Solar incentives mitigate the cost of installing a solar panel system on your home. These financial incentives are in place to encourage more Americans to switch their home over to renewable energy. Incentives could include things like discounts, cash back or credit towards your monthly utility bill. Some incentives are offered federally, while others are provided by the Massachusetts government or by your utility company, county or municipality. Categories of solar incentives include:

  • Rebates: Your solar installer might help you claim a rebate, or partial refund of your purchase, for your solar panels. States or counties will also sometimes offer limited-time rebates. Any rebates you receive will usually come off the total price before tax credits are calculated.
  • Net Metering: Net metering becomes relevant once your solar system is up and running. If you've signed a net metering agreement with your Groton utility company, they will subtract the value of the excess energy produced by your solar system from your utility bill each month. In some locations, this credit is dollar-for-dollar, while in others you may receive a refund equivalent to a percentage of the value.
  • Solar Renewable Energy Certificate (SREC): SRECs can be sold to your utility company (or other buyers) for cash that typically becomes part of your taxable income. Generally, a certain (small) threshold of energy production must be met before your solar system can earn SRECs or other performance-based incentives. SRECs and similar incentives are normally handled by your state government.
  • Tax Credits: Tax credits are dollar-for-dollar reductions that lower the amount of income tax you owe the government. (A tax credit is different from a tax deduction.)
  • Tax Exemptions: Sales tax exemptions are applied at the time of purchase for your solar panels. Property tax exemptions allow you to exclude the added value of your solar system when calculating how much property tax you need to pay on your home.

Federal Solar Incentives

When someone says "solar incentives," you likely think of federal incentives first. The Federal Solar Investment Tax Credit, or ITC, is the best-known federal solar incentive. The ITC provides you with a tax credit for a specific percentage of your solar system's cost.

The ITC covers solar systems installed after January 1, 2006 and lets you deduct from your taxes a percentage of the total cost of solar panels, equipment, accessories and labor. This credit can apply towards solar panels installed on a primary or secondary residence that you own in the United States. Originally, you could claim 30% of the total cost, although the amount you can claim may range between 26-30%. There is no maximum claim amount.

Have questions about how the ITC applies to your specific situation? Contact your local Groton solar panel installer to get more information.

The ITC has been renewed and expanded following the passage of the Inflation Reduction Act in August 2022. It's also now called the Clean Energy Credit. Under the new program, solar installation projects begun after January 1, 2022 and finished by December 31, 2032 may be eligible for a 30% tax credit. This credit amount will then decrease slightly each year until the current Clean Energy Credit expires in 2035. Starting in 2023, the expansion will also make credits for energy storage systems even easier to claim.

More information about the new Inflation Reduction Act can be found here. To better understand how the new Clean Energy Credit applies to you, talk to your local Groton solar installation company.

State & Local Solar Incentives

Tax credits, rebates and more might be claimed at multiple levels. Along with federal solar incentives, there are often state and local ones as well. Certain incentives are offered for only a limited time, while others are ongoing. Your local incentives might come from your county or municipality, or from the Massachusetts government.

EcoWatch's Groton, MA Solar Incentives FAQs

Can I get any financial incentives when I add solar panels to a vacation home, rental property or commercial property?

While we recommend getting in touch with your local solar installer and/or tax professional to best understand what solar incentives apply to you, many incentives apply to a second home, as long as it is in the United States and owned by you. There may be other incentives available for commercial properties specifically, depending on the specifics.

If I installed solar panels on my house a few years ago, can I still claim incentives?

If your solar system was installed after January 1, 2022, you may qualify for the recently increased 30% tax credit under the Inflation Reduction Act. If you installed your system between 2006 and 2021, you might qualify for a tax credit between 26% and 30%, depending on the year it was installed. Talking to the company that installed your system, or any local Groton solar installer, can help you understand what incentives you might want to apply for.

How much will solar panels save me annually on my electric bill in Groton?

Generally, Groton homeowners who install solar panels save about $1,159.57 per year, or about $22,031.82 over 20 years after making the switch.

If I trade in my appliances for ones that can use solar energy, are there credits that I can claim?

The recently passed Inflation Reduction Act includes provisions for a number of incentives that reward homeowners for making eco-friendly upgrades. Some incentives include rebates and tax credits for installing new electric appliances. You can find more details about these incentives here.

Can I receive incentives both towards the initial cost of solar panels, and later as reimbursement?

Yes, you can receive both tax credits and rebates towards the cost of your solar panels. Depending on which incentives you are claiming, they may apply in a different order. Be sure to talk to your solar installer or a local tax professional to verify that you are claiming the correct incentives and getting the most money you can.
