Solar incentives are designed to mitigate the cost of installing solar panels on your home. These financial incentives are intended to encourage more Americans to switch their home over to renewable energy. Incentives could include things like discounts, cash back or credit on your utility bill each month. Some incentives are offered federally, while others are offered by the state of Connecticut or your specific utility company, county or municipality. Some broad categories of solar incentives include:

  • Net Metering: Net metering is an incentive you can get once your solar system is up and running. If you have a net metering agreement with your Darien utility company, the company will subtract the value of the excess energy produced by your solar system from your monthly utility bill. In some places, this is a dollar-for-dollar credit, while in other places you may make back a percentage of the value.
  • Tax Exemptions: Your solar panels could qualify for exemptions on both sales and property tax. Sales tax exemptions come into effect at the time of purchase. Property tax exemptions let you ignore the added value of the solar panels when calculating property taxes on your home.
  • Rebates: A solar rebate is a partial refund credited to your account after you've paid for your solar panels. These may be offered by your local utility company, your county or your state. The rebates are usually applied before calculating tax credits.
  • 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.)

Federal Solar Incentives

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

The ITC can be applied to the total cost of installing a solar system, including the panels themselves as well as accessories, labor and equipment. You can claim this credit for panels installed after January 1, 2006 on a primary or secondary residence located in the United States that you own. From its original value of 30% of the total cost, the credit has fluctuated slightly between 26-30%, and you may qualify for varying percentages depending on when your project was completed. There is no maximum amount you can claim.

Wondering how the ITC applies to your specific situation? Reach out to your local Darien solar panel installation expert to get more information.

In August 2022, the Inflation Reduction Act expanded and extended the ITC, now dubbed the Clean Energy Credit. The Clean Energy Credit lasts 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 then decrease slightly each year until the end of the current program. Beginning in 2023, it will also be easier to claim credits for energy storage systems with the new act.

State & Local Solar Incentives

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

EcoWatch's Darien, CT Solar Incentives FAQs

How do I learn if I qualify for specific solar incentives?

Broadly, solar incentives apply to:

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

Specific incentives, including those run by the Connecticut government or by your county/municipality, may have additional qualifications. Get in touch with your local Darien solar installer to learn more about what incentives your project will qualify for.

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 recently increased 30% tax credit under the Inflation Reduction Act. If you installed your system between 2006 and 2021, you might qualify for a tax credit between 26% and 30%, depending on the date of installation. Reaching out to the company that installed your system, or any local Darien solar installer, can help you learn what incentives you qualify for.

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

You can decrease your carbon footprint by 200 pounds of CO2 a year when you switch to solar panels. This adds up to roughly 4,000 pounds over 20 years. Solar is also a renewable energy source, meaning that switching your home over reduces the drain on our planet's resources.

I want to switch my appliances out for ones that are more energy-efficient. Are there any benefits I can apply for?

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