per ADS. Hanwha Chemical subsequently assigned and transferred its rights and obligations under the share purchase agreement to Hanwha Solar, a wholly owned subsidiary of Hanwha Chemical and the sale and purchase of these ordinary shares was consummated on September 16, 2010. In addition, we entered into a share issuance and repurchase agreement on September 16, 2010 with Hanwha Solar, under which we agreed to issue to Hanwha Solar a total of 45,080,019 ordinary shares at par value of US$0.0001 per ordinary share, which shares shall remain outstanding so long as and to the extent that the 9,019,611 ADSs we issued to facilitate our convertible bond offering in January 2008 remain outstanding. Pursuant to the share issuance and repurchase agreement, we issued to Hanwha Solar 30,672,689 ordinary shares on September 16, 2010 and an additional 14,407,330 ordinary shares on March 10, 2011. The total proceeds to us from these transactions amounted to US$78.2 million. At the same time, Hanwha Solar completed the acquisitions from Good Energies II LP and Yonghua Solar Power Investment Holding Ltd. of a total of 120,407,700 ordinary shares and 1,281,011 ADSs of our company, representing all of the ordinary shares and ADSs held by them. In connection with our public offering of 9,200,000 ADSs in November 2010, we issued to Hanwha Solar an additional 45,981,604 ordinary shares at a price of US$1.80 per ordinary share pursuant to a shareholder agreement we and Hanwha Solar entered into on September 16, 2010. As a result of these transactions, Hanwha Solar owns an approximately 49.8% equity interest in our company. We changed our name from “Solarfun Power Holdings Co., Ltd.” to “Hanwha SolarOne Co., Ltd.” on December 20, 2010 and our ticker from “SOLF” to “HSOL” on February 15, 2011. In April 2011, we established Nantong Hanwha Import & Export Co., Ltd., or Nantong Hanwha I&E, under SolarOne Qidong to engage in import and export of PV products and technology and Hanwha SolarOne (Nantong) Co., Ltd., or SolarOne Nantong, under SolarOne Hong Kong to develop, manufacture and sell PV products.

We shipped 172.8 MW, 313.4 MW and 797.9 MW of PV modules (including PV module processing) in 2008, 2009 and 2010, respectively. The average selling price of our PV modules (excluding PV module processing) was RMB26.77, RMB15.27 and RMB11.58 (US$1.75) per watt in 2008, 2009 and 2010, respectively. In 2008, 2009 and 2010, 93.3%, 95.3% and 92.1%, respectively, of our net revenues were attributable to sales to customers outside of the PRC. Moreover, in 2008, 2009 and 2010, customers accounting for more than 10% of our net revenues accounted in the aggregate for 22.2%, 41.4% and 33.6%, respectively, of our net revenues.

Our net revenues decreased from RMB4,949.1 million in 2008 to RMB3,778.3 million in 2009, but increased to RMB7,527.0 million (US$1,140.5 million) in 2010. Our consolidated net income increased from a net loss of RMB265.9 million in 2008 to a net loss of RMB144.9 million in 2009, and increased to net income of RMB757.4 million (US$114.8 million) in 2010.

Limited Operating History

We have a limited operating history upon which you can evaluate our business. You should consider the risks and difficulties frequently encountered by companies with a relatively short operating history, such as us, in new and rapidly evolving markets, such as the PV market. Our rapid revenue growth since we started operations in August 2004 should not be taken as indicative of the rate of revenue growth, if any, that can be expected in the future. In addition, our limited operating history provides a limited historical basis to assess the impact that critical accounting policies may have on our business and our financial performance.

Key Factors Affecting Our Financial Performance

The most significant factors affecting our financial performance are:

•		industry demand;
•		average selling price of our PV products;
•		price and availability of silicon and silicon wafers;
•		manufacturing capacity; and
•		process technologies.

Industry Demand

Our business and revenue growth depends on PV industry demand. There has been significant growth in the PV market in the past decade. However, beginning in the second half of 2008, many of our key markets, including Germany, Spain and the United States, and other national economies have experienced a period of economic contraction or significantly slower economic growth. In particular, the current credit crisis, weak consumer confidence and diminished consumer and business spending have contributed to a significant slowdown in the market demand for PV products due to decreased energy requirements. Many of our customers have experienced difficulty in obtaining financing, and even if they have been able to obtain financing, the cost of such financing has increased and our customers may change their decision or change the timing of their decision to purchase our products. As a result, this lack of, and increase in the cost of, financing have lowered and may continue to lower demand for our products and reduced our net revenues. A protracted disruption in the ability of our customers to obtain financing could lead to a significant reduction in their future orders for our products, which in turn could have a material adverse effect on our business, financial condition and results of operations. See “Item 3.D. Risk Factors—Risks related to Our Company and Our Industry—Demand for our PV products has been, and may continue to be, adversely affected by volatile market and industry trend.” From the second half of 2008 to the first half of 2009, increased manufacturing capacity in the industry also contributed to a decline in the selling price of PV products. As global economic condition began improving in the second half of 2009, demand for PV products began to increase during 2010, which contributed to an increase in the selling price of PV products in 2010 along with the decreased manufacturing capacity in 2010. Such increase was offset by the sale of inventory accumulated during the economic downturn. A large portion of our sales is denominated in Euros. The depreciation of Euro in the first half of 2010 and the appreciation of Euro in the second half of 2010 also contributed to the change of our average selling price per watt of our PV modules in 2010.

