Solar incentives are designed to make renewable energy usage more affordable through financial incentives for individuals who install solar panels on their homes. Solar incentives can include cash back, upfront discounts or monthly credits towards your utility bill. Some incentives are provided 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 both sales tax and property tax exemptions. Sales tax exemptions are applied at the time of purchase. Property tax exemptions allow you to exclude the value that solar panels add when 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've signed a net metering agreement with your Windham utility company, they will subtract the value of the excess energy produced by your solar system from your monthly utility bill. In some places, this credit is dollar-for-dollar, while in others you might receive a refund equivalent to a percentage of the value.
  • Tax Credits: Tax credits decrease, dollar-for-dollar, the total amount of tax you owe the federal government. These differ from tax deductions.
  • Rebates: Solar rebates may be offered by your local utility company, or by your state or county. These rebates are essentially cash back that is applied after you pay for solar panels and before tax credits are calculated.

Federal Solar Incentives

Federal incentives are the kind of incentives that you are most likely to have heard of. The Federal Solar Investment Tax Credit, or ITC, is probably the best-known federal solar incentive. The ITC provides you with a tax credit for a specific percentage of the cost of your solar system.

The ITC applies to a solar system installed on your primary or secondary residence in the United States. The solar panels have to have been installed after January 1, 2006 on a property you own for you to claim the credit. Originally, the ITC covered 30% of all installation costs (panels, equipment, labor and accessories), although the total amount has fluctuated over the last few 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.

Have questions about how the ITC applies to your specific situation? Contact your local Windham solar panel installation expert to get 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 lasts until 2035. Your solar installation project undertaken between 2022 and 2032 may qualify for a 30% tax credit. The amount will be decreased slightly each year until the end of the current program. Starting in 2023, it will also be easier to get credits for energy storage systems with the new act.

State & Local Solar Incentives

Not all solar incentives are federal; rebates, tax credits and more may be offered at the state and local level. Incentives might be handled by your county or municipality, or by the state of Connecticut. Some incentives might only be available for a limited time, while others are ongoing.

Next Steps for Installing Solar in Windham

You can qualify for solar incentives from the federal government and the Connecticut government, as well as from your local utility company. The increased availability of solar initiatives in the past 15 years has helped increase nationwide solar energy use enormously. Your local Windham solar panel installation company can give you more information about which incentives you should apply for, and get you started on the path to switching to renewable energy today.

EcoWatch's Windham, CT Solar Incentives FAQs

What if I add solar panels to a rental property, vacation home or commercial property? Do I still qualify for incentives?

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

My home already has solar panels installed. Do I qualify for any incentives?

You should plan to talk to the company that installed your solar panels — or get in touch with a local Windham solar installer — to better understand which incentives you might qualify for. If your system was installed after January 1, 2022, you likely qualify for the recently increased 30% tax credit under the Inflation Reduction Act. Systems installed between 2006 and 2021 may qualify for a tax credit of 26-30%.

How much can I save annually on my electric bill if I add solar panels to my house in Windham?

On average, Windham homeowners who install solar panels save about $1,175.84 per year, or about $22,341.04 over 20 years after making the switch.
