The phrase "solar incentives" includes 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. The incentives can include cash back, upfront discounts or monthly credits towards your utility bill. Some incentives are given 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:

  • Net Metering: Make sure you talk to your Stonington utility company about signing a net metering agreement. This allows you to get a credit towards your monthly utility bill 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.
  • Tax Credits: Different from tax deductions, tax credits reduce, dollar-for-dollar, the amount of income tax that you owe the government.
  • Tax Exemptions: Sales tax exemptions are applied at the point of sale for your solar system. Property tax exemptions let you exclude the value that your solar panels add when you calculate the amount of property tax you need to pay on your home.
  • Rebates: A solar rebate is a partial refund given after you've purchased your solar system. Rebates could be offered by your local utility company, your county or your state. The discount that rebates offer is normally applied to the price of solar panels before tax credits are calculated.

Federal Solar Incentives

When you think about solar incentives, you likely think of federal incentives first. You've likely heard of the Federal Solar Investment Tax Credit, or ITC. This is a tax credit that reduces your taxes by a specified percentage of the money you spend on your solar system.

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 system must have been installed after January 1, 2006 on a property owned by you for you to be eligible for the credit. The ITC originally paid out 30% of all system installation costs (panels, labor, accessories and equipment), although this amount has fluctuated slightly over the 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.

Speaking with your local Stonington solar panel installer is the best way to learn more about how the ITC could apply to you.

In August 2022, the ITC (now titled the Clean Energy Credit) was expanded and extended by the passage of the Inflation Reduction Act. For solar system installations that begin after January 1, 2022 and are completed by the end of 2032, homeowners can apply for a credit equal to 30% of the total cost. This percentage will decrease annually after 2032 until the Clean Energy Credit expires in 2035. The program expansion also makes credits for energy storage systems even easier to claim, starting in 2023.

More information about the new Inflation Reduction Act can be found here. The best way to fully understand how the new Clean Energy Credit applies to you is to get in touch with your local Stonington solar panel company.

State & Local Solar Incentives

Federal solar incentives are not your only option; rebates, tax credits and more may be offered at the state and local level. Certain incentives are offered for only a limited time, while others are ongoing. Your local solar incentives could come from your county or municipality, or from the Connecticut government.

Next Steps for Installing Solar in Stonington

EcoWatch's Stonington, CT Solar Incentives FAQs

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

While we recommend talking to your local solar installer and/or tax professional to fully understand what solar incentives apply to you, many incentives will apply to a second home, provided that it is in the United States and owned by you. There may be additional incentives available specifically for commercial properties, depending on the details.

How much can I save annually on my electric bill if I install solar panels on my Stonington home?

Typically, Stonington homeowners who install solar panels save around $1,200.60 per year, or around $22,811.47 over 20 years after making the switch.

When does the federal solar tax credit end?

The Clean Energy Credit (formerly called the federal solar tax credit, or ITC), currently ends on January 1, 2035. Currently set at 30%, the credit will drop to 26% in 2033 and to 22% in 2034.

Can I receive incentives both towards the initial cost of solar panels, and later as reimbursement?

Yes, you can claim both tax credits and rebates towards the cost of solar panels. Depending on precisely which incentives you are eligible for, they may apply in a different order. Make sure that you speak with your solar installer or a local tax professional to verify that you are claiming the correct incentives and getting the most money you can.

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

You can power your home with multiple types of renewable energy, or a combination of renewable and non-renewable energy. Be sure to talk through your plan with your local Stonington solar installer. They can help you with the plan for your project and also help you understand the various incentives that you may or may not qualify for.
