Solar incentives mitigate the cost of installing a solar panel system on your home. This category of financial incentives is designed to encourage more Americans to make the switch to renewable energy. Various kinds of incentives, including cash back, discounts or credit towards your monthly utility bill, may be available to you. Some incentives may be offered by the state of Massachusetts, by your utility company or by county or municipality, while other incentives are federal. You might qualify for any of the following types of solar incentives:

  • Tax Exemptions: These may come in the form of property tax exemptions, which can let you exclude the value of your solar system when paying taxes on your house. You may also qualify for an exemption on sales tax at the time of purchase.
  • Tax Credits: Tax credits reduce, dollar-for-dollar, the amount of income tax you owe the government. These differ from tax deductions.
  • Net Metering: Don't forget to talk to your Groton utility company about signing a net metering contract. This allows you to get a credit towards your utility bill every month for the value of excess energy your solar panels generate. You might receive either a dollar-for-dollar credit or a percentage of the value.
  • Rebates: Rebates, or cash back after a purchase, are normally given before any solar tax credits are calculated. These rebates can be offered by your local utility company, by your county or by your state.
  • Solar Renewable Energy Certificate (SREC): SRECs and other similar performance-based incentives are typically handled by your state government. Once your solar system meets a predetermined threshold (normally a small amount of energy production), you are eligible to receive SRECs that you can then sell to your utility company or other buyers. The money you receive from the sale is usually considered part of your taxable income.

Federal Solar Incentives

When thinking about solar incentives, you probably think of federal incentives first. A federal incentive that most people are likely familiar with is the Federal Solar Investment Tax Credit (ITC). The ITC is a tax credit for a specified percentage of the cost of your solar system.

The ITC can be applied to solar systems installed after January 1, 2006, on a primary or secondary residence in the United States that you own. Originally, the tax credit was for 30% of the total cost – for panels, equipment, labor and accessories – although the percentage may range from 26-30%, depending on when your solar project was undertaken. There is no cap on the amount you can claim.

Contacting your local Groton solar panel installer is the best way to understand how the ITC could apply to your situation.

The Inflation Reduction Act, passed in August 2022, added more provisions to 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 can receive a credit equal to 30% of the total cost. This percentage will decrease annually after 2032 until the Clean Energy Credit ends in 2035. Starting in 2023, the program expansion will also make claiming credit for energy storage systems easier than ever before.

More information about the new Inflation Reduction Act can be found here. To better understand how the new Clean Energy Credit might apply to you, get in touch with your local Groton solar installation expert.

State & Local Solar Incentives

In addition to federal solar incentives, there are often also state ones. Rebates, tax credits and more might be available at a more local level. These incentives might be handled by your county or municipality, or by the Massachusetts government. Certain incentives are ongoing, while others are available for a limited time.

Next Steps for Installing Solar in Groton

You can apply for and receive solar incentives from the federal government and the Massachusetts government, as well as from your local utility company. Growing availability of solar initiatives in the past 15 years has helped increase solar adoption nationwide. Your local Groton solar panel installer can give you more information about which incentives you may qualify for, and get you feeling good about making the change to renewable energy today.

EcoWatch's Groton, MA Solar Incentives FAQs

How do I know if I qualify for solar incentives?

It's best to speak with your local Groton solar installer for a better understanding of which incentives your project may qualify for. In most cases, solar incentives apply to new solar panel systems installed on a property you own (in the U.S.) within a specified date range. Some incentives, like those provided at the level of the Massachusetts government, may have additional requirements.

What are some environmental benefits of installing solar panels on my home?

Solar energy is renewable — by switching where you get your energy, you help reduce the strain on our planet's resources. A solar system can also reduce the CO2 emissions from your home by 200 pounds a year, or roughly 4,000 pounds in 20 years.

Can I apply for 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 applying for, they may apply in a different order. Make sure that you speak with your solar installer or a local tax professional to confirm that you are claiming the correct incentives and getting the most money possible.

Can I use both solar and another type of renewable energy to power my home?

You can power your home with multiple types of renewable energy, or a combination of renewable and non-renewable energy. Make sure you talk through your ideas with your local Groton solar installation expert. They can help you plan your project and also help you understand the various incentives that you will or won't qualify for.

Can I claim incentives for adding solar panels to a vacation home, rental property or commercial property?

Many solar incentives are intended to apply to a property you own that is located within the United States, and most secondary residences fall into this category. Other solar incentives may be available for commercial properties, depending on the details. We recommend speaking with your local solar installer and/or tax professional to better understand what incentives may apply to your specific situation.
