The term "solar incentives" refers to a 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. Incentives could include things like discounts, cash back or credit on your utility bill each month. Some incentives are provided by the federal government, while others are offered by the state of Connecticut or your specific utility company, county or municipality. Some solar incentives you might qualify for are:

  • Tax Exemptions: Your solar panel system could qualify for both sales tax and property tax exemptions. Sales tax exemptions come into effect at the time of purchase. Property tax exemptions let you exclude the value that solar panels add when you are calculating property taxes on your home.
  • Rebates: A rebate is a partial refund credited to your account after you've paid for your solar panels. Rebates may be offered by your local utility company, your state or your county. The rebates are usually applied before calculating tax credits.
  • Net Metering: You can sign a net metering contract with your Westport utility company, that may apply to all or a percentage of the excess electricity your solar panels generate. Your utility company will then subtract this value from your utility bill each month.
  • Tax Credits: Tax credits are dollar-for-dollar reductions that lower the amount of income tax you owe the government. (This is different from a tax deduction.)

Federal Solar Incentives

When people think of solar incentives, federal incentives might be the first thing that comes to mind. One of the incentives that most people are likely to be familiar with is the Federal Solar Investment Tax Credit (ITC). This incentive is a tax credit for a predetermined percentage of the cost of your solar system.

The ITC applies to the total cost of solar panel installation, including the panels themselves as well as accessories, equipment and labor. This credit can be claimed for panels installed after January 1, 2006, on a primary or secondary residence located in the United States that you own. Originally set at 30% of total costs, the credit has fluctuated over time, and you may qualify for different amounts depending on when your project was completed. There is no maximum amount you can claim.

To understand exactly how much money the ITC could save you, contact your local Westport solar panel installation expert.

In August 2022, the ITC (now titled the Clean Energy Credit) was expanded and extended by the passage of the Inflation Reduction Act. Homeowners are now eligible for a credit of 30% of the total solar system installation costs for projects started after January 1, 2022, and completed before the end of 2032. The credit percentage will then decrease yearly until the Clean Energy Credit ends in 2035. Starting in 2023, it will also be easier to obtain credits for energy storage systems under this new program.

State & Local Solar Incentives

Some solar incentives may be offered at the local or state level. Like with federal incentives, these might include rebates, tax credits and more. These incentives may be provided by the Connecticut government, or by your county or municipality. Some are ongoing, while others are available for a limited time.

Next Steps for Installing Solar in Westport

EcoWatch's Westport, CT Solar Incentives FAQs

How can I find out if I qualify for specific solar incentives?

Typically, solar incentives apply to:

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

Specific incentives, including those run by the Connecticut government or by your county/municipality, may have additional qualifications. Talk to your local Westport solar installer to learn more about what incentives your project may qualify for.

What are some environmental benefits of adding solar panels to my house?

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

If I change out my appliances for ones that utilize solar energy, are there any credits that I can claim?

The new Inflation Reduction Act includes provisions for several incentives designed to reward homeowners for making eco-friendly upgrades. Some incentives include rebates and tax credits for installing new electric appliances. You can find more details about these incentives here.

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

Yes, you can receive both rebates and tax credits towards the cost of solar panels. Depending on precisely which incentives you are claiming, they may apply in a different order. Make sure that you 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.

Can I use both solar and another type of renewable energy to power my home?

You can use multiple types of renewable energy, or a combination of renewable and non-renewable energy, to power your home. Be sure to talk through your ideas with your local Westport solar installer. They can help you plan your project and educate you on the various incentives that you might or might not qualify for.
