The term "solar incentives" generally refers to financial incentives that are in place to encourage increased use of renewable energy by making installing and using solar panels more affordable. The incentives can include upfront discounts, cash back or credit towards your monthly utility bill. Some incentives are given by the federal government, some by the state of Connecticut and some by your specific utility company, county or municipality. Some broad categories of solar incentives include:

  • Tax Exemptions: Tax exemptions may come in one of two forms. First, there is sales tax exemption, which is applied when you purchase solar panels. The second is property tax exemption. This allows you to exclude the added value of your solar system when calculating property tax for your house.
  • Rebates: Some solar companies will help you claim a rebate, or partial refund after purchase, for your solar panels. Counties or states will also sometimes offer limited-time rebates. Any rebates you receive will usually come off the total price before tax credits are calculated.
  • Net Metering: You can sign a net metering agreement with your Plymouth utility company that will apply to all or a percentage of the excess electricity that is generated by your solar panels. They will then deduct this value from your monthly utility bill.
  • Tax Credits: Tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the government. (A tax credit is different from a tax deduction.)

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 most commonly known federal solar incentive. The ITC provides a tax credit for a predetermined 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 panels must have been installed after January 1, 2006 on a property owned by you for you to claim the credit. Originally, the ITC covered 30% of all system costs (panels, labor, equipment and accessories), although the total amount has fluctuated slightly over time 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.

To more fully understand how the ITC may apply to you, contact your local Plymouth solar panel installation expert and request 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. The Clean Energy Credit is valid until 2035. Any solar installation project that is completed between January 1, 2022 and December 31, 2032 may qualify for a 30% tax credit. This amount will be decreased slightly each year until the end of the current program. Starting in 2023, the expansion to the program will also make credits for energy storage systems even easier to claim.

State & Local Solar Incentives

There are often also state solar incentives in addition to those provided by the federal government. Tax credits, rebates and more may be available at a more local level. Some incentives are ongoing, while others might only be available for a limited time. Incentives might be provided by the Connecticut government, or by your county or municipality.

Next Steps for Installing Solar in Plymouth

Solar incentives might come from your local utility company, the federal government or the Connecticut government. The large number of solar incentives available has contributed to a large increase in solar energy use in the last 15 years. When you're prepared to switch over to solar energy, getting in touch with your local Plymouth solar panel installation expert is an excellent place to start.

EcoWatch's Plymouth, CT Solar Incentives FAQs

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

While we recommend talking to your local solar installer and/or tax professional to fully understand what solar incentives apply to you, many incentives can be claimed on a second home, so long as that home is in the United States and owned by you. There may be other incentives available for commercial properties specifically, depending on the specifics.

I already have solar panels installed. Are there any incentives that I qualify for?

An excellent idea would be to talk to a representative from the company that installed your system — or get in touch with a local Plymouth solar installer — to clarify which incentives you might qualify for. If your system was installed after January 1, 2022, you likely qualify for the newly 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%.

When does the federal solar tax credit end?

The federal solar tax credit, previously called the ITC and now called the Clean Energy Credit, is slated to end on January 1, 2035. The current 30% credit will end in 2032, replaced by a 26% credit in 2033 and a 22% credit in 2034.

I want to change out my appliances for ones that are more energy-efficient. Are there any credits I can claim?

The new Inflation Reduction Act creates a variety of new financial incentives that are available when you make eco-friendly improvements to your home. More details regarding these incentives, including information about incentives for purchasing new appliances, can be found here.

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

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