24,600-panel installation in Apulia, Italy, is company’s largest to date

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 a five-megawatt power plant in Apulia, Italy, that uses Evergreen Solar panels is now online. It is the largest installation of Evergreen Solar panels in the company’s history.

The project, which was designed and installed by Italian project developer Greenvision, has a total surface area of 100,000 square meters and uses 24,600 Evergreen Solar ES-A series String Ribbon solar panels. It will provide enough electricity to power approximately 2,400 homes and will prevent more than 3,000 tons of carbon dioxide emissions annually, the equivalent of planting approximately 75,000 trees. The solar power plant is funded by Enia Solaris, a joint venture of two Italian-based companies, Enia SpA and Ata Group.

“This is a milestone project for Evergreen Solar as we continue to expand our company’s global footprint with the largest installation in company history,” said Scott Gish, Evergreen Solar’s vice president of sales and marketing. “Italy is an important and growing market for solar power because of the country’s high amount of sunlight. Our solar panels are particularly well liked as they deliver the most electricity with the smallest carbon footprint of any silicon-based panel.”

"The Apulia solar park was our highest-profile project in 2009," said Carlo Ghiglieni, project manager for Greenvision. "We chose Evergreen Solar panels for this installation because of the product’s reputation for having one of the best power tolerances and its proven reliability."
