Dartmouth Building Supply (DBS) of North Dartmouth, Mass., has completed one of the region's largest private solar energy projects. On its manufacturing facilities, also in North Dartmouth, the company has installed a photovoltaic grid system consisiting of 960 solar panels.

The panels will produce 201,600 kilowatts of electricity annually, which is enough to provide about 80% of DBS's manufacturing facilities'power needs. Unused power generated on weekends will be sold back to the power grid, the company said.

"Investment in solar energy represents our ongoing commitment to long-term growth, cost containment, and leadership in Green technology," said president Joseph Delgado.

DBS said the project qualified for financial rebates granted through the Massachusetts Renewable Energy Trust and will further receive federal energy tax credits that reduce the firm's investment cost and payback period.

The project was designed and managed by Solar Installation Limited, a division of Munro Electric, in Brockton, Mass.
