Solar incentives encourage homeowners to switch to renewable energy by offering financial incentives that lower the burden of solar panel installation and use. Different types of incentives, like discounts, cash back or credit towards your monthly utility bill, might be available to you. Certain incentives may be offered by the state of Connecticut, by your utility company or by county or municipality, while other incentives are federal. Some broad categories of solar incentives include:

  • 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 house.
  • Net Metering: Net metering is an incentive you can get once your solar panels are up and running. If you have in place a net metering agreement with your Fairfield 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 may receive a refund equivalent to a percentage of the value.
  • Tax Credits: Tax credits are dollar-for-dollar reductions that lower the amount of income tax you owe the government. (A tax credit is different from a tax deduction.)
  • Rebates: Rebates, or partial refunds after a purchase, are typically applied prior to any solar tax credits being calculated. Solar rebates may be given by your local utility company, by your state or by your county.

Federal Solar Incentives

When someone says "solar incentives," you probably think of federal incentives first. A federal incentive that most people are probably familiar with is the Federal Solar Investment Tax Credit (ITC). The ITC is a tax credit for a certain percentage of your solar system's cost.

The ITC applies to the total cost of solar system installation, including the panels themselves as well as equipment, accessories and labor. You can claim this credit for panels installed after January 1, 2006 on a primary or secondary residence that you own and that is located in the United States. Originally set at 30% of total costs, the credit has fluctuated over time, and you may qualify for different amounts depending on when your project was completed. There is no maximum amount you can claim.

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

In August 2022, the Inflation Reduction Act laid out new provisions for the ITC, now referred to as 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. This percentage will decrease annually after 2032 until the Clean Energy Credit ends in 2035. Starting in 2023, the expansion to the program will also make credits for energy storage systems even easier to claim.

State & Local Solar Incentives

Federal solar incentives are not your only option; tax credits, rebates and more are often offered at the state and local level. Some incentives are ongoing, while others may only be available for a limited time. Solar incentives might be offered by the Connecticut government, or by your county or municipality.

EcoWatch's Fairfield, CT Solar Incentives FAQs

Can I receive any incentives when I add solar panels to a vacation home, rental property or commercial property?

Many solar incentives apply to a property located within the United States that you own; most secondary residences will fall under this distinction. Other solar incentives may be available for commercial properties, depending on the specifics. We recommend speaking with your local solar installer and/or tax professional to best understand what incentives apply to your specific situation.

How do I know if I qualify for certain solar incentives?

In most cases, solar incentives apply to:

  1. a new solar system
  2. installed on property that you own
  3. within the U.S.
  4. between the dates specified by a particular incentive.

Specific incentives, including ones handled by the Connecticut government or by your county/municipality, sometimes have additional qualifications. Talk to your local Fairfield solar installer to discover what incentives your project may qualify for.

If I already have solar panels, can I still claim incentives?

An excellent idea would be to talk to a representative from the company that installed your solar system — or get in touch with a local Fairfield solar installer — to learn about which incentives you might qualify for. If your system was installed after January 1, 2022, you likely qualify for the newly increased 30% tax credit under the Inflation Reduction Act. Systems installed between 2006 and 2021 may qualify for a tax credit of 26-30%.

Speak to your solar installer or a local tax professional to make sure you are claiming all of the incentives you qualify for and applying them in the correct order.
