Solar incentives in Massachusetts

The ITC drops to 26% in 2033 and 22% in 2034.

The federal solar investment tax credit (ITC) is a great way to save money on going solar in Massachusetts. With the ITC, you can get a credit worth 30% of the system’s cost (including equipment, labor and permits) from your federal taxes. For example, in Massachusetts, where a system averages $19,110, residents get an average tax credit of $5,733.

To get the ITC, you need to file federal taxes in the year that your solar panel system becomes operational by filling out Form 5695.

Residential solar incentives in Massachusetts

Massachusetts has many tax breaks, rebates and loan programs for residents who want to install solar panels.

Tax breaks

Massachusetts has several tax breaks to make solar more affordable:

  • State income tax credit: Residents qualify for a 15% credit (up to $1,000) for the cost of solar equipment on their state income taxes. The system must be new and “reasonably expected to remain in operation for at least five years,” according to the Database of State Incentives for Renewables & Efficiency, which tracks renewable energy incentives.
  • Sales tax exemption: There’s a 100% exemption on sales tax for solar equipment for residential power systems. Fill out Massachusetts Tax Form ST-12 and give it to the vendor at the time of purchase.
  • Property tax exemption: Homeowners qualify for a 100% property tax exemption on the value a solar energy system adds to their homes for 20 years. To qualify, you must also have an energy storage system (like a battery).

Some of these incentives require you to live in specific regions of the state, so be sure to check if your town is covered.

  • The Reading Municipal Light Department (RMLD) offers customers a rebate of $1,200 per kilowatt (kW).
  • The town of Wakefield has a rebate of $1.20 per watt for solar systems up to 10 kW.
  • Concord Municipal Light Plant has a rebate program to offset up to $3,125 of your electric bill if you have a solar system.
  • The TMLP solar rebate program in Taunton has a rebate of $1.50 per watt on solar installations (up to $4,500), a $1.20-per-watt rebate (up to 50%) and $300 for solar batteries.
  • Hudson Light & Power offers customers a rebate of $1.20 per watt (up to $7,500) for systems with up to a 25-kW capacity.
  • Shrewsbury Electric & Cable Operations (SELCO) offers a solar rebate of 10 cents per watt up to $1,000.
  • The Ipswich Electric Light Department offers rebates of 30 cents per watt (up to $3,000) on solar systems.
  • The Solar Massachusetts Renewable Target (SMART) program provides up to 17 cents per kilowatt-hour (kWh) for electricity statewide.

Loan programs

Need financing? Several solar loans are offered in Massachusetts:

  • Holyoke Gas & Electric’s Residential Energy Conservation Program (RECP) has solar loans of up to $10,000 for citizens of Holyoke.
  • The Mass Save program has zero-interest loans of up to $25,000 for Liberty Utilities, Cape Light Compact, National Grid, Eversource and Unitil customers.
  • The Property-Assessed Clean Energy (PACE) program helps you finance solar with a fixed-rate loan paid back through a fee added to your property taxes.

What to know about net metering in Massachusetts

Net metering is the process of selling excess electricity made by your solar panels to the power grid. While many people store their extra power in solar batteries, some opt for net metering to help offset their electric bill. As part of the state’s net metering rules, new solar customers get net metering credits equal to 60% of their net excess kilowatt-hours.

It’s a great deal for residents, but there are occasional hiccups, as Peter in Weymouth found out.

“My system is doing great,” Peter said. “But I was still getting full electric bills from my electric provider.” His solar company arranged for an electrician to change his electric meter over to a net metering unit. “But the meter that they put in was another standard meter. So, I lost over two months’ worth of solar energy.”

He had to work with the service provider to get it back. “The electric company came out and changed my meter again and put on the correct meter. So going forward, it should work,” he said.

You can also take advantage of the solar renewable energy certificate (SREC) program. For example, Ronald in Groton installed 32 solar panels on his roof in Lincoln. “They were paid off in four years, and since then I have received an average of $2,400 per year in SREC payments,” he said.
