Solar incentives mitigate the cost of installing solar panels on your home. These financial incentives are intended to encourage more Americans to convert their home partially or fully to renewable energy. Incentives might include things like discounts, cash back or monthly utility bill credits. Some incentives are handled federally, while others are handled by the Connecticut government or your utility company, county or municipality. Some solar incentives you might qualify for are:

  • Tax Credits: Tax credits are dollar-for-dollar reductions (not deductions) in the amount of tax that you owe the government.
  • Net Metering: Don't forget to talk to your Groton utility company about signing a net metering contract. This allows you to receive credit towards your utility bill every month for the value of excess energy generated by your solar panels. You might receive either a dollar-for-dollar credit or a percentage of the value.
  • Tax Exemptions: Your solar panels may qualify for exemptions on both sales and property tax. Sales tax exemptions are applied at the time of purchase. Property tax exemptions allow you to ignore the value added by your solar panels when you are calculating property taxes on your home.
  • Rebates: Rebates, or cash back after a purchase, are typically applied prior to any solar tax credits being calculated. Rebates might be given 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. An incentive many people are probably familiar with is the Federal Solar Investment Tax Credit (ITC). This incentive is a tax credit for a certain percentage of the cost of your solar system.

The ITC covers solar systems installed after January 1, 2006 and under this program you can deduct from your taxes a percentage of the total cost of solar panels, labor, equipment and accessories. You can claim this credit for a solar panel system installed on a primary or secondary residence that you own in the United States. The original amount you could claim was 30% of the total cost, although certain projects may qualify for only 26%, depending on the details. There is no maximum amount you can claim.

Your local Groton solar panel installer can offer more information about the ITC and how it might apply to your situation.

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. The percentage will then decrease annually until the Clean Energy Credit expires in 2035. Starting in 2023, the expansion to the program will also make credits for energy storage systems even easier to claim.

More information about the new Inflation Reduction Act can be found here. The best way to fully understand how the new Clean Energy Credit will apply to you is to reach out to your local Groton solar panel installers with your questions.

State & Local Solar Incentives

There are more than just federal solar incentives; rebates, tax credits and more might also be offered at the local or state level. These incentives might be given out by your county or municipality, or by the Connecticut government. Some are ongoing, while others are available for a limited time.

Next Steps for Installing Solar in Groton

You can qualify for solar incentives from the Connecticut government and the federal government, as well as from your local utility company. The increased availability of solar initiatives in the past 15 years has helped increase nationwide solar energy use enormously. We suggest talking to your local Groton solar installer to learn more about these incentives and to be sure that you're getting the largest number possible for your solar system.

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

You can decrease your carbon footprint by 200 pounds of CO2 annually by switching to solar panels. This adds up to roughly 4,000 pounds in 20 years. Solar is also a renewable energy source, which means that making the switch reduces the drain on our planet's resources.

How long until the federal solar tax credit ends?

The Clean Energy Credit (formerly called the federal solar tax credit, or the ITC), is scheduled to end on January 1, 2035. Currently set at 30%, the credit will drop to 26% in 2033 and to 22% in 2034.

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