The term "solar incentives" covers 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. You may be eligible for various types 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 Connecticut government and others from the federal government. You might qualify for any of the following types of solar incentives:

  • Tax Exemptions: Your solar system could qualify for exemptions on both sales and property tax. Sales tax exemptions come into effect at the time of purchase. Property tax exemptions allow you to exclude the value added by your solar panels when calculating property taxes on your house.
  • Rebates: Rebates, or partial refunds after a purchase, are usually applied prior to any solar tax credits being calculated. These rebates can be provided by your local utility company, by your state or by your county.
  • Tax Credits: These credits are dollar-for-dollar reductions (not deductions) in how much income tax you owe the federal government.
  • Net Metering: Net metering factors in once your solar system is up and running. If you have a net metering agreement with your Wilton utility company, it will subtract the value of the excess energy your solar system produces from your utility bill each month. In some locations, this is a dollar-for-dollar credit, while in other places you might get refunded a percentage of the value.

Federal Solar Incentives

When you hear the term "solar incentives," federal incentives might be the first thing that comes to mind. You may have heard of the Federal Solar Investment Tax Credit, or ITC. This incentive is a tax credit that reduces your taxes by a predetermined percentage of the money you spend on your solar system.

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

To better understand how the ITC may apply to you, contact your local Wilton solar panel installer and request more information.

The Inflation Reduction Act, passed in August 2022, made some changes to the ITC (as well as retitling it the Clean Energy Credit). The Clean Energy Credit re-raises the credit up to 30% for solar installation projects started after January 1, 2022, and completed by the end of 2032. At this point, the percentage will decrease slightly each year until the program expires in 2035. Starting in 2023, the expansion to the program will also make credits for energy storage systems even easier to claim.

State & Local Solar Incentives

Some solar incentives may be provided by state and local governments. As with federal incentives, these can include tax credits, rebates and more. Incentives may be handled by your county or municipality, or by the state of Connecticut. Certain incentives are available for only a limited time, while others are ongoing.

Next Steps for Installing Solar in Wilton

The expanding number of solar incentives available has enormously increased the use of solar power nationwide over the past 15 years. You can get solar incentives from the federal government, the Connecticut government or from your local utility company. Reaching out to your local Wilton solar panel installation company is an excellent first step towards making sure you get all the incentives you qualify for when you switch to solar energy.
