The phrase "solar incentives" refers broadly to financial incentives implemented by the government and by solar companies to encourage people to use renewable energy by making solar panels more affordable. Solar incentives may include upfront discounts, cash back or monthly credits towards your utility bill. Some incentives are handled by the federal government, some by the state of Connecticut and some by your specific utility company, county or municipality. Some solar incentives you might qualify for are:

  • Tax Exemptions: These could come in the form of property tax exemptions, which can let you ignore the value added by your solar panels when paying property tax on your home. You could also look for exemptions on sales tax at the time of purchase.
  • Net Metering: Be sure to talk to your Groton utility company about signing a net metering contract. This will allow you to get a credit towards your monthly utility bill for the value of excess energy your solar panels generate. You could receive either a dollar-for-dollar credit or a percentage of the value.
  • Rebates: A rebate is a partial refund given after you've purchased your solar panels. These might be offered by your local utility company, your county or your state. The discount that rebates offer is normally applied to the price of solar panels before tax credits are calculated.
  • Tax Credits: Tax credits lower, dollar-for-dollar, how much income tax you owe the government. These are different from tax deductions.

Federal Solar Incentives

Federal incentives are the type of incentives that you are most likely to have heard of. One of the incentives that most people are likely to be familiar with is the Federal Solar Investment Tax Credit (ITC). The ITC is a tax credit for a given percentage of your solar system's cost.

The ITC applies to a solar system installed on your primary or secondary residence in the United States. The solar panels must have been installed on a property you own after January 1, 2006, for you to claim the credit. The ITC originally paid out 30% of all installation costs (panels, accessories, labor and equipment), although the covered amount has fluctuated over the years between 26-30%. The installation date of your solar system will determine what percentage you are eligible for. There is no cap on the amount you can claim.

Contacting your local Groton solar panel installer is the best way to learn more about how the ITC may apply to your situation.

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. The Clean Energy Credit has increased the current credit up to 30% for solar systems installed between 2022 and 2032. After 2032, the percentage will see a slight decrease annually until the program expires in 2035. The expansion to the program also makes it easier to get credit for energy storage systems, beginning in 2023.

Rebates, tax credits and more can be claimed at multiple levels. In addition to federal solar incentives, there are often state and local ones as well. These incentives might be provided by your county or municipality, or by the Connecticut government. Some incentives may be available for a limited time, while others are ongoing.
