PRESS RELEASE

Evergreen Solar Reports Audited Fourth Quarter Financial Results

Marlboro, Massachusetts, March 9, 2011 – Evergreen Solar, Inc. (NasdaqCM: ESLR), a manufacturer of String Ribbon^® solar power products with its proprietary, low-cost silicon wafer technology, today announced audited financial results for the fourth quarter ended December 31, 2010.

Revenues for the fourth quarter of 2010 were $89.3 million, up 3.2% sequentially compared to third quarter revenues of $86.5 million. Average selling price for the fourth quarter of 2010 was $1.90 per watt, down approximately 6% from $2.02 per watt recorded in the third quarter of 2010.

Gross margin for the fourth quarter of 2010 was -84% compared to 7.5% in the third quarter of 2010. The decrease in gross margin resulted primarily from the write-down of prepaid inventory resulting from the decision to close the Devens manufacturing facility and the countervailing duties assessed on the Company’s imported aluminum frames, as previously disclosed.

Operating loss for the fourth quarter of 2010 was $399.1 million, compared to $22.7 million for the third quarter of 2010. Operating loss in the fourth quarter of 2010 increased sequentially from the third quarter due mainly to the inventory write-down and the impairment of long-lived assets totaling $377.5 million in connection with the Company’s decision to close its Devens manufacturing facility. Operating loss for the third quarter of 2010 included a $6.4 million charge relating to the write-off of a receivable associated with a Korean customer and a decrease in royalty revenue, offset by a decrease in manufacturing costs.

Net loss for the fourth quarter of 2010 was $411.0 million compared to $27.2 million in the third quarter of 2010. Net loss for the fourth quarter includes the aforementioned write-down and impairment charges of $377.5 million. Net loss for the third quarter of 2010 included the previously disclosed charge to accounts receivable and foreign exchange gains of $6.3 million.

Cash and cash equivalents as of December 31, 2010 was $68.4 million, including restricted cash of $6.8 million.

Michael El-Hillow, President and Chief Executive Officer commented, “The decision to close the Devens facility was the direct result of rapid and dramatic changes in the underlying market that have taken place since the facility first began operations. We believe we are now better positioned to facilitate a rapid transition to a strategic supplier of low cost multi-crystalline silicon wafers by virtue of our proprietary wafer technology.” He added, “Our Devens employees exceeded many of management’s expectations and for this, they have our deepest appreciation.”

Mr. El-Hillow concluded by sharing his views about the opportunities in Evergreen Solar’s future. “Today, we are focusing all of our energies and resources in delivering an industry standard size and high performance low cost wafer. We believe this is the best strategic direction for the Company as we leverage our proprietary manufacturing and product technology to produce String Ribbon^™ wafers at a total silicon and non-silicon cost of about $0.25 per watt in 2013. We are encouraged by the early

feedback received from companies that have been sampling our industry standard size wafers. Pilot line production up to 25 megawatts should be on-line in China toward the end of this year. In-depth negotiations to obtain significant financing for expansion and customer support for our industry standard wafer are attracting very strong interest and we are expecting to have more details to share on our progress by early summer.”

Safe Harbor Statement

This press release includes statements regarding expectations, beliefs, strategies, goals, outlook and other non-historical matters. Any such statements are forward-looking statements made pursuant to the safe harbor provisions of Section 21E of the Securities Exchange Act of 1934. Forward-looking statements include but are not limited to statements about preliminary financial results, the timing of the shutdown of the Company’s Devens facility, the size of any non-cash charges and the estimated cash costs associated with a shutdown. These forward-looking statements are neither promises nor guarantees and are subject to a number of risks and uncertainties that could cause actual results to differ materially from the Company’s current expectations. Factors that could cause or contribute to such differences include, but are not limited to potentially higher than expected costs associated with the shutdown of the Company’s Devens facility; the significant additional work required to develop and commercialize our industry standard size and high performance low cost String Ribbon wafer; technological challenges and factors beyond our control, such as silicon pricing, that impact our ability to achieve our wafer cost target of $0.25 per watt in 2013; the difficulty we face in raising funding for our pilot production line operation and the significant further funding required to accomplish our commercial manufacturing expansion; our potential inability to supply the significant volumes of wafers required in the near-term for potential customers and partners to qualify our new industry standard size String Ribbon wafers; and the uncertainty for the entire PV solar industry in light of significant worldwide capacity expansions which may exceed worldwide demand for PV solar products as a result of various factors including potential significant reductions in subsidies in key markets like Germany. Further details regarding these and other important risk factors can be found in the Company’s public filings with the SEC (www.sec.gov), including its Form 10-K for the fiscal year ended December 31, 2010 and its Registration Statement on Form S-4 (as amended) originally filed on December 6, 2010.
