Solar incentives are designed to encourage people to switch to renewable energy by providing incentives meant to lower the financial burden of solar panel installation and use. You may be eligible for different kinds of incentives, such as discounts, cash back or credit towards your monthly utility bill, depending on your situation. Certain incentives come from your specific utility company, county or municipality, some from the Connecticut government and others from the federal government. Categories of solar incentives include:

  • Net Metering: Net metering is an incentive you can get after your solar panels are up and running. If you have a net metering agreement with your Windham utility company, the company will subtract the value of the excess energy produced by your solar system from your utility bill each month. In some locations, this is a dollar-for-dollar credit, while in others you may get refunded a percentage of the value.
  • Rebates: A solar rebate is a partial refund after the purchase of your solar system. These may be offered by your local utility company, your county or your state. The cash back that you get from the rebates is normally applied before tax credits are calculated.
  • Tax Exemptions: Sales tax exemptions are applied at the point of sale for your solar system. Property tax exemptions allow you to exclude the value that your solar panels add when calculating how much property tax you need to pay on your home.
  • Tax Credits: Unlike tax deductions, tax credits reduce, dollar-for-dollar, the amount of income tax that you owe the government.

Federal Solar Incentives

When people think of solar incentives, federal incentives might be the first thing that comes to mind. The Federal Solar Investment Tax Credit, or ITC, is likely the best-known federal solar incentive. The ITC offers a tax credit for a specific percentage of your solar system's cost.

The ITC applies to the value of a solar system installed on your primary or secondary residence in the United States. The solar system has to 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 installation costs (panels, accessories, equipment and labor), although the covered amount has fluctuated slightly 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.

To understand exactly how much the ITC could save you, speak with your local Windham solar panel installation expert.

The Inflation Reduction Act, passed in August 2022, expanded and extended the ITC (as well as retitling it the Clean Energy Credit). The Clean Energy Credit re-raises the credit up to 30% for solar installations undertaken between January 1, 2022, and December 31, 2032. At this point, the credit percentage will see a slight decrease annually until the program expires in 2035. Beginning in 2023, it will also be easier to claim credits for energy storage systems under the new laws.

More information about the new Inflation Reduction Act can be found here. To better understand how the new Clean Energy Credit might apply to you, reach out to your local Windham solar installation company.

State & Local Solar Incentives

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

What are some environmental benefits of installing solar panels on my home?

You can lower your carbon footprint by 200 pounds of CO2 annually by switching to solar panels. This adds up to roughly 4,000 pounds in 20 years. In addition, solar power is a renewable energy source, which means that making the switch lessens the drain on our planet's resources.

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

The new Inflation Reduction Act introduces multiple incentives meant to reward homeowners who make eco-friendly upgrades. Some incentives include tax credits and rebates for installing new electric appliances. You can find more details about these incentives here.

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

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