Marlboro, Massachusetts, June 18, 2007 - Evergreen Solar, Inc. (Nasdaq: ESLR), a leading manufacturer of solar power products with its proprietary String Ribbon' wafer technology, today held an "International Business Summit" in Leipzig, Germany. Evergreen customers from three continents joined members of the Company's senior management team for the day-long event.

"Our Business Summit was a terrific success," said Dr. Terry Bailey, Evergreen's Senior Vice President of Marketing and Sales. "With our continued rapid expansion, Evergreen is now participating in an ever-growing number of solar markets around the world. Our recent summit provided a forum for participants to analyze those markets and discuss marketing strategies to ensure continued growth for our partners and Evergreen."

A primary focus of summit participants was Evergreen's customer support program, launched earlier this year as part the Company's extensive rebranding campaign. Evergreen, in close collaboration with its customers, developed the support program after reaching out to them, discussing their needs, and providing them with new and better tools.

"Our program is continually evolving as Evergreen maintains an ongoing dialogue with customers to improve our products, distribution network and marketing opportunities," Dr. Bailey said. "During our summit discussions we were pleased to learn that they rank our support program as one of the very best in the solar industry."

The summit was held in conjunction with the June 19 opening of EverQ 2, the 60-MW manufacturing plant in nearby Thalheim, Germany, that manufactures Evergreen-branded solar panels exclusively. The new facility's production capacity will nearly triple EverQ's production of Evergreen-branded solar panels to approximately 100 MW. EverQ is an equal partnership of three global leaders in the solar power industry, including Evergreen Solar, Q-Cells AG (Germany), and Renewable Energy Corporation ASA (Norway).

Summit participants will join Evergreen for the opening of the new EverQ plant in Thalheim, where they will view the Company's cutting-edge String Ribbon' technology at work. Later this week, many summit attendees will travel with Evergreen to Intersolar 2007, the international solar exhibit in Freiburg, Germany.
