The phrase "solar incentives" refers broadly to financial incentives put in place by solar companies and the government to encourage people to use renewable energy by making the installation and use of solar panels more affordable. You may be eligible for different kinds of incentives, such as cash back, discounts or credit towards your monthly utility bill, depending on your situation. Some incentives come from your specific utility company, county or municipality, some from the state of Connecticut and others from the federal government. Types of solar incentives might include:

  • Net Metering: Net metering is an incentive you can get after your solar panels are up and running. If you've signed a net metering agreement with your Killingly utility company, they will subtract the value of the excess energy produced by your solar system from your monthly utility bill. In some areas, this is a dollar-for-dollar credit, while in others you might be refunded a percentage of the value.
  • Tax Exemptions: Sales tax exemptions are effective at the point of sale for your solar system. Property tax exemptions allow you to exclude the added value of your solar system when you calculate how much property tax you need to pay.
  • Tax Credits: Tax credits are dollar-for-dollar reductions that lower the amount of income tax you owe the federal government. (A tax credit is different from a tax deduction.)
  • Rebates: Some solar companies will help you claim a rebate, or partial refund after purchase, for your solar panels. States or counties will also offer limited-time rebates at various times. Any rebates you receive will usually come off the total price before tax credits are calculated.

Federal Solar Incentives

Federal incentives are the kind of incentives that you are most likely to have some knowledge of. You've likely heard of the Federal Solar Investment Tax Credit, or ITC. The ITC is a tax credit that reduces your taxes by a predetermined percentage of the money you spend on your solar system.

The ITC applies to solar panels installed after January 1, 2006 on a primary or secondary residence in the United States that you own. Originally, the tax credit was for 30% of the total cost — for panels, accessories, labor and equipment — although it may range from 26-30%, depending on when your solar system was installed. There is no cap on the claim amount.

To better understand how the ITC may apply to your situation, speak to your local Killingly solar panel installer and request more information.

In August 2022, the ITC (now titled the Clean Energy Credit) was expanded and extended by the passing of the Inflation Reduction Act. Under the new program, solar installation projects started after January 1, 2022 and completed by the end of 2032 may be eligible for a 30% tax credit. This credit amount will then see a slight annual decrease until the end of the current Clean Energy Credit in 2035. Starting in 2023, the expansion to the program will also make claiming credit for energy storage systems easier than ever before.

More information about the new Inflation Reduction Act can be found here. Your local Killingly solar panel installation experts can answer any questions you have and explain how the new Clean Energy Credit may apply to you.

State & Local Solar Incentives

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

Next Steps for Installing Solar in Killingly

EcoWatch's Killingly, CT Solar Incentives FAQs

Can I get any financial 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 located within the United States that you own; most secondary residences fall under this distinction. Other solar incentives may be available for commercial properties, depending on the details. We recommend getting in touch with your local solar installer and/or tax professional to fully understand what incentives will apply to your specific situation.

How can I learn if I qualify for different solar incentives?

It's a good idea to talk to your local Killingly solar installer to get an understanding of which incentives your project may qualify for. In most cases, solar incentives apply to new solar systems installed on a property you own (in the U.S.) between the dates specified by the incentive. Some incentives, such as those offered by the government of Connecticut, might have additional requirements.

If my house already has solar panels, can I still claim incentives?

If your solar panels were installed after January 1, 2022, you may qualify for the newly increased 30% tax credit under the Inflation Reduction Act. If you had your system installed between 2006 and 2021, you may qualify for a tax credit between 26% and 30%, depending on the exact installation date. Reaching out to the company that installed your system, or any local Killingly solar installer, can help you learn more about what incentives you might want to apply for.

Can I apply for incentives both towards the up-front cost of solar panels, and later as reimbursement?

The order in which incentives are applied might vary depending on which incentives you are eligible for but typically yes, you can claim multiple types of incentives for your solar project. Talk with your solar installer or a local tax professional to ensure you are claiming all the incentives you are eligible for and applying them in the correct order.

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 wind and solar. You can also use both renewable energy sources and a backup source of non-renewable energy. You should discuss your plan with your local Killingly solar panel installer, to get an understanding of what will be needed and what kinds of incentives you will or won't qualify for.
