The term "solar incentives" generally refers to financial incentives implemented by the government and by solar companies to encourage the use of renewable energy by making installing and using solar panels more affordable. Incentives can include things like discounts, cash back or credit towards your monthly utility bill. Some incentives are offered federally, while others are handled by the state of Connecticut or by your utility company, county or municipality. You might qualify for any of the following types of solar incentives:

  • Net Metering: You can sign a net metering agreement with your Greenwich utility company. This agreement may apply to all or a percentage of the excess electricity that is generated by your solar panels. They will then subtract this value from your monthly utility bill.
  • Rebates: Solar rebates may be provided by your local utility company, or by your state or county. These rebates are essentially cash back that is applied after your purchase of a solar system and before tax credits are calculated.
  • Tax Exemptions: Your solar panels may 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 you are calculating property taxes on your house.
  • Tax Credits: Tax credits lower, dollar-for-dollar, the total amount of tax you owe the federal government. These are different from tax deductions.

Federal Solar Incentives

Federal solar incentives are likely the first thing that comes to mind when thinking about solar incentives. One of the incentives that most people are likely familiar with is the Federal Solar Investment Tax Credit (ITC). This incentive is a tax credit for a specified percentage of your solar system's cost.

The ITC is applied to the total cost of solar system installation, including the panels themselves as well as accessories, equipment and labor. 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. The tax credit ranges from 26-30% of total costs depending on when your project was completed. There is no maximum claim amount.

Your local Greenwich solar panel installer can give you more information about the ITC and how it may apply to your situation.

In August 2022, the Inflation Reduction Act laid out new provisions for the ITC, now titled the Clean Energy Credit. For solar system installations that begin after January 1, 2022, and are completed by the end of 2032, homeowners can apply for a credit equal to 30% of the total cost. After 2033, the percentage will decrease annually until the Clean Energy Credit ends in 2035. Beginning in 2023, it will also be easier to get credits for energy storage systems under this new program.

State & Local Solar Incentives

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