Massachusetts has an SREC market – essentially, SRECs are credits for producing solar energy. Utilities will buy these SRECs from homeowners, generating significant income (sometimes $1,000s of dollars), yearly.

Net Metering is Available in Massachusetts

Massachusetts allows net metering, which is the ability to sell excess power your solar panels produce back to the electric grid. During the summer, many homeowners accrue significant credits on their electric bill, which then can heavily offset energy bills during the winter.
