Marlboro, Massachusetts, April 23, 2007 - Evergreen Solar, Inc. (Nasdaq: ESLR), a manufacturer of solar power products with its proprietary, low-cost String Ribbon' wafer technology, today unveiled its major new corporate re-branding program. The all- encompassing program, including its novel "Think Beyond" tag line and vibrant new logo and color scheme, will touch every point of Evergreen's contact with its customers and stakeholders.


"Evergreen's status as a global leader in developing cutting-edge solar technology has compelled us to put a distinctive new face on the entire company," said Dr. Terry Bailey, Evergreen senior vice president of marketing and sales. He noted that Evergreen's original identity, symbolized by an evergreen tree and the sun, was important in establishing the company as a rising star in the then-nascent solar industry. "As Evergreen continues its remarkable growth, our new corporate identity and 'Think Beyond' positioning better capture the essence of our dynamic, innovative company," he said.

The scope of the new brand identity is extensive, cutting across all of the company's communication channels including customer relations, marketing and advertising. Bailey said Evergreen's recently-enhanced customer support program is a direct outgrowth of the re-branding effort. "We reached out, spoke extensively with our customers and listened to their needs before building a program that we trust will exceed their expectations. Bailey noted that a key component in Evergreen's success is its constant challenge to employees to always look for new ways to improve the company - to "think beyond" the conventional. "They continually meet that test by developing better ways to refine our technology, upgrade our production efficiency, and support our customers," he said. Evergreen customers will begin to see the distinctive new corporate logo on the company's solar panels in the coming weeks. It is also prominently featured in the company's new, enriched marketing program.
