Solar incentives are intended to make renewable energy usage more affordable through financial incentives for individuals who install solar panels on their homes. 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. You might qualify for any of the following types of solar incentives:

  • Tax Exemptions: Your solar system may qualify for exemptions on both sales and property tax. Sales tax exemptions are effective at the time of purchase. Property tax exemptions let you exclude the added value of the solar panels when you are calculating property taxes on your home.
  • 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, it will subtract the value of the excess energy your solar system produces from your utility bill each month. In some places, this is a dollar-for-dollar credit, while in other places you might receive a refund equivalent to a percentage of the value.
  • Rebates: Your solar installer might help you claim a rebate, or partial refund after purchase, for your solar panels. States or counties will also sometimes offer limited-time rebates. Any rebates you receive will usually be deducted from your total price before any tax credits are calculated.
  • Tax Credits: Unlike tax deductions, tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the government.

Federal Solar Incentives

Federal incentives are the type of incentives that you are most likely to have some knowledge of. It's likely that you've heard of the Federal Solar Investment Tax Credit, or ITC. This incentive is a tax credit that reduces your taxes by a certain percentage of the money you spend on your solar system.

The ITC can be applied to a solar system installed on your primary or secondary residence in the United States. The solar system has to have been installed after January 1, 2006, on a property owned by you for you to claim the credit. Originally, the ITC covered 30% of all installation costs (panels, accessories, labor and equipment), although the total amount has fluctuated over the last few years between 26-30%. The amount you qualify for will depend on when your solar system was installed. There is no cap on the claim amount.

Your local Groton solar panel installation expert can provide you with more information about the ITC and how it may apply to your situation.

In August 2022, the Inflation Reduction Act expanded and extended the ITC, now dubbed the Clean Energy Credit. The Clean Energy Credit re-raises the credit up to 30% for solar systems installed between 2022 and 2032. At this point, the percentage will see a slight decrease annually until the program expires in 2035. The expansion to the program also makes claiming credit for energy storage systems easier than ever before, beginning in 2023.

State & Local Solar Incentives

Some solar incentives are often also offered at the local or state level. As with federal incentives, these could include rebates, tax credits and more. Incentives might be provided by the state of Connecticut, or by your county or municipality. Some incentives may be available for only a limited time, while others are ongoing.
