About solar in Massachusetts

Massachusetts squeezes more solar out of its rooftops than almost any state in the country: about 4,800 megawatts are installed, more than 13% of households already have panels on the roof — seventh in the nation for residential solar — and an industry of more than 11,000 solar workers keeps it growing. The state's rebuilt SMART 3.0 program aims to add another 3.5 gigawatts of solar and storage, a build-out forecast to save every ratepayer in the state about $313 million a year.
Two programs do the heavy lifting for homeowners. Under net metering, the extra power you send to the grid earns credits worth nearly the full retail rate, and unused credits roll forward from month to month; home systems of 25 kW and under sit outside the program's capacity caps. On top of that, the SMART program pays a separate per-kilowatt-hour incentive for the solar you generate — small home systems get a fixed rate locked in when they qualify, with an extra adder for low-income households.
With some of the highest electricity prices in the country, every self-generated kilowatt-hour goes further in Massachusetts. Compare the installers below, and browse our solar energy resources for guides to sizing a system, pairing it with a battery, and stacking SMART with net metering.
