Federal Residential Renewable Energy Tax Credit
Solar incentives are designed to encourage homeowners to switch to renewable energy by providing incentives meant to lower the financial burden of solar panel installation and use. Incentives could include things like discounts, cash back or monthly utility bill credits. Some incentives are handled federally, while others are offered by the state of Massachusetts or by your utility company, county or municipality. You might qualify for any of the following types of solar incentives:
- Tax Exemptions: Sales tax exemptions are effective at the time of purchase for your solar system. Property tax exemptions let you ignore the added value of your solar system when you're calculating how much property tax you need to pay.
- Net Metering: Net metering is an incentive you can get once your solar panels are up and running. If you've signed a net metering agreement with your Groton utility company, the company will subtract the value of the excess energy your solar system produces from your utility bill each month. In some places, this credit is dollar-for-dollar, while in other areas you might be refunded a percentage of the value.
- Tax Credits: Unlike tax deductions, tax credits reduce, dollar-for-dollar, the amount of income tax that you owe the government.
- Solar Renewable Energy Certificate (SREC): SRECs and other performance-based incentives may be available to you if the solar system on your home produces more than a specified (usually small) amount of electricity. Performance-based incentives are typically handled at the state level. You can sell the SRECs you receive to your utility company or other buyers, and the money you receive in return is normally considered part of your taxable income.
- Rebates: Rebates, or cash back after a purchase, are normally given prior to any solar tax credits being calculated. Rebates may be offered by your local utility company, by your state or by your county.
Federal Solar Incentives
Federal incentives are the type of incentives that you are most likely to have some knowledge of. The Federal Solar Investment Tax Credit, or ITC, is likely the best-known federal solar incentive. The ITC offers a tax credit for a set percentage of your solar system's cost.
The ITC can be applied to solar panels installed after January 1, 2006 on a primary or secondary residence that you own in the United States. The credit initially covered 30% of the total cost — for panels, equipment, labor and accessories — although that amount may range from 26-30%, depending on when your solar project was undertaken. There is no cap on the claim amount.
Have questions about how the ITC applies to your specific situation? Get in touch with your local Groton solar panel installer to get more information.
The Inflation Reduction Act, passed in August 2022, expanded and extended the ITC (as well as renaming it to the Clean Energy Credit). For solar system installations that begin after January 1, 2022 and are completed by the end of 2032, homeowners may be eligible for a credit equal to 30% of the total cost. After 2033, the percentage will decrease annually until the Clean Energy Credit ends in 2035. The expansion also makes claiming credit for energy storage systems easier than ever before, beginning in 2023.
More information about the new Inflation Reduction Act can be found here. Your local Groton solar panel installer can answer any questions you have and explain how the new Clean Energy Credit will apply to you.
State & Local Solar Incentives
In addition to federal solar incentives, there are often also state ones. Tax credits, rebates and more can be offered at a more local level. Certain incentives are ongoing, while others are offered for only a limited time. Your local incentives might come from the Massachusetts government, or from your specific county or municipality.

EcoWatch's Groton, MA Solar Incentives FAQs
What if I want to add a solar system to a rental property, vacation home or commercial property? Will I still qualify for incentives?
While we recommend speaking with your local solar installer and/or tax professional to better understand what solar incentives apply to you, many incentives can be claimed on a second home, so long as that home is in the United States and owned by you. There may be other incentives available for commercial properties specifically, depending on the specifics.
How do I know if I qualify for certain solar incentives?
It's a smart idea to get in touch with your local Groton solar installer to get an understanding of which incentives your project will qualify for. In most cases, solar incentives apply to new solar panel systems installed on property you own (in the U.S.) within a specified date range. Some incentives, such as those provided by the Massachusetts government, might have additional requirements.
How much can I save annually on my electric bill if I install solar panels on my Groton home?
After adding solar panels to your house in Groton, you can anticipate savings of about $1,159.57 per year, or about $22,031.82 over 20 years.
When does the federal solar tax credit end?
The federal solar tax credit, formerly called the ITC and now titled the Clean Energy Credit, is set to end January 1, 2035. The current 30% credit will end in 2032, replaced by a 26% credit in 2033 and a 22% credit in 2034.
If I switch my appliances out for ones that use solar energy, are there credits 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.
