Many homeowners are confused about how much they should expect to pay for solar on their home. While prices vary greatly based on power needs, sun exposure and choice of financing options, we’ve compiled data on the average costs that homeowners in Massachusetts could expect to pay for solar.

We also include the price that homeowners are paying on average for entire systems in our individual regional summary pages.
As solar prices have fallen and power prices have increased, Massachusetts homeowners have purchased larger and larger solar systems. In 2008, the average size of solar installations across the state was roughly 4.1 kW, and in 2015 to 2019 that number has climbed 81% to 7.4 kW.

Massachusetts Power Costs – Some of the Highest in the Country
The price of power has skyrocketed in the Bay State, and is among the highest in the U.S. Prices have increased 79% from 2004 – 2015, from 10.9 cents per kWh in 2004 to 19.52 cents per kWh in 2015. You can learn more about current power prices in Massachusetts here.
Power price increases like these are a huge part of the appeal of solar to homeowners. Switching to solar allows you to lock in the price of electricity for the life of the panels, protecting you from increasing utility prices.
Massachusetts has several incentives that help solar homeowners when installing solar.
Solar installations in Massachusetts pay no sales tax. This can be quite substantial for a $15,000 installations.
Massachusetts also offers a state tax credit, the Residential Renewable Energy Tax Credit, which provides homeowners with an income tax credit of up to $1,000 on their state tax bill.
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.
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.
