Solar incentives mitigate the cost of installing a solar panel system on your home. These financial incentives are intended to encourage more homeowners to make the switch to renewable energy. Solar incentives might include cash back, upfront discounts or monthly credits towards your utility bill. Some incentives are offered 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 panel system could qualify for both sales tax and property tax exemptions. Sales tax exemptions come into effect at the time of purchase. Property tax exemptions allow you to exclude the value that solar panels add when you are calculating property taxes on your house.
  • Tax Credits: Different from tax deductions, tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the federal government.
  • Rebates: Rebates, or cash back after a purchase, are normally applied before any solar tax credits are calculated. Rebates may be given by your local utility company, by your state or by your county.
  • Net Metering: Net metering factors in after your solar system is up and running. If you've signed a net metering agreement with your Danbury utility company, they will subtract the value of the excess energy your solar system produces from your monthly utility bill. In some areas, this is a dollar-for-dollar credit, while in other places you may receive a refund equivalent to a percentage of the value.

Federal Solar Incentives

When people think of solar incentives, federal incentives may be the first thing that comes to mind. The Federal Solar Investment Tax Credit, or ITC, is likely the most commonly known federal solar incentive. The ITC provides a tax credit for a set percentage of the cost of your solar system.

The ITC applies to solar systems installed after January 1, 2006, on a primary or secondary residence in the United States that you own. The credit initially covered 30% of the total cost – for panels, accessories, equipment and labor – although that amount may range from 26-30%, depending on the installation date of your solar system. There is no cap on the claim amount.

To best understand how the ITC might apply to your situation, call your local Danbury solar panel installation expert and ask for more information.

In August 2022, the Inflation Reduction Act expanded and extended the ITC, now titled the Clean Energy Credit. For solar system installations that begin after January 1, 2022, and are completed by the end of 2032, homeowners can apply for a credit for 30% of the total cost. The percentage will then decrease annually until the Clean Energy Credit expires in 2035. Starting in 2023, it will also be easier to get credits for energy storage systems with the new act.

State & Local Solar Incentives

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