The phrase "solar incentives" covers a wide range of financial incentives designed to make installing and using solar panels more affordable. This is done to encourage people to switch to renewable energy. Solar incentives may include upfront discounts, cash back or credit towards your monthly utility bill. Some incentives are provided by the federal government, some by the state of Connecticut and some by your utility company, county or municipality. You might qualify for any of the following types of solar incentives:

  • Net Metering: Be sure to speak to your Windham utility company about signing a net metering agreement. This will allow 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.
  • Rebates: Solar companies may help you claim a rebate, or partial refund after purchase, for your solar panels. States or counties will also sometimes offer limited-time rebates. If you receive a rebate, that amount will usually come off the total price before tax credits are calculated.
  • Tax Exemptions: These may come in the form of property tax exemptions, which would allow you to ignore the value of your solar system when calculating the taxes you pay on your house. They may also include exemptions on sales tax at the time of purchase.
  • Tax Credits: Tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the federal government. (A tax credit is different from a tax deduction.)

Federal Solar Incentives

When thinking about solar incentives, you likely think of federal incentives first. The Federal Solar Investment Tax Credit, or ITC, is likely the best-known federal solar incentive. The ITC provides a tax credit for a predetermined percentage of your solar system's cost.

The ITC can be credited towards the value of 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. Initially, the ITC applied to 30% of all system costs (panels, accessories, equipment and labor), although the 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.

To more fully understand how the ITC will apply to your situation, get in touch with your local Windham solar panel installation expert and ask for more information.

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 runs until 2035. Any solar installation project that is completed between January 1, 2022, and December 31, 2032, may qualify for a 30% tax credit; the amount will then decrease slightly on a yearly basis until the end of the current program. Starting in 2023, the expansion to the program will also make credits for energy storage systems even easier to claim.

State & Local Solar Incentives

Some solar incentives are often also provided by state and local governments. Like with federal incentives, these might include rebates, tax credits and more. These incentives — which may be provided by your county or municipality, or by the state of Connecticut — could be offered on an ongoing basis, or for only a limited time.

Next Steps for Installing Solar in Windham

You can apply for and receive solar incentives from the federal government and the Connecticut government, as well as from your local utility company. This increase in availability of solar initiatives over the last 15 years has helped greatly increase nationwide adoption of solar energy. If you're prepared to switch over to solar energy, getting in touch with your local Windham solar panel installation expert is a great first step.

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

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

While we recommend getting in touch with your local solar installer and/or tax professional to best understand what solar incentives apply to you, many incentives apply to a second home, so long as that home is in the United States and owned by you. There may be other incentives available specifically for commercial properties, depending on the specifics.