The average selling price per watt of our PV modules decreased from RMB26.77 in 2008 to RMB15.27 in 2009 and RMB11.58 (US$1.75) in 2010. The average selling price per watt of our PV modules decreased from RMB13.3 in the last quarter of 2009 to RMB12.01 in the first quarter of 2010 and RMB11.19 in the second quarter of 2010 and rebounded to RMB11.72 and RMB11.82, respectively, in the third and fourth quarter of 2010. The change in the average selling price per watt of our PV modules is consistent with the industry trend.

Average Selling Price of Our PV Products

PV products are priced based on the number of watts of electricity they can generate. Pricing of PV products is principally affected by manufacturing costs, including the costs of silicon and silicon wafers, as well as the overall demand in the PV industry. Increased economies of scale and advancement of process technologies over the past decade have also led to a reduction in manufacturing costs and the prices of PV products.

We generally price our products based on the prevailing market price at the time our customers issue purchase orders, taking into account the size of the purchase order, the strength and history of our relationship with each customer and our capacity utilization. Beginning in the fourth quarter of 2008, demand for PV products decreased as a result of the global financial crisis, but the supply of PV products increased significantly as many manufacturers of PV products worldwide, including our company, engaged in significant production capacity expansion in recent years. This state of over-supply has resulted in reductions in the prevailing market prices of PV products as manufacturers have reduced their average selling prices in an attempt to obtain sales. The average selling prices of our products started to decline in the fourth quarter of 2008. The average selling price per watt of our PV modules (excluding PV module processing) decreased from RMB26.77 in 2008 to RMB15.27 in 2009, and to RMB11.58 (US$1.75) in 2010. The changes in the average selling prices of our PV modules primarily reflected the prevailing market trend. We expect that the prices of PV products will continue to decline over time due to increased supply of PV products, reduced manufacturing costs from improving technology and economies of scale, and continuing decreases in the prices of silicon and silicon wafers.

Price and Availability of Silicon and Silicon Wafers

Prior to mid-2008, there was an industry-wide shortage of silicon and silicon wafers, which resulted in significant price increases. To secure an adequate and timely supply of silicon and silicon wafers during the earlier periods of supply shortage, we entered into a number of multi-year supply agreements. The prices in the agreements we entered into prior to mid-2008 were generally pre-determined, but some of these agreements provided for adjustments in subsequent years to reflect changes in market conditions or through mutual agreement.

Since the fourth quarter of 2008, the market prices for silicon and silicon wafers have been decreasing significantly. Spot market prices of silicon and silicon wafer prices have fallen below the price we have contracted for with our long-term suppliers and continued to decline in 2009. The rapid declines in the prices of silicon and silicon wafers coupled with decreases in demand for PV products have hampered our ability to pass on to our customers the cost of our raw materials which were procured at higher prices during the earlier period of supply shortage. As a result, our write-down of inventories amounted to RMB413.8 million, RMB282.6 million and RMB134.5 million (US$20.5 million) in 2008, 2009 and 2010, respectively.

Due to the significant decrease in prices of silicon and silicon wafers, we re-negotiated all of our multi-year supply agreements that were in place as of December 31, 2009, except the agreement with LDK. After re-negotiation, the terms of price of such multi-year agreements were generally subject to review either periodically or upon significant changes in prices on the spot market. Currently, there is only one multi-year supply agreement we entered into in 2010 where the price is pre-determined without any future adjustment. In 2010, the amount of our write-down of inventories attributable to the difference between spot market prices and the prices we have contracted for are not material. Silicon and silicon wafers secured through such multi-year supply agreements provided a significant portion of our silicon and silicon wafer needs in 2009 and 2010, and we expect these contracts will provide a significant portion of our anticipated silicon and silicon wafer needs for 2011. If we are unable to re-negotiate the prices of our existing multi-year supply agreements and the prices of silicon and silicon wafers continue to decrease in the future, we may not be able to adjust our materials costs, and our cost of revenues would be materially and adversely affected.

We have historically also acquired a portion of our polysilicon and silicon wafers through short-term supply arrangements for periods ranging from several months to one year and spot market purchases. The prices we pay for silicon and silicon wafers pursuant to short-term supply arrangements and spot market purchases vary according to the prevailing market price around the time of delivery, which can be subject to significant fluctuations. All of our short-term supply arrangements have expired pursuant to their terms, and due to our expectations of market conditions, we anticipate fulfilling any needs for silicon and silicon wafers in excess of the volumes to be delivered under our multi-year supply agreements through purchases on the spot market, rather than through new short-term supply arrangements.

