Evergreen Solar just announced the successful installation of a 100KW system to provide power for Boston Sand and Gravel. The system, which utilizes 500 Evergreen Solar panels and Solectria Renewable Inverter and custom engineered mounting system , provides enough energy to meet two thirds of the energy needs for the company’s maintenance facility. The installation is expected to pay for itself in 5 1/2 years.

In a company press release, executives from both companies commented on the deal:

“This is not only a significant solar installation for Boston Sand & Gravel, it’s a milestone for the City of Boston as it is the first 100kw plus project to be installed under the Commonwealth Solar and Solar Boston initiatives of both Governor Patrick and Mayor Menino,” said Terry Bailey, Evergreen Solar’s senior vice president of sales and marketing. “Boston Sand & Gravel’s choice to use Evergreen Solar’s panels will not only show immediate results in performance as our panels deliver more electricity (kilowatt hours per kilowatts installed) throughout the day than any crystalline silicon panel, but it will also help the company accomplish its carbon goals since our panels have both the smallest carbon footprint and the quickest energy payback of any silicon based solar panel in the business.”

“Boston Sand & Gravel is excited and pleased to complete our solar installation,” Dean Boylan, President of Boston Sand & Gravel said. “It is a cornerstone of our Green Plan through which we will support our customers with materials for green construction while reducing our energy consumption in the production of those materials.”
