MARLBORO, Massachusetts - When the Captain Planet Foundation's "Zero-Energy Cottage," designed to show how a home can use little or no energy from utilities, debuts in the nation's Capital, the two-bedroom, two-bath house will feature solar electric panels made by Evergreen Solar. Massachusetts-based Evergreen Solar, Inc. (Nasdaq: ESLR), answered the call by the Atlanta foundation to make the 1,700 square foot vacation home a reality in time for the Atlanta Home Show in mid-April.

The unique home now moves to Washington, D.C. as part of the National Park Service's Sustainability Fair on the National Mall on May 3 and 4. The home then returns to Atlanta, where it will be on display at the Georgia World Congress Center for the American Lung Association's Annual Meeting and a six-month exhibition at Atlanta's SCITREK Museum.

"We were very happy to respond when the Captain Planet Foundation requested solar panels for the home," said Dr. Rex D'Agostino, Evergreen's Vice President of Marketing and Sales. "Captain Planet is a forward thinking foundation working to build environmental awareness, particularly among children, so it was a natural for us."

Captain Planet Foundation Executive Director Sona Chambers said, "We're pleased that Evergreen Solar came through so quickly and easily, and that they joined with us and the other environmentally progressive suppliers to make this a success." Chambers added that Captain Planet Foundation is building a Charleston-style house designed by Allison Ramsey Architects in Beaufort, S.C. Evergreen Solar's photovoltaic panels will be on the roof of that home, as well.

"It's very exciting to be building two homes that cover the range of homeowner needs, yet can demonstrate the results of intelligent, environmentally-sound construction," Chambers said. "It shows how feasible, attractive, and cost effective these homes are." Proceeds of the home sales will go to the Captain Planet Foundation, which provides funds for hands-on environmental projects for kids.

Evergreen Solar supplied panels totaling 4 kW of power for the cottage. Combined with a host of unique, environmentally-friendly designs, materials and systems, the panels are intended to produce more energy than the home actually needs, enabling the house to go "off the utility grid." The panels are produced using Evergreen's patented String Ribbon(TM) technology. This technology produces approximately twice as many solar cells per pound of silicon compared to traditional methods. This contributes to making Evergreen's overall manufacturing technology among the most environmentally friendly processes in the industry. Evergreen Solar is one of the only fully-integrated, independent PV manufacturers in the U.S - producing solar wafers, cells and panels.

"During the home's six-month exhibition at SCITREK," Chambers said, "the cottage will be used to educate the public on renewable energy and to instruct construction companies and home builders on how to build similar types of houses."
