Solar incentives help mitigate the cost of installing solar panels on your home. This category of financial incentives is intended to encourage more Americans to make the switch to renewable energy. Incentives might include things like discounts, cash back or monthly utility bill credits. Some incentives are offered federally, while others are provided by the state of Connecticut or by your specific utility company, county or municipality. Categories of solar incentives include:

  • Tax Exemptions: Your solar panels may 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 ignore the value that solar panels add when you are calculating property taxes on your home.
  • Net Metering: You may be able to sign a net metering agreement with your Stonington utility company, that may apply to all or a percentage of the excess electricity that is generated by your solar panels. Your utility company will then deduct this value from your monthly utility bill.
  • Tax Credits: Different from tax deductions, tax credits reduce, dollar-for-dollar, the amount of income tax that you owe the government.
  • Rebates: Solar rebates may be offered by your local utility company, or by your state or county. These rebates work as cash back that is applied after you purchase a solar system and before tax credits are calculated.

Federal Solar Incentives

When someone says "solar incentives," you probably think of federal incentives first. The solar incentive that you're most familiar with is probably the Federal Solar Investment Tax Credit (ITC), which provides a credit on your taxes equal to a predetermined percentage of your solar system's cost.

The ITC applies towards solar systems installed after January 1, 2006 and allows you to deduct from your taxes a percentage of the total cost of solar panels, equipment, labor and accessories. This credit can be claimed on a solar panel system installed on a primary or secondary residence that you own in the United States. The original claim amount was 30% of the total cost, although depending on when the project was completed, your credit may range from 26-30%. There is no maximum claim amount.

Your local Stonington solar panel installer can provide more information about the ITC and how it applies to your situation.

In August 2022, the Inflation Reduction Act expanded and extended the ITC, now dubbed the Clean Energy Credit. Homeowners can now receive a credit equal to 30% of the total solar system installation costs for projects that began after January 1, 2022 and will be finished by the end of 2032. This percentage will then decrease annually until the Clean Energy Credit ends in 2035. The program expansion also makes it easier to get credit for energy storage systems, starting in 2023.

More information about the new Inflation Reduction Act can be found here. Your local Stonington solar panel installation expert is the best person to answer your questions regarding the new Clean Energy Credit and how it applies to you.

State & Local Solar Incentives

There are often state solar incentives available in addition to federal ones. Tax credits, rebates and more may be available at a more local level. These solar incentives — which may be handled by your county or municipality, or by the state of Connecticut — might be offered for only a limited time, or on an ongoing basis.

Next Steps for Installing Solar in Stonington

Solar incentives can come from your local utlity company, the Connecticut government or the federal government. The large number of available incentives has contributed to a large increase in solar energy use in the last 15 years.
