Solar incentives mitigate the cost of installing solar panels on your home. These financial incentives are in place to encourage more Americans to switch to renewable energy. Different types of incentives, like cash back, discounts or monthly utility bill credits, might be available to you. Some incentives may be provided via the Connecticut government, by your utility company or by county or municipality, while others are federal. Types of solar incentives might include:

  • Tax Exemptions: Tax exemptions can come in two forms. The first is sales tax exemption, which is applied at the time you purchase your solar panels. The second is property tax exemption. This allows you to ignore the value added by your solar system when paying property tax on your house.
  • Rebates: Solar companies may help you claim a rebate, or partial refund of your purchase, for your solar system. States or counties will also offer limited-time rebates at various times. The value of a rebate will usually come off the total price before any tax credits are calculated.
  • Tax Credits: These credits are dollar-for-dollar reductions (not deductions) in how much in taxes you owe the government.
  • Net Metering: Make sure you talk to your Wilton utility company about signing a net metering agreement. This will allow you to receive credit towards your utility bill every month for the value of excess energy generated by your solar panels. You could receive either a dollar-for-dollar credit or a percentage of the value.

Federal Solar Incentives

When you think about solar incentives, you probably think of federal incentives first. It's likely that you've 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 can be applied to the total cost of solar panel installation, including the panels themselves as well as accessories, equipment and labor. You can claim this credit for panels installed after January 1, 2006, on a primary or secondary residence that you own, as long as it is located in the United States. 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 claim amount.

Have questions about how the ITC applies to your specific situation? Get in touch with your local Wilton solar panel installer to get 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). 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. This percentage will then decrease on a yearly basis until the Clean Energy Credit ends in 2035. The expansion also makes it easier to get credit for energy storage systems, beginning in 2023.

State & Local Solar Incentives

There are more than just federal solar incentives; rebates, tax credits and more might also be offered at the state and local level. These solar incentives — which might be given by your county or municipality, or by the state of Connecticut — could be offered on an ongoing basis, or for only a limited time.

Next Steps for Installing Solar in Wilton

Your local Wilton solar panel installer can help you learn more about which incentives you should apply for, and get you on track to switch to renewable energy today.

With the passage of 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 about these incentives, including information about incentives for purchasing new appliances, can be found here.

Can I claim incentives for adding solar panels to a rental property, vacation home or commercial property?

While we recommend talking to your local solar installer and/or tax professional to fully understand what solar incentives apply to you, many incentives will apply to 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.