Manufacturing Capacity

Capacity and capacity utilization are key factors in growing our net revenues and gross profit. In order to accommodate the growing demand for our products, we have significantly expanded our manufacturing capacity in recent years. An increase in capacity has a significant effect on our financial results, both by allowing us to produce and sell more PV products and achieve higher net revenues, and by lowering our manufacturing costs as a result of increased economies of scale.

We have been seeking to maximize the utilization of our available manufacturing capacity as it comes on-line, so as to allow us to spread our fixed costs over a higher production volume, thereby reducing our per unit and per MW fixed costs. As we build additional production facilities, our fixed costs will increase, and the overall utilization rate of our production facility could decline, which could negatively impact our gross profit. However, regardless of the capacity of a particular manufacturing facility, our capacity utilization may vary greatly depending on the mix of products we produce at any particular time.

We have expanded rapidly our manufacturing capacity since our establishment in August 2004. As a result, we produced 177.3 MW, 342.8 MW and 797.9 MW of PV modules in 2008, 2009 and 2010, respectively. The following table sets forth the production volume of silicon ingots, wafer PV cells and PV modules for the periods indicated:

		Year Ended December 31,
		2006				2007				2008				2009				2010
		(MW)				(MW)				(MW)				(MW)				(MW)
Volume of ingots produced			—				—				48.0				154.1				360.0
Volume of wafer produced			—				—				23.5				164.6				387.4
Volume of PV cells produced (including PV cell processing)			26.2	(1)			99.6	(2)			191.5	(3)			260.2	(4)			502.4	(5)
Volume of PV modules produced (including PV module processing)			19.6				87.2				177.3				342.8				758.9

As of April 30, 2011, we had an annual PV module production capacity of 1,000 MW and an annual PV cell production capacity of 700 MW. As of April 30, 2011, we also had 415 MW of annual ingot production capacity and 500 MW of annual wire sawing capacity.

Process Technologies

Advancements of process technologies have enhanced conversion efficiencies of PV products. Assuming other things being the same, high conversion efficiencies reduce the manufacturing cost per watt of PV products and could thereby contribute to increasing gross profit margins. For this reason, solar energy companies, including us, are continuously developing advanced process technologies for large-scale manufacturing while reducing costs to maintain and improve profit margins.

We have achieved improvements in process technology and product quality since we commenced our commercial production in November 2005. Our monocrystalline and multicrystalline PV cells achieved conversion efficiency rates in the ranges of 17.3% to 18.3% and 15.5% to 17.0%, respectively, in 2010 and we are now able to process wafers as thin as 180 microns. Our advanced process technologies have also significantly improved our productivity and increased the efficiency of our raw material usage, both of which have led to the lowering of the cost per watt of our products and improved our gross profit margins.

Net Revenues

We currently generate a substantial majority of our net revenues from the production and sale of PV modules. We also generate a small portion of our net revenues from the sale of PV cells and raw materials to third parties.

We commenced manufacturing and selling PV modules in February 2005, and had net revenues of RMB4,626.4 million, RMB3,375.6 million and RMB6,658.6 million (US$1,008.9 million) in 2008, 2009 and 2010, respectively.

We began manufacturing PV cells in November 2005, primarily to supply our PV module production. As a result, we only sold a small number of the total PV cells we manufactured to certain customers to maintain business relationships. Since our business strategy is focused on increasing our own output of PV modules on a cost-efficient basis, we plan to continue to use the substantial majority of our PV cells in manufacturing our PV modules and will maintain our sale of PV cells to third parties at a relatively low level. In 2008, 2009 and 2010, our net revenues from the sale of PV cells were RMB253.1 million, RMB38.4 million and RMB100.6 million (US$15.2million), respectively.

We began to provide PV module processing services to produce PV modules from PV cells provided by our customers in 2007. We recorded the amount of net revenues on PV module processing transactions based on the amount received from a customer for PV modules sold less the amount paid for PV cells purchased from the same customer.

In the event we pay the shipping costs on behalf of our customers, we include the shipping costs passed on to our customers in our net revenues.

In 2008, 2009 and 2010, a portion of our net revenues was derived from the sale of raw materials to our customers.

We record revenue net of all value-added taxes imposed by governmental authorities and collected by us from customers concurrent with revenue-producing transactions.

We currently depend on a limited number of customers for a high percentage of our net revenues. Customers who individually accounted for more than 10% of our net revenues accounted for an aggregate of 22.2%, 41.4% and 33.6% of our net revenues in 2008, 2009 and 2010, respectively. From a geographic standpoint, Europe, particularly Germany, has been our largest market. Based on the location that our invoices are sent to, in 2008, 2009 and 2010, our sales to European customers accounted for 92.5%, 85.8% and 79.6%, respectively, of our net revenues, with German customers accounting for 53.3%, 70.6% and 62.5%, respectively, in such periods. Although we anticipate that our dependence on a limited number of customers in a few concentrated geographic regions will continue for the foreseeable future, we are actively expanding our customer base and geographic coverage through various marketing efforts, especially in other developing PV markets, such as the United States, Spain, Italy, Australia and China.

