This 180-panel system is the largest in Central Mass., and one of the largest residential installations in the entire state. It has Canadian Solar 255-watt panels and four Solectria PVI-7500 string inverters. The carbon offset by the customer’s clean energy is equivalent to more than eight cars being taken off the road for a year.
