Solar incentives are designed to mitigate the cost of installing solar panels on your home. This category of financial incentives is in place to encourage more homeowners to switch their home over to renewable energy. Incentives may include things like discounts, cash back or credit on your utility bill each month. Some incentives are handled federally, while others are provided by the state of Connecticut or your specific utility company, county or municipality. Categories of solar incentives include:

  • Net Metering: Don't forget to talk with your Westport utility company about signing a net metering contract. This allows you to receive credit towards your utility bill every month for the value of excess energy your solar panels generate. You could receive either a dollar-for-dollar credit or a percentage of the value.
  • Tax Exemptions: Your solar system might qualify for exemptions on both sales and property tax. Sales tax exemptions come into effect at the time of purchase. Property tax exemptions allow you to ignore the value added by your solar panels when calculating property taxes on your house.
  • Tax Credits: Tax credits decrease, dollar-for-dollar, the total amount of tax you owe the government. These differ from tax deductions.
  • Rebates: Some solar companies will help you claim a rebate, or partial refund of your purchase, for your solar panels. States or counties will also sometimes offer limited-time rebates. Any rebates you receive will usually come off the total price before any tax credits are calculated.

Federal Solar Incentives

When people think of solar incentives, federal incentives might be the first thing that comes to mind. The solar incentive that you're most familiar with is probably the Federal Solar Investment Tax Credit (ITC), which gives you a credit on your taxes equal to a percentage of the cost of your solar system.

The ITC is applied to the total cost of installing a solar system, including the panels themselves as well as labor, accessories and equipment. This credit can be claimed for panels installed after January 1, 2006 on a primary or secondary residence that you own and that 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 claim amount.

Wondering how the ITC applies to your specific situation? Get in touch with your local Westport solar panel installation expert to get more information.

The Inflation Reduction Act, passed in August 2022, made some changes to the ITC (as well as renaming it to the Clean Energy Credit). The Clean Energy Credit has increased the current credit up to 30% for solar installation projects started after January 1, 2022 and completed by the end of 2032. After 2032, the credit percentage will see a slight decrease annually until the end of the program in 2035. Starting in 2023, the expansion to the program will also make credits for energy storage systems even easier to claim.

More information about the new Inflation Reduction Act can be found here. Your local Westport solar panel installers are the best people to answer your questions about the new Clean Energy Credit and how it applies to you.

State & Local Solar Incentives

Tax credits, rebates and more can be provided at multiple levels. On top of federal solar incentives, there are often state and local ones, too. Some incentives are offered for only a limited time, while others are ongoing. Your local solar incentives might come from your county or municipality, or from the Connecticut government.

EcoWatch's Westport, CT Solar Incentives FAQs

How much can I save on my electric bill annually if I add solar panels to my house in Westport?

Once you add solar panels to your Westport home, you can expect to save approximately $1,348.06 per year, or approximately $25,613.16 over the next 20 years.

What are some environmental benefits of adding solar panels to my house?

You can decrease your carbon footprint by 200 pounds of CO2 annually by switching to solar panels. This adds up to approximately 4,000 pounds over 20 years. Solar is also a renewable energy source, meaning that making the switch lessens the drain on our planet's resources.

I want to trade in my old appliances for ones that are more energy-efficient. Are there any benefits I can get?

The recently passed Inflation Reduction Act provides several incentives that reward homeowners who make eco-friendly upgrades. Some of these incentives include rebates and tax credits for installing new electric appliances. You can find more details about these incentives here.

Can I use multiple types of renewable energy to power my home?

Yes, you can use multiple types of renewable energy to power your home — for example, a combination of solar and geothermal. You can also use both renewable energy sources and a non-renewable backup source of energy. You should discuss the details of your plan with your local Westport solar installation expert, to make sure you know what you'll need and what types of incentives you may or may not qualify for.