Sales to our customers are typically made through non-exclusive, short-term arrangements. Before the beginning of 2009, we generally required deposits of a certain percentage of the contract price from our customers which we recorded under customer deposits in our consolidated balance sheets. Once the revenue recognition criteria are met, we then recognize these payments as net revenues. In line with market trends, this practice of requiring our customers to make deposits is on the decline. Deposits we received increased from 2008 to 2009 despite the current market trends, primarily because we required deposits from certain of our customers based on their credit quality. As of December 31, 2008, 2009 and 2010, we had received deposits of RMB9.5 million, RMB59.7 million and RMB33.5 million (US$5.1 million), respectively.

Cost of Revenues and Operating Expenses

Cost of Revenues

The following table sets forth our cost of revenues and operating expenses and these amounts as percentages of our net revenues for the periods indicated.

Our cost of revenues includes the cost of raw materials used for our PV module and PV cell production and PV module processing, such as silicon and silicon wafers, and other direct raw materials and components, including ethylene vinyl acetate, triphenyltin, tempered glass, connecting bands, welding bands, silica gel, aluminum alloy and junction boxes. The costs relating to providing the PV module processing services were recorded within cost of revenues. We expect the cost of silicon and silicon wafers, our primary raw material for the manufacturing of PV products, will continue to constitute a substantial portion of our cost of revenues in the near future.

Other items contributing to our cost of revenues are direct labor, which includes salaries and benefits for personnel directly involved in manufacturing activities, manufacturing overhead, which consists of utility, maintenance of production equipment, shipping and handling costs for products sold, and other support expenses associated with the manufacturing of our PV products, and depreciation and amortization of manufacturing equipment and facilities.

We expect our cost of revenues to increase as we increase our production volume. Future increases in our suppliers’ cost of silicon wafers as well as the potential increase in shipping costs for our PV products may also contribute to higher cost of revenues.

Silicon and silicon wafers are the most important raw materials for our products. We record the purchase price of silicon and silicon wafers and other raw materials initially as inventory in our consolidated balance sheets, and then transfer this amount to our cost of revenues after the raw materials are consumed in our manufacturing process and the finished products are sold and delivered. As of December 31, 2008, 2009 and 2010, our inventory of raw materials totaled RMB488.6 million, RMB277.6 million and RMB459.5 million (US$69.6 million), respectively, of which RMB353.3 million, RMB146.8 million and RMB286.3 million (US$43.4 million), respectively, represented silicon and silicon wafers. Silicon suppliers generally require prepayments from us in advance of delivery. We classify such prepayments as advances to suppliers and record such prepayments under either non-current assets or current assets in our consolidated balance sheets. However, if such suppliers fail to fulfill their delivery obligations under the silicon supply agreements or if there is any dispute between us and such suppliers that jeopardizes our ongoing relationship, we may not be able to recover such prepayments and would suffer losses.

Operating Expenses

Our operating expenses consist of selling expenses, general and administrative expenses and research and development expenses.

Selling Expenses

Our selling expenses primarily consist of warranty costs, advertising and other promotional expenses, and salaries, commissions, traveling expenses and benefits for our sales and marketing personnel. In 2008, 2009 and 2010, our selling expenses were RMB87.9 million, RMB105.5 million and RMB178.1 million (US$27.0 million), respectively. As we intend to pursue an aggressive marketing strategy to promote our products in different geographic markets, we expect that our selling expenses will increase for the immediate future.

We provide a two to five-year warranty for technical defects and a 10-year limited warranty against declines of greater than 10%, and a 20 to 25-year limited warranty against declines of greater than 20%, in the initial power generation capacity of our PV modules. We consider various factors when determining the likelihood of product defects, including an evaluation of our quality controls, technical analysis, industry information on comparable companies and our own experience. As of December 31, 2008, 2009 and 2010, our accrued warranty costs for the two to five-year warranty against technical defects totaled RMB48.6 million, RMB73.5 million and RMB131.7 million (US$20.0 million), respectively. Since our products have been in use for only a relatively short period, our assumptions regarding the durability and reliability of our products may not be accurate. In 2008, 2009 and 2010, we provided RMB46.6 million, RMB33.7 million and RMB67.6 million (US$10.2 million), respectively, in warranty costs.

General and Administrative Expenses

Our general and administrative expenses primarily consist of salaries and benefits of our administrative staff, depreciation charges of fixed assets used for administrative purposes, as well as administrative office expenses including consumables, traveling expenses, insurance and share compensation expenses. In 2008, 2009 and 2010, our general and administrative expenses were RMB143.3 million, RMB181.0 million and RMB190.6 million (US$28.9 million), respectively.

Research and Development Expenses

Our research and development expenses primarily consist of salaries and benefits of our research and development staff, other expenses including depreciation, materials used for research and development purposes, and the travel expenses incurred by our research and development staff or otherwise in connection with our research and development activities. We expense our research and development costs as incurred. In 2008, 2009 and 2010, our research and development expenses were RMB19.7 million, RMB32.0 million and RMB53.5 million (US$8.1 million), respectively. We believe that research and development is critical to our strategic objectives of enhancing our technologies, reducing manufacturing costs and meeting the changing requirements of our customers. As a result, we expect that our total research and development expenses will be similar or will increase in the future.

