Evergreen Solar Panels Chosen to Power Patriot Place

January 4, 2010

Evergreen Solar panels will provide 30% of the complex’s electrical needs

MARLBORO and FOXBOROUGH, Mass.  (December 22, 2009) -- Evergreen Solar, Inc. (Nasdaq: ESLR), a manufacturer of STRING RIBBON™ solar power products with its proprietary, low-cost silicon wafer manufacturing technology, announced today that its String Ribbon solar panels have been chosen for a 525-kilowatt installation at Patriot Place, a 1.3-million-square-foot shopping, dining and entertainment complex located adjacent to Gillette Stadium, home of the New England Patriots.

The system will supply approximately 30 percent of the power to the complex and more than 12 million kilowatt hours of electricity over 20 years. The system will eliminate an estimated 8,800 metric tons of carbon dioxide from the atmosphere each year, the equivalent of removing approximately 1,600 passenger cars from the road.

In total, more than 2,800 of Evergreen Solar’s ES-A series panels spanning the roofs of seven buildings will be used in the construction. One of the buildings that will house the panels is The Hall at Patriot Place presented by Raytheon, an award-winning sports and educational experience that is one of the highlights of Patriot Place. These panels will be visible to fans who attend games and events at Gillette Stadium and visitors to Patriot Place’s upper retail plaza.

Patriot Place, which began opening in phases in 2008, was constructed using sustainable design practices, including low-emitting construction materials and white roofs to facilitate heat island reduction. Patriot Place employs an on-site wastewater re-use system that saves millions of gallons of water annually and solar-powered trash receptacles throughout the complex that reduce waste volume and energy consumption.

“We’re thrilled that Patriot Place has chosen Evergreen Solar for this highly-visible solar installation,” said Alan King, Director Sales for the Americas. “As a company producing solar panels that deliver more electricity with less impact on the environment including the smallest carbon footprint, we feel we align perfectly with the environmental goals of Patriot Place while demonstrating the viability of solar power to the many patrons and fans traveling through this incredible complex.”

“This project is crucial to Patriot Place’s overall sustainability initiatives and we are proud to promote practical and cost-effective commercial applications of solar power,” said Brian Earley, Patriot Place General Manager. “We’re also proud to work with a local company like Evergreen Solar on such an important project.”

The solar installation is being constructed by Baltimore-based Constellation Energy’s Projects & Services Group.
