Massachusetts Solar Incentives

Massachusetts Solar Incentives, Tax Credits, and Rebates

There are several incentives in Massachusetts that make investing in solar and renewable energy cost-effective.

Massachusetts and the Federal solar tax credit

Massachusetts residents can claim the federal solar tax credit. Currently, the federal solar tax credit is 26% of the total cost of your new solar panel system. This includes the installation labor, equipment, and permitting costs.

For Example, if your solar panel system costs $25,000, your tax credit would be $25,000 x 26% = $6,500.

You can learn more about the federal solar tax credit here. 

Net metering in Massachusetts

Net metering is a billing mechanism that allows your solar panels to give you a credit for putting electricity into the grid. When your solar panels produce more electricity than you can use, the leftover energy is back on to the grid and you get credit for the energy you produced.

Massachusetts residents are able to receive bill credits for any excess energy they generate. This is a huge financial incentive since it means you receive financial benefits from every bit of energy you generate. You can find more information on Mass.gov