Share-based Compensation Charges

We adopted our 2006 share option plan in November 2006 pursuant to which we may issue up to 10,799,685 ordinary shares upon exercise of awards granted under the plan. As of December 31, 2010, options to purchase 4,910,650 ordinary shares have been granted and were outstanding under this plan.

We adopted our 2007 equity incentive plan in August 2007 which provides for the grant of options, restricted stock, restricted stock units, stock appreciation rights, performance units and performance stock to our employees, directors and consultants. The maximum aggregate number of our ordinary shares that may be issued under the 2007 equity incentive plan is 10,799,685. In addition, the plan provides for an annual increase in the number of shares available for issuance on the first day of each fiscal year, beginning with our 2008 fiscal year, equal to 2% of our then outstanding ordinary shares or such lesser amount as our board of directors may determine. As of December 31, 2010, options to purchase 10,724,910 ordinary shares have been granted and were outstanding under this plan.

In 2008, 2009 and 2010, we recorded RMB34.8 million, RMB42.7 million and RMB32.0 million (US$4.8 million), respectively, as share-based compensation charges.

Taxation

PRC Enterprise Income Tax

PRC enterprise income tax is calculated based on taxable income determined under PRC accounting principles. On March 16, 2007, the National People’s Congress of the PRC passed the EIT, which took effect as of January 1, 2008. On December 6, 2007, the State Council of the PRC issued Implementation Regulations regarding the EIT which took effect as of January 1, 2008. In accordance with the EIT and its Implementation Regulations, a unified enterprise income tax rate of 25% and unified tax deduction standards are applied equally to both domestic-invested enterprises and foreign-invested enterprises such as SolarOne Qidong. Enterprises established prior to March 16, 2007 and eligible for preferential tax treatment in accordance with the former tax laws and administrative regulations shall, under the regulations of the State Council, gradually are becoming subject to the new tax rate over a five-year transition period starting from the date of effectiveness of the EIT. In accordance with the Notice of the State Council on the Implementation of the Transitional Preferential Policies in respect of Enterprise Income Tax, foreign-invested enterprises established prior to March 16, 2007 and eligible for preferential tax treatment, such as SolarOne Qidong, will continue to enjoy the preferential tax treatment in the manner and during the period as former laws and administrative regulations provided until such period expires. While the EIT equalizes the tax rates for FIEs and domestically owned enterprises, preferential tax treatment continues to be granted to companies in certain encouraged sectors and to companies classified as “high and new technology enterprises,” which enjoy a tax rate of 15% as compared to the uniform tax rate of 25%. SolarOne Qidong was approved to be qualified as a “high and new technology enterprise” on October 21, 2008. The “high and new technology enterprise” status is valid for a period of three years from the date of issuance of a “high and new technology enterprise” certificate. If there is any significant change in the company’s business operations, manufacturing technologies or other areas that cause it to no longer qualify as a “high and new technology enterprise”, such status will be terminated from the year of such change.

In accordance with the FIE Tax Law, the EIT and other relevant tax regulations, SolarOne Qidong was exempted from state and local enterprise income tax in 2005 and 2006 and was taxed at a reduced rate of 12% in 2007, 12.5% in 2008, 12.5% in 2009, and 15% in 2010. The “high and new technology enterprise” status of SolarOne Qidong will expire in October 2011. SolarOne Qidong has re-applied for the “high and new technology enterprise” qualification and expects to receive a response from the government regarding the application by August 2011. If SolarOne Qidong’s application is approved, SolarOne Qidong will continue to enjoy a preferential income tax rate of 15% in 2011, 2012 and 2013; otherwise SolarOne Qidong will be subject to an income tax rate of 25% from 2011. In 2010, we recorded a provision of RMB116.1 million (US$17.6 million) for unrecognized tax benefits related to SolarOne Qidong due to the uncertainty as to whether this subsidiary would meet certain requirements of “high and new technology enterprise” status during its annual self-assessment in order to be eligible for the reduced EIT rate of 15%. From 2005 until the end of 2009, SolarOne Qidong was also exempt from the 3% local income tax applicable to foreign-invested enterprises in Jiangsu Province. In addition, under relevant PRC tax rules and regulations, SolarOne Qidong was entitled to a two-year income tax exemption on income generated from additional investment in the production capacity of SolarOne Qidong resulting from our contribution to SolarOne Qidong of funds we received through issuances of series A convertible preference shares in a private placement in June and August 2006, and is entitled to a reduced tax rate of 12.5% for the three years thereafter. If SolarOne Qidong no longer qualifies for the preferential enterprise income tax rate, we will consider available options under applicable law that would enable us to qualify for alternative preferential tax treatment. To the extent we are unable to offset the expiration of this preferential tax treatment with other tax benefits, the expiration of this preferential tax treatment will cause our effective tax rate to increase. Our subsidiaries, SolarOne Technology and Solar Shanghai, are subject to an enterprise income tax rate of 25% from 2008 onwards.

