The phrase "solar incentives" 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 may include things like discounts, cash back or monthly utility bill credits. Some incentives are provided by the federal government, while others are offered by the state of Connecticut or your specific utility company, county or municipality. Some solar incentives you might qualify for are:

  • Net Metering: You can sign a net metering agreement with your Fairfield utility company that will 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.
  • Tax Credits: Tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the government. (A tax credit is different from a tax deduction.)
  • Tax Exemptions: These may come in the form of property tax exemptions, which allow you to ignore the value added by your solar panels when paying taxes on your house. You may also qualify for an exemption on sales tax at the time of purchase.
  • Rebates: A rebate is a partial refund given after you've purchased your solar system. Rebates may be offered by your local utility company, your county or your state. The rebates are usually applied before tax credits are calculated.

Federal Solar Incentives

Federal solar incentives are likely the first thing that comes to mind when thinking about solar incentives. 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 specified percentage of the cost of your solar system.

The ITC can be applied to the total cost of installing solar panels, 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. The tax credit ranges from 26-30% of total costs depending on when your project was completed. There is no maximum claim amount.

To best understand how the ITC could apply to you, get in touch with your local Fairfield solar panel installation expert and ask for more information.

In August 2022, the Inflation Reduction Act expanded and extended the ITC, now called the Clean Energy Credit. The Clean Energy Credit is valid until 2035. Your solar installation project undertaken between 2022 and 2032 may qualify for a 30% tax credit. The amount will be decreased slightly on a yearly basis until the end of the current program. The program expansion also makes it easier to get credit for energy storage systems, beginning in 2023.

More information about the new Inflation Reduction Act can be found here. The easiest way to learn more about how the new Clean Energy Credit might apply to you is to speak with your local Fairfield solar panel company directly.

State & Local Solar Incentives

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

EcoWatch's Fairfield, CT Solar Incentives FAQs

Can I get any financial incentives when I add solar panels to a vacation home, rental property or commercial property?

While we recommend talking to your local solar installer and/or tax professional to better understand what solar incentives apply to you, many incentives can be claimed on a second home, provided that it is in the United States and owned by you. There may be additional incentives available for commercial properties specifically, depending on the details.

What are some environmental benefits of installing solar panels on my house?

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

I want to switch my appliances out for ones that are more energy-efficient. Are there any benefits I can claim?

Under the new Inflation Reduction Act, there are a variety of new financial incentives for making eco-friendly improvements to your home. More details about these incentives, including information about incentives for purchasing new appliances, can be found here.

Can I claim incentives both towards the up-front cost of solar panels, and later as reimbursement?

The order in which incentives are applied could vary depending on which incentives you are claiming but usually yes, you can receive multiple types of incentives for your solar project. Get in touch with your solar installer or a local tax professional to be sure you are claiming all possible incentives and applying them in the correct order.

Can I use solar and another type of renewable energy in combination to power my home?

You can use multiple types of renewable energy, or a combination of renewable and non-renewable energy, to power your home. Be sure to discuss your plan with your local Fairfield solar installer. They can help you with the plan for your project and also help you understand the various incentives that you may or may not qualify for.
