Evergreen Solar's CEO Richard M. Feldt Named 2005 Cleantech Leader of the Year; CEO's Vision and Execution Earns Evergreen Solar Recognition.

MARLBORO, Mass. -- Evergreen Solar, Inc. (Nasdaq: ESLR), a manufacturer of solar power products with its proprietary, low-cost String Ribbon(TM) wafer technology, today announced its president and chief executive officer, Richard M. Feldt, has been named the 2005 Cleantech Leader of the Year by Cleantech Venture Network(TM), a membership organization bringing insight, opportunities and relationships to investors, entrepreneurs and service providers interested in clean technology.

The Cleantech Leader of the Year is awarded to an industry professional who has demonstrated exceptional leadership in adding credibility or resources to the cleantech industry. Feldt received the award at the Cleantech Venture Forum(TM) IX in San Francisco, CA on Wednesday, March 22, 2006.

"Under Rick Feldt's stewardship, Evergreen Solar has grown rapidly and is emerging as a true leader in the alternative energy space," said Nicholas Parker, co-founder and chairman of the Cleantech Venture Network. "This award recognizes Rick and the entire Evergreen Solar team for their substantial achievements over the past year and their comprehensive efforts to accelerate the adoption of solar power."

Feldt joined Evergreen Solar in December 2003 and has orchestrated the Company's transition from a research and development organization to an emerging manufacturer in the solar power industry leveraging unique, proprietary technologies. Evergreen's String Ribbon technology is substantially more efficient in the use of silicon than conventional sliced crystalline technologies. In fact, its new thin ribbon product will generate approximately twice as much power per pound of silicon than conventional methods.

Under Feldt's leadership the past two years, Evergreen Solar has increased its revenues by more than 370 percent from $9.3 million for full year 2003 to more than $44 million for full year 2005. Through its EverQ joint venture, the Company is now in the process of constructing a new 30MW manufacturing plant in Thalheim, Germany that will serve as an additional catalyst for its growth in the years ahead.

"I would like to thank Cleantech for this honor, and I accept it on behalf of the entire Evergreen organization," said Richard M. Feldt. "Evergreen Solar has made substantial strides in both R&D and manufacturing to further reduce the cost of solar power. Our success to date is the result of the coordinated efforts of an outstanding group of people. I am confident that, working together, we will be able to accomplish even greater goals in 2006 and beyond."