Critical Accounting Policies and Estimates

We prepare our consolidated financial statements in conformity with U.S. GAAP, which requires us to make estimates and assumptions that affect the reported amounts of, among other things, assets, liabilities, revenue and expenses. We base our estimates on our own historical experience and on various other factors that we believe to be relevant under the circumstances. Actual results may differ from these estimates under different assumptions or conditions. Some of our accounting policies require higher degrees of judgment than others in their application. We consider the policies discussed below to be critical to an understanding of our financial statements as their application places the most significant demands on our management’s judgment.

Revenue Recognition

Our primary business activity is to produce and sell PV modules. We periodically, upon special request from customers, sell PV cells and silicon ingots. We record revenue related to the sale of PV modules, PV cells and silicon ingots when the criteria of Accounting Standards Codification, or ASC, 605-10, “Revenue Recognition: Overall” are met. These criteria include all of the following: persuasive evidence of an arrangement exists; delivery has occurred; the sales price is fixed or determinable; and collectibility is reasonably assured.

More specifically, our sales arrangements are evidenced by either framework sales agreements and/or by individual sales agreements for each transaction. The shipping terms of our sales arrangements are generally “Cost, Insurance and Freight,” or CIF, and “Free on Board,” or FOB, shipping point whereby the customer takes title and assumes the risks and rewards of ownership of the products upon delivery to the shipper. The customer bears all costs and risks of loss or damage to the goods from that point. Under some sales arrangements, we require our customers to prepay prior to shipment. We perform on-going credit assessment of each customer, including reviewing the customer’s latest financial information and historical payment record and performing necessary due diligence to determine acceptable credit terms. In instances where we granted longer credit terms to certain customers, the timing of revenue recognition has not been impacted as we have historically been able to collect under the original payment terms without making concessions. Other than warranty obligations, we do not have any commitments or obligations to deliver additional products or services to the customers. Based on the above, we record revenue related to product sales upon delivery of the product to the shipper, provided that all other revenue recognition criteria are met at that time.

We periodically enter into processing service arrangements to process PV cells into PV modules. For these service arrangements, we “purchase” PV cells from a customer and contemporaneously agree to “sell” a specified quantity of PV modules back to the same customer. The quantity of PV modules sold back to the customers under these processing arrangements is consistent with the amount of PV cells purchased from the customer based on current production conversion rates. In accordance with ASC 845-15, “Accounting for Purchases and Sales of Inventory with the Same Counterparty”, we record the amount of revenue on these processing transactions based on the amount received for PV modules sold less the amount paid for the PV cells purchased from the customer. These sales are subject to all of the above-noted criteria relating to revenue recognition.

Revenue is recognized net of all value-added taxes imposed by governmental authorities and collected from customers concurrent with revenue-producing transactions. We do not offer implicit or explicit rights of return, regardless of whether goods were shipped to distributors or shipped directly to the end-users, other than due to product defects.

We recognize revenue related to solar systems integration services using the percentage-of-completion method. We estimate our revenues by using the cost-to-cost method, whereby we derive a ratio by comparing the costs incurred to date to the total costs expected to be incurred on the project. We apply the ratio computed in the cost-to-cost analysis to the contract price to determine the estimated revenues earned in each period. A contract may be regarded as substantially completed if the remaining costs are not significant in amount. When we determine that total estimated costs will exceed total revenues under a contract, we record a loss accordingly.

Fixed Assets, Net

Fixed assets are stated at cost net of accumulated depreciation and are depreciated using the straight-line method over the estimated useful lives of the assets, as follows:

Buildings		20 years
Plant and machinery		10 years
Furniture, fixtures and office equipment		5 years
Computer software		5 years
Motor vehicles		5 years
Leasehold improvements		Over the shorter of the lease term or their estimated useful lives

Repair and maintenance costs are charged to expenses when incurred, whereas the cost of renewals and betterment that extend the useful life of fixed assets are capitalized as additions to the related assets. Retirement, sale and disposals of assets are recorded by removing the cost and accumulated depreciation with any resulting gain or loss reflected in the consolidated statements of operations.

Costs incurred in constructing new facilities, including progress payments, interest and other costs relating to the construction are capitalized and transferred to fixed assets upon completion and depreciation commences when the asset is available for its intended use.

Interest costs are capitalized if they are incurred during the acquisition, construction or production of a qualifying asset and such costs could have been avoided if expenditures for the assets have not been made. Capitalization of interest costs commences when the activities to prepare the asset are in progress and expenditures and borrowing costs are being incurred. Interest costs are capitalized until the assets are ready for their intended use. Interest capitalized during the years ended December 31, 2008, 2009 and 2010 amounted to RMB22.5 million, RMB4.3 million and RMB5.4 million (US$0.8 million), respectively.

