Solar power in Boston, Massachusetts

You can't get much luckier in Boston with solar incentives. Besides the 30% federal tax credit and net metering Massachusetts offers an array of incentives making solar more affordable than ever. Despite solar already being a no brainer there is also an excellent SREC market in Massachusetts. SREC's on a standard 5kW system in Massachusetts will put about $1,600 into your pocket every year.

The way SREC's work is that utilities are mandated by law to provide a certain percentage of their power from solar power. If utilities fail to provide enough SREC certificates to the government they are heavily fined. Each Solar Renewable Energy Credit (SREC) Is evidence of 1mWh of solar production and these certificates are purchased by your utility in order for them to meet their targets. Each SREC is worth about $250-$300 and with a 5kW system producing 6 SREC's per year that's about $1,600 in your pocket every year!
