The term "solar incentives" refers broadly to financial incentives designed to encourage the adoption and use renewable energy by making installing and using solar panels more affordable. These incentives might include upfront discounts, cash back or credit towards your monthly utility bill. Some incentives are offered by the federal government, some by the Connecticut government and some by your specific utility company, county or municipality. Some solar incentives you might qualify for are:

  • Tax Credits: These credits are dollar-for-dollar reductions (not deductions) in the amount of tax that you owe the federal government.
  • Net Metering: Net metering factors in after your solar panels are up and running. If you've signed a net metering agreement with your Stonington 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 areas, this is a dollar-for-dollar credit, while in other areas you may make back a percentage of the value.
  • Rebates: Solar rebates may be provided by your state or county, or by your local utility company. These rebates are essentially cash back that is applied after you purchase solar panels and before tax credits are calculated.
  • Tax Exemptions: Tax exemptions may come in two forms. First, there is sales tax exemption, applied at the time you purchase your solar panels. The second is property tax exemption, which allows you to ignore the value added by your solar system when calculating property tax for your home.

Federal Solar Incentives

Federal incentives are the type of incentives that you are most likely to have heard of. The solar incentive that you're most familiar with is probably the Federal Solar Investment Tax Credit (ITC), which gives you a credit on your taxes equal to a certain percentage of your solar system's cost.

The ITC applies towards solar systems installed after January 1, 2006, and allows you to deduct from your taxes a percentage of the total cost of solar panels, labor, accessories and equipment. This credit can apply towards solar panels installed on a primary or secondary residence in the United States that you own. The original claim amount was 30% of the total cost, although the amount you can claim may range between 26-30%. There is no maximum claim amount.

To better understand how the ITC could apply to you, speak to your local Stonington solar panel installation expert and ask for more information.

The ITC was both renewed and expanded by the passage of the Inflation Reduction Act in August 2022. It's also now called the Clean Energy Credit. With the new provisions, solar installation projects begun after January 1, 2022, and finished by December 31, 2032, may be eligible for a 30% tax credit. This credit amount will then decrease slightly each year until the end of the current Clean Energy Credit in 2035. Starting in 2023, it will also be easier to obtain credits for energy storage systems with the new act.

State & Local Solar Incentives

In addition to federal solar incentives, there are often also state ones. Rebates, tax credits and more may be available at a more local level. Certain incentives are ongoing, while others are available for a limited time. Solar incentives might be given by the Connecticut government, or by your county or municipality.

Next Steps for Installing Solar in Stonington

Solar energy use nationwide has increased enormously in the past 15 years, in part thanks to the increase in availability of solar incentives. You may get these incentives from the Connecticut government, the federal government or your local utility company. If you're prepared to make the change to solar energy, getting in touch with your local Stonington solar panel installation expert is a great first step.

EcoWatch's Stonington, CT Solar Incentives FAQs

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

Broadly, solar incentives apply to:

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

Specific incentives, including those given out by the Connecticut government or by your county/municipality, could have additional qualifications. Talk to your local Stonington solar installer to find out what incentives your project will qualify for.

My home already has solar panels installed. Are there any incentives that I qualify for?

An excellent idea would be to talk to someone from the company that installed your solar panels – or get in touch with a local Stonington 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 recently increased 30% tax credit under the Inflation Reduction Act. Solar panels installed between 2006 and 2021 may qualify for a tax credit of 26-30%.

What are the environmental benefits of switching to solar?

Solar energy is a renewable energy source — by switching where you get your energy, you help reduce the strain on our planet's resources. Solar panels can also reduce the CO2 emissions from your home by 200 pounds a year, or around 4,000 pounds in 20 years.

I want to trade in my old appliances for ones that are more energy-efficient. Are there any credits I can get?

With the passage of the new Inflation Reduction Act, there are several new financial incentives that are available when you make eco-friendly improvements to your home. More details about these incentives, including information about incentives for purchasing new appliances, can be found here.

Can I use multiple types of renewable energy to power my home?

Yes, you can employ multiple types of renewable energy to power your home, such as a combination of solar and wind power. You can also use both renewable energy sources and a non-renewable backup source of energy. You should discuss your proposed plan with your local Stonington solar installation expert, so that you understand what you'll need and what types of incentives you will or won't qualify for.