Warranty Costs

We primarily provide standard warranty coverage on our PV modules sold to customers. The standard warranty provides for a 2 to 5-year warranty against technical defects, a 10-year warranty against a decline from initial power generation capacity of more than 10% and a 20 to 25-year warranty against a decline from initial power generation capacity of more than 20%. Our estimate of the amount of warranty obligation is primarily based on the following considerations: 1) the results of technical analyses, including simulation tests performed on our products by an industry-recognized external certification body as well as internally developed damp heat testing procedures conducted by our engineering team, 2) our historical warranty claims experience, 3) the warranty accrual practices of other companies in the industry that produce PV products that are comparable in engineering design, raw material input and functionality to our products, and which sell products to a similar class of customers, and 4) our expected failure rate and future costs to service failed products. The results of the technical analyses support the future operational efficiency of our PV modules at levels significantly above the minimum guaranteed levels over the respective warranty periods. Our estimate of warranty costs will be affected by the estimated and actual product failure rates, the costs to repair or replace failed products and potential service and delivery costs incurred in correcting a product failure. Based on the above considerations and management’s ability and intention to provide repairs, replacements or refunds for defective products, we accrue for warranty costs for the 2 to 5-year warranty against technical defects based on 1% of net revenues for PV modules. No warranty cost accrual has been recorded for the 10-year and 20 to 25-year warranties because we determined the likelihood of claims arising from these warranties to be remote based on internal and external testing of our PV modules and strong quality control procedures in our production process. If our PV modules fail to perform to the standards of the performance guarantee, we could incur substantial expenses and substantial cash outlays to repair, replace or provide refunds for the under-performing products, which could negatively impact our overall cash position. The basis for the warranty accrual will be reviewed periodically based on actual experience. We do not sell extended warranty coverage that is separately priced or optional.

Impairment of Long-Lived Assets

We evaluate our long-lived assets or asset groups, including intangible assets with finite lives, for impairment whenever events or changes in circumstances (such as a significant adverse change to market conditions that will impact the future use of the assets) indicate that the carrying amount of a group of long-lived assets may not be recoverable. When these events occur, we evaluate for impairment by comparing the carrying amount of the assets to the future undiscounted net cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flows is less than the carrying amount of the assets, we would recognize an impairment loss based on the excess of the carrying amount of the asset group over its fair value.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of the assets acquired and the liabilities assumed of the acquired business. Goodwill is reviewed at least annually for impairment, or earlier if there is an indication of impairment, in accordance with ASC 350, “Goodwill and Other Intangible Assets”. We assign and assess goodwill for impairment at the reporting unit level. As of December 31, 2010, goodwill relates to our acquisition of SolarOne Technology in July 2007 and August 2008.

The performance of the impairment test involves a two-step process. The first step of the impairment test involves comparing the fair value of the reporting unit with its carrying amount, including goodwill. Fair value is primarily determined by computing the future discounted cash flows expected to be generated by the reporting unit. If the reporting unit’s carrying value exceeds its fair value, goodwill may be impaired. If this occurs, we perform the second step of the goodwill impairment test to determine the amount of impairment loss. The fair value of the reporting unit is allocated to its assets and liabilities in a manner similar to a purchase price allocation in order to determine the implied fair value of the reporting unit’s goodwill. If the implied goodwill fair value is less than its carrying value, the difference is recognize an impairment loss.

We performed a goodwill impairment test as of December 31, 2010 and no impairment loss was recognized.

Financial Instruments — Currency Derivative Contracts and Commodity Contracts

Our derivative instruments are principally used to manage currency exchange rate risk and the stability of the purchase price for silver, one of the raw materials used in the production of PV products, and are not used for speculative or trading purposes. Accounting for derivative instruments requires significant estimates and judgments relating to measuring the fair values of the derivative instruments. As of December 31, 2010, we had outstanding cross-currency exchange rate contracts with notional amounts of Euro125.0 million and US$190.0 million and commodity contracts for 102,000 ounces of silver. We record these derivative instruments as current assets or current liabilities, measured at fair value. We estimate the fair value of these foreign currency derivative instruments and commodity contracts using a pricing model based on market observable inputs, which include mark-to-market forward rates at each balance sheet date, spot foreign exchange rates at each balance sheet date, and strike foreign exchange rates and maturity terms of our foreign currency derivative instruments.

Share-based Compensation

We account for the share options granted under our 2006 share option plan and our 2007 equity incentive plan in accordance with ASC 718-10, “Share-Based Compensation” and ASC 505-50, “Accounting for Equity Instruments that Are Entered to Offer the Employees for Acquiring, or in conjunction with Selling Goods or Services,” respectively. In accordance with ASC 718-10, all grants of share options are recognized in the financial statements based on their grant-date fair values. We have elected to recognize compensation expense using the straight-line method for all share options granted with services conditions that have a graded vesting schedule.

With the assistance of an independent third-party valuer, we have applied the Black-Scholes option valuation model in determining the fair value of the options granted before January 1, 2008. We estimate expected volatility at the date of grant based on a combination of historical and implied volatilities from comparable publicly listed companies. Forfeiture rate is estimated based on historical forfeiture patterns and adjusted to reflect future change in facts and circumstances, if any.

For share options and restricted stock units granted after January 1, 2008, the fair value of each grant is estimated on the date of grant using a binomial-lattice model. Similar to the Black-Scholes model, the binomial-lattice option model takes into account variables such as expected volatility, dividend yield, and risk-free interest rates. Risk-free interest rates are based on zero coupon U.S. risk-free rates for the terms consistent with the expected life of the award at the time of grant. Expected life is computed based on our estimation of exercise patterns which we believe are representative of future behavior. Expected dividend yield is determined based on our historical dividend payout rate. Expected volatility is estimated based on a combination of our historical performance and the performance of comparable publicly listed companies.

