Trina Solar Announces First Quarter 2011 Results

Changzhou, China — May 17, 2011 — Trina Solar Limited (TSL) (“Trina Solar” or the “Company”), a leading integrated manufacturer of solar photovoltaic products from the production of ingots, wafers and cells to the assembly of PV modules, announced today its financial results for the first quarter of 2011.

First Quarter 2011 Financial and Operating Highlights

•

Solar module shipments were approximately 320 MW for the first quarter of 2011, compared to the Company’s previous guidance of slightly higher than the approximately 351 MW shipped in the fourth quarter of 2010, representing a decrease of 8.7% sequentially and an increase of 66.4% year-over-year

•

Net revenues were $550.9 million, a decrease of 14.2% sequentially and an increase of 63.5% year-over-year

•

Gross profit was $151.3 million, a decrease of 25.0% sequentially and an increase of 45.1% year-over-year

•

Gross margin was 27.5%, compared to the Company’s previous guidance of mid to high 20s in percentage terms, compared to 31.4% in the fourth quarter of 2010 and 30.9% in the first quarter of 2010

•

Gross margin relating to the Company’s in-house wafer production to module production was 32.2%, compared to the Company’s previous guidance of approximately 30%

•

Operating income was $84.5 million, compared to $145.1 million in the fourth quarter of 2010 and $76.0 million in the first quarter of 2010

•

Operating margin was 15.3%, compared to 22.6% in the fourth quarter of 2010 and 22.6% in the first quarter of 2010

•

Net income was $47.7 million, which included a net foreign currency exchange loss of $24.1 million, compared to net income of $145.3 million in the fourth quarter of 2010 and $44.5 million in the first quarter of 2010

•

Earnings per fully diluted American Depositary Share (“ADS”) were $0.63, compared to $1.87 in the fourth quarter of 2010 and $0.66 in the first quarter of 2010

“Amidst a challenging macro environment and winter season conditions, we maintained relatively strong shipment volumes in the first quarter,” said Mr. Jifan Gao, Chairman and CEO of Trina Solar.

“Despite decreased sequential demand linked to Italy’s solar regulatory revisions, we realized notable market share gains in Germany, the rest of Europe and on a global basis. This included high-profile customer additions in Europe, North America and Asia, which we believe reflect the strength of our leading brand, the quality and performance of our products and the increased localized service we provide to our customers.

Building off our quality-performance and manufacturing efficiency leadership, in 2011 we are increasingly focused on elevating our technology innovation, customer orientation and corporate social responsibility advantages. As we further differentiate our brand, we believe such enhancements are directly responsible for our recent successes in supplying large commercial and utility-scale segments in Italy, Germany and the United States.

We are also pleased with our efforts and progress on environmental health and safety. In January 2011, we received TUV’s globally-recognized Occupational Health & Safety Management System OHSAS18001 certification. We were also ranked the No. 2 Global PV Manufacturer for Environmental and Social Performance on SVTC’s 2011 Solar Company Scorecard, which reflects our commitment to the sustainable development of our company and the solar industry.

As we continue to diversify our customer base across geographic regions, we are excited to announce the opening this month of our sales and business development office in Sydney to support our growing base of Australian customers. This new office will also help us seek out business development opportunities in the fast growing Australian solar PV market.

Lastly, in our efforts to raise our organizational capabilities to deliver innovative market-driven solutions, product value and world-class customer service, we are happy to welcome Mr. Mark Kingsley, who has been appointed to our newly-created Chief Commercial Officer position.”

First Quarter 2011 Results

Net Revenues
Net revenues in the first quarter of 2011 were $550.9 million, a decrease of 14.2% sequentially and an increase of 63.5% year-over-year. Total shipments were 320.4 MW, compared to the Company’s previous guidance of slightly higher than the approximately 351 MW shipped in the fourth quarter of 2010 and 192.6 MW in the first quarter of 2010. The sequential decrease in total shipments was primarily due to demand uncertainties linked to Italy solar investment policy revisions announced in March 2011.

Gross Profit and Margin
Gross profit in the first quarter of 2011 was $151.3 million, compared to $201.8 million in the fourth quarter of 2010 and $104.2 million in the first quarter of 2010.

Gross margin was 27.5% in the first quarter of 2011, compared to the Company’s previous guidance of mid to high 20s in percentage terms. The first quarter gross margin compares to 31.4% in the fourth quarter of 2010 and 30.9% in the first quarter of 2010.

Gross margin relating to the Company’s in-house wafer production to module production was 32.2% in the first quarter of 2011, compared to the Company’s previous guidance of approximately 30%, and 36.5% in the fourth quarter of 2010. The sequential decline was primarily due to lower average selling price.

Operating Expense, Income and Margin
Operating expenses in the first quarter of 2011 were $66.8 million, an increase of 17.8% sequentially and 136.5% year-over-year. The Company’s operating expenses represented 12.1% of its first quarter net revenues, an increase from 8.8% in the fourth quarter of 2010 and 8.4% in the first quarter of 2010. The sequential and annual percentage increases were primarily due to continued expansion of the Company’s global management structure to meet its strategic growth objectives, and increased investment in Research and Development initiatives, offset by expense control measures implemented in 2010. Operating expenses in the first quarter of 2011 also included $1.6 million in share-based compensation expenses, compared to $1.8 million in the fourth quarter of 2010 and $1.0 million in the first quarter of 2010.

