Solar power in Massachusetts

Solar power in Massachusetts has been increasing rapidly, due to Section 1603 grants for installations that began before December 31, 2011, and the sale of SRECs for $0.30/kWh, which allows payback for the system within 5 or 6 years, and generates income for the life of the system. For systems installed after December 31, 2011, and before December 31, 2016, the 30% tax grant becomes a 30% tax credit.
