Key location will expand company's presence in German market MARLBORO,
Mass. and BERLIN, Oct 26, 2009

(BUSINESS WIRE) -- Evergreen Solar, Inc. (NasdaqGM: ESLR), a
manufacturer of String Ribbon(TM) solar power products with its
proprietary, low-cost silicon wafer technology, today announced that
it has opened a new European headquarters in Berlin, Germany, further
increasing the company's presence in the German market. Evergreen
Solar began its European operations in 2002 and became a fully-
registered German company in 2004. Since that time European sales have
grown nearly 20 times, equivalent to a 180% compound annual growth
rate. The new Berlin headquarters will help the company keep pace with
the rapid business growth in the European market, particularly in
Germany, a country featuring notable incentives for commercial and
residential solar installations. The new headquarters is located at
Wallstrasse 65, 10179 Berlin.

"Berlin is an ideal location for us to establish our European
headquarters," said Peter Rusch, Managing Director of Evergreen Solar
GmbH and Vice President of Sales for Evergreen Solar, Inc. "Our
excellent products and strong relationships with customers have
allowed us to establish ourselves very quickly as a leader across the
European market." Evergreen Solar produces high output solar panels
that are the most environmentally friendly of any silicon-based panel.
They have the smallest carbon footprint with the quickest energy
payback of any silicon based panels in the industry. "Evergreen
Solar's panels produce more electricity and less impact on the
environment than any other silicon based panel," Rusch said. "If you
want to judge the performance of a panel the delivery of kilowatt
hours per kilowatts installed is the best measure. From an ecological
impact of a solar panel, the carbon footprint and energy payback are
the most important factors. That's what stands behind our slogan: More
electricity, less impact.

" The European headquarters is in addition to the company's worldwide
headquarters in Marlboro, Mass., USA. The company also has a sales
office for the Asia Pacific Region in California, as well as
manufacturing plants in Devens, Mass., Midland, Michigan and one
currently under construction in Wuhan, China. About Evergreen Solar,