As a result of the foregoing, operating income in the first quarter of 2011 was $84.5 million, compared to $145.1 million in the fourth quarter of 2010 and $76.0 million in the first quarter of 2010. Operating margin was 15.3% in the first quarter of 2011, compared to 22.6% in both the fourth quarter of 2010 and the first quarter of 2010.

Net Interest Expense
Net interest expense in the first quarter of 2011 was $6.7 million, compared to $6.6 million in the fourth quarter of 2010 and $9.0 million in the first quarter of 2010. The year-over-year decrease was primarily due to decreased average short-term borrowing balances and the increase in interest income as a result of higher cash and cash equivalents in bank accounts.

Foreign Currency Exchange
The Company had a foreign currency exchange loss of $24.1 million in the first quarter of 2011, which was net of changes in fair value of derivative instruments. This compares to a net gain of $25.3 million in the fourth quarter of 2010 and a net loss of $14.5 million in the first quarter of 2010. This net loss was primarily due to the loss from foreign currency forward contracts used by the Company to hedge its foreign currency risk exposure, which was partially offset by gains from the appreciation of the Euro against U.S. dollar.

The Company continued foreign currency hedging during the first quarter of 2011 using foreign currency forward contracts between the Euro and the U.S. dollar, with the goal of mitigating the effects of exchange rate volatility.

Income Tax
The effective tax rate for the Company during the first quarter of 2011 period was 20.54%, due to the fact that one major subsidiary in China is under the renewal process of obtaining a preferential tax rate from local tax authority. This compares to 13.4% for fiscal year 2010, at which time the company benefited from the preferential tax rate of High and New Technology Enterprises status.

Net Income and EPS
Net income was $47.7 million in the first quarter of 2011, a decrease from $145.3 million in the fourth quarter of 2010 and an increase from $44.5 million in the first quarter of 2010. The net foreign currency exchange loss included in net income was $24.1 million in the first quarter of 2011, compared to a net foreign currency exchange gain of $25.3 million in the fourth quarter of 2010 and a net foreign currency exchange loss of $14.5 million in the first quarter of 2010, respectively.

Net margin was 8.7% in the first quarter of 2011, compared to 22.6% in the fourth quarter of 2010 and 13.2% in the first quarter of 2010.

Earnings per fully diluted ADS were $0.63 in the first quarter of 2011. The effects of the net first quarter foreign currency exchange net loss was approximately $0.30 per fully diluted ADS.

Financial Condition
As of March 31, 2011, the Company had $554.6 million in cash and cash equivalents and restricted cash and a working capital balance of $769.9 million. Total bank borrowings stood at $448.9 million, of which $295.7 million were long-term borrowings. The Company reduced its short-term borrowings by $5.4 million to approximately $153.3 million as of March 31, 2011.

Shareholders’ equity was $1.22 billion as of March 31, 2011, an increase from $1.17 billion at the end of the fourth quarter of 2010.

Second Quarter and Fiscal Year 2011 Guidance

For the second quarter of 2011, the Company expects to ship between 430 MW to 450 MW of PV modules.

The Company expects its gross margin relating to its in-house wafer production to module production to be in the mid 20s in percentage terms during the second quarter of 2011. The Company believes its overall gross margin, taking into account wafer and cell requirements outsourced to third party suppliers to meet demand in excess of its internal capacity, for the second quarter will be in the low 20s in percentage terms. Such guidance is based on the exchange rate between the Euro and U.S. dollar as of May 17, 2011. For the full year of 2011, the Company expects total PV module shipments between 1.75 MW to 1.80 GW, representing an increase of 65.6% to 70.3% from 2010.

Operations and Business Outlook

Non-Silicon Cost
In the first quarter of 2011, the Company’s non-silicon manufacturing cost for its core raw materials to module production was approximately $0.73 per watt, a sequential decrease of $0.01. By the end of 2011, the Company expects its non-silicon manufacturing cost to decline to approximately $0.70 through the continuation of technology and manufacturing process improvements involving proprietary processes for ingot, wafer, cell and module manufacturing, higher cell conversion efficiencies, and supply chain and logistics management initiatives currently under testing or development.

Silicon Procurement
Through its diversified range of short, medium, and long-term supply contracts, the Company will continue to maintain competitive silicon costs relative to the current market price.

2011 Capacity Expansion
As of April 30, 2011, the Company’s annualized in-house ingot and wafer production capacity was approximately 750 MW and its PV cell and module production capacities was approximately 1.6 GW.

To meet expected demand for its PV solar modules, the Company expects to raise its annualized in-house ingot and wafer production capacity and PV cell and module production capacity to approximately 1.2 GW and 1.9 GW, respectively, in the second half of 2011, based on actual manufacturing yield.

* Notes to unaudited consolidated financial statements:

In July, 2010 the Company was made aware of a contingent liability in the form of legal action brought against its Hong Kong subsidiary, Top Energy International Limited (“TEI”). The action stems from a 2008 transaction involving the exchange of silicon materials and subsequent claims involving material qualities. Given the claims were made outside contractual time limitations and upon disputed testing methodology, the Company believes the claimant would be unlikely to prevail. If, however, the claimant proved successful in such legal actions, the Company may become obligated to incur damages of up to approximately $4.0 million.
