The term "solar incentives" refers to a range of financial incentives implemented to make installing and using solar panels more affordable. This is done to encourage people to switch to renewable energy. These incentives may include cash back, upfront discounts or monthly credits towards your utility bill. Some incentives are offered 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:

  • Rebates: A rebate is a partial refund given after you've purchased your solar panels. These might be offered by your local utility company, your county or your state. The rebates are usually applied before calculating tax credits.
  • Tax Credits: Unlike tax deductions, tax credits reduce, dollar-for-dollar, the amount of income tax that you owe the federal government.
  • Tax Exemptions: Tax exemptions may come in one of two forms. The first is sales tax exemption, applied at the time you purchase your solar panels. The second is property tax exemption, which allows you to exclude the value added by your solar system when paying property tax on your house.
  • Net Metering: Net metering becomes relevant once your solar panels are up and running. If you've signed a net metering agreement with your Guilford utility company, they will subtract the value of the excess energy your solar system produces from your utility bill each month. In some locations, this credit is dollar-for-dollar, while in others you might make back a percentage of the value.

Federal Solar Incentives

Federal solar incentives are likely the first thing that comes to mind when you think about solar incentives. The Federal Solar Investment Tax Credit, or ITC, is the most commonly known federal solar incentive. The ITC provides a tax credit for a specific percentage of the cost of your solar system.

The ITC initially applied to 30% of the cost of solar system installation, although that number has fluctuated slightly over time between 26-30%. The installation date of your solar system will determine what percentage you qualify for. The cost of installation includes the panels themselves as well as the cost of equipment, labor and accessories. There is no maximum amount you can claim. The ITC can be applied to solar panels installed after January 1, 2006 on your primary or secondary residence. The residence must be in the United States and owned by you.

Have questions about how the ITC applies to your specific situation? Get in touch with your local Guilford solar panel installation expert to get more information.

The Inflation Reduction Act, passed in August 2022, added more provisions to the ITC (as well as renaming it to the Clean Energy Credit). Homeowners can now qualify for a credit of 30% of the total costs of solar system installation for projects that began after January 1, 2022 and will be finished by the end of 2032. This percentage will then decrease on a yearly basis until the Clean Energy Credit expires in 2035. Starting in 2023, the expansion to the program will also make credits for energy storage systems even easier to claim.

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

State & Local Solar Incentives

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

Next Steps for Installing Solar in Guilford

The nationwide use of solar energy has increased enormously in the past 15 years, in part due to the proliferation of solar incentives. You may get these incentives from your local utility company, the federal government or the Connecticut government. When you're prepared to make the change to solar energy, reaching out to your local Guilford solar panel installation expert is a great first step.

EcoWatch's Guilford, CT Solar Incentives FAQs

My home already has solar panels. Does my system qualify for any incentives?

Your best bet is to talk to the company that installed your solar system — or speak to a local Guilford solar installer — to clarify which incentives you may qualify for. If your solar panels were 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%.

How much will a solar system save me annually on my electric bill in Guilford?

Generally, homeowners in Guilford who install solar panels save about $1,341.13 per year, or about $25,481.41 over 20 years after making the switch.

How long until the federal solar tax credit ends?

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

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

Under the new Inflation Reduction Act, there are a number of new financial incentives to encourage you to make eco-friendly improvements to your home. More details on 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 use multiple types of renewable energy to power your home — for example, a combination of geothermal and solar. You can also use both renewable energy sources and a backup source of non-renewable energy. Make sure that you discuss the details of your plan with your local Guilford solar panel installer, so that you understand what you'll need and what incentives you might or might not qualify for.
