The term "solar incentives" refers broadly to financial incentives implemented by the government and by solar companies to encourage people to use renewable energy by making solar panels more affordable. Different types of incentives, including discounts, cash back or monthly utility bill credits, may be available to you. Some incentives may be offered by the Connecticut government, by your utility company or by county or municipality, while others are federal. You might qualify for any of the following types of solar incentives:

  • Tax Credits: Tax credits lower, dollar-for-dollar, the amount of income tax you owe the federal government. Tax credits are different from tax deductions.
  • Tax Exemptions: Your solar system could qualify for both sales tax and property tax exemptions. Sales tax exemptions are applied at the time of purchase. Property tax exemptions let you ignore the value that solar panels add when you are calculating property taxes on your home.
  • Rebates: Rebates, or partial refunds after a purchase, are typically applied before any solar tax credits are calculated. Solar rebates may be offered by your local utility company, by your state or by your county.
  • Net Metering: Be sure to talk with your Stamford 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 your solar panels generate. You might receive either a dollar-for-dollar credit or a percentage of the value.

Federal Solar Incentives

When you think about solar incentives, you likely think of federal incentives first. The Federal Solar Investment Tax Credit, or ITC, is the best-known federal solar incentive. The ITC allows you to claim a tax credit for a specific percentage of your solar system's cost.

The ITC can be applied to the total cost of solar system installation, including the panels themselves as well as equipment, labor and accessories. This credit can be claimed 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. 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.

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

In August 2022, the Inflation Reduction Act made revisions to the ITC, now dubbed the Clean Energy Credit. The Clean Energy Credit bolsters the current credit, increasing it up to 30% for solar installation projects started after January 1, 2022, and completed by the end of 2032. After this, the percentage will see a slight decrease annually until the end of the program in 2035. Starting in 2023, the expansion will also make claiming credit for energy storage systems easier than ever before.

State & Local Solar Incentives

Some solar incentives may be provided by state and local governments. Like with federal incentives, these may include tax credits, rebates and more. Some incentives are offered for only a limited time, while others are ongoing. Local solar incentives could come from your county or municipality, or from the Connecticut government.

EcoWatch's Stamford, CT Solar Incentives FAQs

I already have solar panels installed. Are there any incentives that I qualify for?

An excellent idea would be to talk to someone from the company that installed your system – or speak to a local Stamford solar installer — to learn about which incentives you might qualify for. If your system was installed after January 1, 2022, you likely qualify for the recently increased 30% tax credit under the Inflation Reduction Act. Solar systems installed between 2006 and 2021 may qualify for a tax credit of 26-30%.

How long until the federal solar tax credit ends?

The Clean Energy Credit (previously called the federal solar tax credit, or the ITC), currently ends on January 1, 2035. Currently set at 30%, the credit will drop to 26% in 2033 and to 22% in 2034.

Can I apply for incentives both towards the initial cost of solar panels, and later as reimbursement?

The order that incentives will be applied in may vary depending on which incentives you receive but generally yes, you can claim multiple types of incentives for your solar project. Get in touch with your solar installer or a local tax professional to verify you are claiming all the incentives you're eligible for and applying them in the correct order.
