Solar incentives help mitigate the cost of installing a solar panel system on your home. This category of financial incentives is intended to encourage more homeowners to convert their home partially or fully to renewable energy. Solar incentives can include upfront discounts, cash back or monthly credits towards your utility bill. Some incentives are handled by the federal government, some by the Connecticut government and some by your utility company, county or municipality. Categories of solar incentives include:

  • Tax Credits: These credits are dollar-for-dollar reductions (not deductions) in how much in taxes you owe the government.
  • Net Metering: Net metering factors in once your solar panels are up and running. If you have a net metering agreement in place with your Old Lyme utility company, they will subtract the value of the excess energy your solar system produces from your utility bill each month. In some areas, this credit is dollar-for-dollar, while in other areas you may make back a percentage of the value.
  • Rebates: Rebates, or cash back after a purchase, are usually applied before any solar tax credits are calculated. These rebates can be given by your local utility company, by your county or by your state.
  • Tax Exemptions: Your solar system may qualify for exemptions on both sales and property tax. Sales tax exemptions are applied at the time of purchase. Property tax exemptions allow you to exclude the value that solar panels add when you are calculating property taxes on your home.

Federal Solar Incentives

Federal incentives are the kind of incentives that you are most likely to have some knowledge of. One of the incentives many people are probably familiar with is the Federal Solar Investment Tax Credit (ITC). This is a tax credit for a specified percentage of the cost of your solar system.

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

Have questions about how the ITC applies to your specific situation? Contact your local Old Lyme solar panel installer to get more information.

The Inflation Reduction Act, passed in August 2022, added more provisions to the ITC (as well as retitling it the Clean Energy Credit). Now, solar installation projects that are completed between 2022 and 2032 might qualify for a 30% tax credit. This percentage will then decrease slightly each year until the current Clean Energy Credit expires in 2035. The expansion also makes claiming credit for energy storage systems easier than ever before, starting in 2023.

More information about the new Inflation Reduction Act can be found here. The best way to learn more about how the new Clean Energy Credit applies to you is to talk with your local Old Lyme solar panel company.

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 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.

Next Steps for Installing Solar in Old Lyme

There are a variety of solar incentives: those offered by local utility companies, those offered by the federal government and those offered by the Connecticut government, to name a few. Solar energy utilization has grown tremendously in the last 15 years, partially due to these incentives. We recommend talking to your local Old Lyme solar installation company to learn more about these incentives and to be sure that you're getting all of the money you can for your solar system.