In addition, the binomial-lattice model considers the contractual term of the option, the probability that the option will be exercised prior to the end of its contractual life, and the probability of termination or retirement of the option holder in computing the value of the option.

Accounting for Income Taxes and Uncertain Income Tax Positions

We account for income taxes in accordance with ASC 740, “Accounting for Income Taxes.” Under this method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and tax bases of assets and liabilities using enacted tax rates that will be in effect in the period in which the differences are expected to reverse. We record a valuation allowance to offset deferred tax assets if, based on the weight of available evidence, it is more likely than not that some portion, or all, of the deferred tax assets will not be realized. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date.

We also apply ASC 740-10, “Accounting for Uncertainty in Income Taxes”, which prescribes the recognition threshold a tax position is required to meet before being recognized in the financial statements. As of December 31, 2009 and 2010, we recorded unrecognized tax benefits of RMB27.4 million and RMB143.5 million (US$21.7 million), respectively.

We have elected to classify interest and/or penalties related to an uncertain position, if and when required, as part of “other operating expenses” in the consolidated statements of operations. No such amounts have been incurred or accrued through December 31, 2010.

Based on existing PRC tax regulations, the tax years of SolarOne Qidong, Solar Shanghai, SolarOne Technology, Solar R&D, and Solar Engineering for the years ended December 31, 2006 through 2010 remain open for examination by the tax authorities.

Advance to Suppliers and Long-term Prepayments

Advance to suppliers and long-term prepayments represent interest-free cash deposits paid to suppliers for future purchases of raw materials. According to the multi-year framework supply agreements entered into between us with our suppliers, we were required to provide deposits to our suppliers in order to secure supply of silicon due to limited availability. The multi-year framework supply agreements entered into between us and our suppliers indicated minimum quantities with associated pricing set for the annual periods under the agreements with deliveries to be made over a general timeframe, subject to change based on our purchasing needs and/or the suppliers’ product availability.

As a result of a steep decline in the spot price for silicon products, during 2009, we successfully completed re-negotiating all of our multi-year framework supply agreements that were in place as of December 31, 2009, except the agreement with LDK, through either supplemental agreements or amended and restated multi-year framework supply agreements. Each of these subsequent agreements contains provisions which allow for reassessment of the purchase price for future deliveries under the agreements; however, the subsequent agreements generally did not adjust the originally contracted purchase quantities. As such, the multi-year framework supply agreements, original and as amended, effectively represent commitments to purchase minimum quantities. Our suppliers have been willing to adjust the pricing terms of the original framework supply agreement in order to maintain long-term business relations with us. Such renegotiations have been common practice in the industry given the volatility in the silicon market beginning in late 2008, which resulted in pricing that was vastly different from the levels anticipated when the framework agreements were initially entered into. In addition, as such price adjustments have been reflective of the then-current market conditions, the suppliers can continue to receive fair compensation while avoiding the risks associated with seeking new customers and potential adverse consequences to reputation in the midst of a highly competitive and volatile market.

The supplemental agreements or amended and restated multi-year framework supply agreements have also removed a clause which was previously included in the original multi-year framework supply agreements that provide us with the right to terminate the multi-year framework supply agreements and to require repayments of our deposits in any event of defaults by our suppliers. Termination of our rights to recall our advances has indicated that these advances will only be recovered through delivery from our suppliers which could range from one to four years. Accordingly, advances that can only be recovered after one year are similar to long-term assets and should be classified as non-current. Accordingly, RMB439.6 million of “current assets — advances to suppliers” as of December 31, 2009 has been reclassified to “non-current assets — long-term prepayments” in the comparative figures consistent with the presentation as of December 31, 2010.

The risk of loss arising from non-performance by or bankruptcy of the suppliers is assessed prior to making the deposits and credit quality of the suppliers is continually assessed. If there is any deterioration in the creditworthiness of the suppliers, we will seek to recover the advances from the suppliers and provide for losses on advances which are akin to receivables in cost of revenues because of the suppliers’ inability to return the advances. A charge to cost of revenues will be recorded in the period in which a loss is determined to be probable and the amount can be reasonably estimated. We recorded a charge to cost of revenues of RMB42.0 million, RMB234.7 million and RMB0.1 million (US$18,000), for the years ended December 31, 2008, 2009 and 2010, respectively, to reflect the probable loss arising from the suppliers’ failure to perform under the contracts. In the event that we have disputes with any of our suppliers and we are unable to reach an agreement on terms acceptable to us, we may not be able to recover our prepayments made to such suppliers.

Consolidated Results of Operations

Since all of our revenues are derived from the sale of PV products instead of the delivery of services, we presented our net revenues and cost of revenues for all product sales on a combined basis in accordance with U.S. GAAP. We believe that this presentation provides sufficient information in assessing our operating and financial performance. The following table sets forth our summary consolidated statements of operations for the periods indicated:
