Commenting on the quarter, Allen Wang, CEO of China Sunergy remarked:

“During the quarter we began commercial production of our selective emitter cells and increased production levels beyond what we had guided for in November. At the same time we expanded our presence in Europe by signing noteworthy sales agreements and opening an office in Munich. I have been pleased by the response many of our customers have shown towards our high efficiency cells and believe that these products will help drive revenue growth in Europe’s new solar markets.”

Fourth Quarter and Recent Operational Highlights:

• Commercial mass production of high-efficiency selective emitter cells (“SE”) commenced in mid-November. A total of 2.4 MW was produced with 0.8MW shipped during the fourth quarter.

• Average SE cell efficiency continued to improve from 16.5% in the third quarter to an average efficiency of 17.3% in the fourth quarter. A maximum conversion efficiency of 18.2% was achieved on pilot runs of selective emitter cells during November 2007.

• The signing of the following agreements for 2008; a 30MW solar cell agreement with aleo solar, a 25MW sales agreement with Canadian Solar and a 10.2MW agreement with asola.

• Revenue from overseas grew from 20.3% for the full-year 2006 to 35.7% for the full-year 2007.

• In the quarter we began developing HP cells, a more efficient version of our current P-type cells. The limited pilot run of 0.3 MW in the fourth quarter achieved an average conversion efficiency rate of over 17%, higher than the 16.1% achieved with P-type cells during the same period.

“During 2008 we will focus on improving margins and profitability by deriving a greater proportion of overall revenues from our high efficiency solar cell products,” continued Mr. Wang. “We remain confident that as we expand production of our SE and HP products, margins can improve further during the coming year. Our confidence in achieving this objective is based on strong indications of customer preference for our high-efficiency cells.”

Key Sales Agreements

During the quarter, the Company recently signed significant sales contracts with:

• aleo solar AG (“aleo”), a leading German solar module manufacturer, to supply at least 30 MW of high quality silicon solar cells in 2008.

• Canadian Solar Inc., a leading China-based module manufacturer, for a total volume of 25MW of solar cells for delivery in 2008.

• asola, a reputable German module manufacturing company to supply a total volume of 10.2MW of solar cells during 2008.

Technological Developments

During the quarter the Company continued to make significant progress with the production of its high efficiency cell technology.

Average selective emitter efficiency continued to improve from 16.5% in the third quarter to 17.3% in the fourth quarter of 2007. A maximum conversion efficiency of 18.2% was achieved on pilot production runs during November 2007.

5

The Company is now enhancing its current P-type cell production facilities by converting existing lines to high-efficiency P-type (or “HP”) lines. HP cells are a more efficient version of our standard P-type cells and achieve a higher conversion efficiency ratio as a result of an enhanced production process. HP cells of mono-crystalline 125 millimeter achieved an average conversion efficiency rate of over 17% on a 0.3 MW limited pilot run during the fourth quarter, and maximum conversion efficiency of 17.5%.

The development of the Company’s patented N-type cells continues to move along smoothly. During 2008, China Sunergy intends to invest US$8 million in an R&D centre in Shanghai aimed at further developing N-type and other types of high efficiency cells. The center is expected to house 100 research employees. Construction of the center is scheduled to be completed by early 2009.

Fourth Quarter 2007 Financial and Business Review

Revenue, shipment and production

During the fourth quarter of 2007, revenues grew 1.1% on a year-over-year basis, and increased 46.0% compared to the previous quarter to US$71.5 million.

Sales from solar cells, polysilicon, and modules accounted for 94.7%, 1.0% and 4.3%, of total revenue respectively. Shipments, including 0.8MW for module sales, amounted to approximately 23.2 MW, compared to 21.3MW during the fourth quarter of 2006 and 16.6MW during the third quarter of 2007.

Revenue and Shipment Comparison between Q4 and Q3 2007

	Q4		Q3
	Volume*	Value (US$mm)	Volume*	Value (US$mm)
Core cell sales	22.4	67.7	16.2	46.3
Polysilicon sales	0.8	0.7	4.5	1.1
Module sales	0.8	3.1	0.4	1.5

* All volumes are expressed in MW except for Polysilicon sales expressed in metric tons.

During the fourth quarter the Company increased its quarter-on-quarter sales of core cell products by 46.1% as compared to the previous quarter. The percentage of overall cell sales in overseas markets declined in percentage terms from 47.7% to 40.6% compared to the previous quarter, particularly in Europe where sales declined from 42.7% to 35.0% sequentially even though in absolute terms cell sales to Europe increased from 6.7 MW to 7.6 MW sequentially.

In terms of MW volumes, mono-crystalline 125-millimeter cells accounted for a proportion of overall production and cell sales at 57.1% and 57.5% (in terms of volume) respectively as we increased production and sale of multi-crystalline to cater for the increasing demands of European customers.

Gross profit, gross margin and Average Selling Price (“ASP”)

Gross profit for the quarter was US$4.6 million, which led to a blended gross margin of 6.4%, up from 2.1% in the third quarter, as a result of the gross margin contribution from high efficiency cell products.

Margin Breakdown

	Gross margin
	Q4		Q3
Core cell sales	6.3	%	1.5	%
Polysilicon sales	12.2	%	27.0	%
Module sales	7.8	%	0.8	%
Blended	6.4	%	2.1	%

The sequential gross margin expansion on core cell sales from 1.5% to 6.3% was mainly attributed to higher ASP as a result of a greater proportion of sales coming from high-efficiency cells.

Blended ASP for the fourth quarter rose from US$2.85 per watt in the previous quarter to US$3.02 per watt due to strong product demand and the strengthening of the Renminbi.

Wafer costs continued to account for a large portion of overall manufacturing costs. In the fourth quarter, wafer costs rose to US$2.54 per watt compared to US$2.45 per watt in the third quarter. Wafer costs per watt as a percentage of total production costs per watt increased from 89.2% in the third quarter to 90.1% in the fourth quarter. Other production costs, which mainly consisted of other raw materials, labor, depreciation and utilities, were US$0.28 per watt and largely the same as the first three quarters of this year.

SG&A and net income

Our SG&A expenses increased from US$4.2 million to US$5.3 million sequentially mainly due to an increase in professional expenses.

Due primarily to higher gross margin, the Company reduced its sequential operating loss to US$1.2 million. This compares to an operating profit of US$11.4 million and an operating loss of US$3.6 million for the fourth quarter 2006 and third quarter of 2007, respectively.

With higher gross margin, the Company reduced its sequential net loss for the quarter to US$2.3 million.

Balance sheet

As of December 31, 2007, the Company had cash and cash equivalents of US$60.5 million. Net operating cash outflow for the fourth quarter was US$5.3 million. In the fourth quarter of 2007 depreciation was US$1.2 million and capital expenditures were US$7.0 million. The capital expenditures were related to prepayments made for equipment relating to the phase III expansion of our SE lines.

Wafer costs continued to account for a large portion of overall manufacturing costs. In 2007, wafer costs rose to US$2.43 per watt compared to US$2.42 per watt in 2006. Wafer costs per watt as a percentage of total production costs per watt declined from 91.8% in 2006 to 89.9% in 2007 due to improvements in operational efficiency. Other production costs, which mainly consisted of; other raw materials, labor, depreciation and utilities, were US$0.28 per watt in 2007.

SG&A and net income

Our SG&A expenses were US$15.3 million for 2007, compared to US$10.9 million in 2006 mainly due to the expansion of the business and additional expenses relating to our operation as a public company after our initial public offering in May 2007.

The Company incurred an operating income of US$0.16 million for 2007. This compares to an operating profit of US$15.2 million in 2006. Full year net loss was US$4.9 million, compared to net profit of US$11.8 million in 2006, mainly due to lower gross margins in 2007. GAAP basic and diluted net loss attributable to holders of ordinary shares was US$0.21 per ADS in 2007 compared to a GAAP basic and diluted net loss of US$2.16 per ADS in 2006.

Balance sheet

As of December 31, 2007, the Company had cash and cash equivalents of US$60.5 million. Net operating cash outflow for 2007 was US$62.8 million. In 2007 depreciation was US$4.3 million and capital expenditures were US$16.8 million.

Commenting of the financial results, Kenneth Luk, CFO of China Sunergy, said:

“We intend to ensure that margin improvements translate into profitability during the coming year. Based on the margins we are achieving on our SE and HP type cells I believe that we will be able to achieve a blended gross margin of at least 7.5% during the first quarter of 2008. In addition, a core focus is on implementing strict cost control measures and better cash management to ensure that we are able to maximize internal cashflow and liquidity during 2008 and that at an operational level we should be cashflow positive during the first quarter of 2008.”

Outlook

Given the success of our pilot HP cell production run, the company has decided to convert all of its four existing P-type lines to HP. This conversion will be completed by the end of the first half of 2008. In addition, all four of our new SE lines are expected to be in mass production during the fourth quarter of 2008. In the current pricing environment, we expect to achieve an additional margin improvement over traditional P-type cells of 8-10% on HP cells, and 12% on SE cells.

As a result of the conversion of P-type production lines and a delay in the delivery of equipment required for SE production lines, as well as some impact from the bad weather we experienced during the first quarter, the Company is revising its 2008 production target to 125-145 MW with approximately 65 to 85 MW expected to come from high efficiency cell products (which we define as cells that yield a higher than 17% conversion efficiency rate). This is projected to comprise of approximately 25-35 MW of SE cells and 40 – 50 MW of HP cells.

The Company anticipates its gross margin for first quarter of 2008 to be between 7.5% and 8.5%.
