SMART Program

The Solar Massachusetts Renewable Target (SMART) program replaced the previous solar renewable energy credit (SREC) program. Through the SMART program, your utility pays you a flat base-rate per kilowatt hour (kWh) of solar electricity your system produces for 10 years. 

In return, the your utility gets ownership of all of your SRECs. The base rate you recieve depends on your utility and when you apply to the program. Right now, Boston residents serviced by Eversource would recieve an additioanl $0.165 per kWh of solar produced. 

Massachusetts state tax credit

Massachusetts offers a state solar tax credit. This means you can earn an extra $1,000 to put towards your taxes - on top of the federal solar tax credit.


The 30% federal solar tax credit explained

The most significant incentive to install solar panels for homes and and businesses is the federal tax credit. Right now, the federal tax credit is equal to 30% of the total cost to install a solar system. The amount of the tax credit is then deducted from your federal taxes. You can claim the credit over several years if the amount you owe in taxes is less than the amount of your tax credit. You can only take advantage of the federal tax credit if you pay federal income taxes. At the end of 2032, the amount of the tax credit will fall to 26%. Even though there is no rush to get the maximum tax credit value, you don’t want to wait when it comes to a financial investment like installing solar. The best time to go solar is now.

How much will solar panels on my home save me?

The answer to this question depends on your electricity usage. Generally speaking, the higher your power usage, the greater your potential savings are from installing solar.

The average monthly electricity usage in Massachusetts is about 599 kWh per month. However, you are most likely using a lot more than this since this average includes small apartments and condos.

The Boston solar panel savings calculator uses our database of electric rates from local utilities to convert your monthly power bill into how much electricity your home uses. From there, the calculator can work out how many solar panels you need to offset your power usage, how much a solar system will cost based on prices of local solar companies, and the amount of money you will save on your electric bill.
