Massachusetts may not be considered a particularly sunny state, but it’s a surprisingly great place to transition to solar energy. According to the Solar Energy Industries Association (SEIA), the Bay State has invested $9.6 billion in renewable energy, and over 20% of its electricity comes from solar power.

Massachusetts offers homeowners multiple ways to save money when switching to solar energy. In researching the industry’s best solar companies, we’ve analyzed solar rebates and incentives nationwide. See which incentives Massachusetts residents qualify for below.

Massachusetts Solar Incentives, Tax Credits, and Rebates

Taking advantage of Massachusettsincentive programs can save you thousands of dollars on solar system costs. Learn about each available program below.

Solar Massachusetts Renewable Target (SMART)

Under the SMART program, Massachusetts pays Eversource, National Grid, and Unitil customers a fixed rate per kilowatt hour (kWh) of solar energy produced for 10 years. The rate ranges from 19 to 31 cents per kWh for systems under 25 kilowatts (kW), depending on your location and utility. Most residential systems are under 10 kW.

Additional resources:

Property Tax Exemption

Installing solar panels increases home value. This typically raises the property taxes you owe, but Massachusetts makes an exception for solar installations. However, this exemption is only in place for 20 years from the time of installation. After 20 years, you must pay property tax on the full property value.

Additional resources:

Sales Tax Exemption

Massachusetts waives its 6.25% state sales tax for solar equipment. The solar company you buy your system from automatically won’t apply this tax. For the average residential solar panel system, that’s around $1,000 you don’t have to spend.

Additional resources:


Net-metering is a billing program that helps system owners earn money while saving on electric bills. You can sell any excess energy your system generates to your local utility company through a net-metering program in exchange for a payout or electric bill credits.

Utility companies Eversource and National Grid have Massachusetts’ top net-metering programs.

Federal Tax Credit

One of the most lucrative ways to save on solar panels is the federal solar investment tax credit (ITC), also referred to as the residential clean energy credit. This nationwide program originated with the Energy Policy Act of 2005. It allows you to claim a percentage of your solar energy system costs on your federal taxes the year you install it. This percentage has changed throughout the years but will stay at 30% until 2033.

The average home solar system in Massachusetts costs around $17,800.* The federal tax credit allows you to claim $5,300 of this price on your taxes for a total cost of $12,500. Only homeowners who purchase their system in cash or take out a loan qualify. Leasing and power purchase agreement (PPA) customers are ineligible because they don’t legally own their systems.

The ITC is a onetime credit, but you can carry it over to the next tax year if you can’t use it all when you file. For example, if you owe $3,000 in taxes the year you install and get a $4,000 tax credit, you’ll owe $0 on that year’s federal tax bill and reduce the next year’s by the leftover $1,000.

You can claim the solar tax credit when you file your yearly federal tax return. Let your accountant know in advance. You must fill out IRS Form 5695 if you manage your own taxes.
