Solar incentives mitigate the cost of installing solar panels on your home. Financial incentives like these are in place to encourage more Americans to switch their home over to renewable energy. You may qualify for several types of incentives, such as cash back, discounts or credit towards your monthly utility bill, depending on your situation. Some incentives come from your specific utility company, county or municipality, some from the Connecticut government and others from the federal government. Some broad categories of solar incentives include:

  • Net Metering: You can sign a net metering contract with your Derby utility company that will apply to all or a percentage of the excess electricity your solar panels generate. Your utility company will then deduct this value from your utility bill each month.
  • Rebates: Solar rebates might be provided by your county or state, or by your local utility company. These rebates work as cash back that is applied after you purchase solar panels and before tax credits are calculated.
  • Tax Credits: Tax credits are dollar-for-dollar reductions (not deductions) in the amount of tax that you owe the federal government.
  • Tax Exemptions: Tax exemptions can come in one of two forms. First, there is sales tax exemption, applied when you purchase solar panels. The second is property tax exemption, which allows you to ignore the added value of your solar system when calculating property tax for your house.

Federal Solar Incentives

When someone says "solar incentives," you likely think of federal incentives first. You may have heard of the Federal Solar Investment Tax Credit, or ITC. This is a tax credit that reduces your taxes by a specified percentage of the money you spend on your solar system.

The ITC applies to solar panels installed after January 1, 2006, on a primary or secondary residence in the United States that you own. Initially, the credit applied to 30% of the total cost – for panels, equipment, labor and accessories – although that amount may range from 26-30%, depending on the installation date of your solar system. There is no cap on the amount you can claim.

To more fully understand how the ITC will apply to you, contact your local Derby solar panel installation expert and request more information.

The ITC was both renewed and expanded by the passage of the Inflation Reduction Act in August 2022. It's also now called the Clean Energy Credit. For solar systems installed between January 1, 2022, and December 31, 2032, homeowners can receive a credit for 30% of the total cost. This percentage will decrease annually after 2032 until the Clean Energy Credit ends in 2035. The program expansion also makes claiming credit for energy storage systems easier than ever before, beginning in 2023.

State & Local Solar Incentives

In addition to federal solar incentives, there are often also state ones. Tax credits, rebates and more can be offered at a more local level. Some incentives are ongoing, while others might only be available for a limited time. These incentives might be given by the Connecticut government, or by your county or municipality.

Next Steps for Installing Solar in Derby

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

Yes, you can receive both rebates and tax credits towards the cost of your solar panels. Depending on which incentives you are receiving, they may apply in a different order. Be sure to speak with your solar installer or a local tax professional to ensure that you are claiming incentives correctly and getting the most money possible.

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 ideas with your local Derby solar installer. They can help you with the plan for your project and also help you understand the various incentives that you might or might not qualify for.
