Solar incentives mitigate the cost of installing solar panels on your home. This category of financial incentives is designed to encourage more people to switch their home over to renewable energy. You may be eligible for different kinds of incentives, including 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 state of Delaware and others from the federal government. You might qualify for any of the following types of solar incentives:

  • Net Metering: Don't forget to speak to your Wilmington utility company about signing a net metering agreement. This allows you to get a credit towards your monthly utility bill for the value of excess energy your solar panels generate. You might receive either a dollar-for-dollar credit or a percentage of the value.
  • Rebates: Your solar installer might 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 be deducted from the total price before tax credits are calculated.
  • Solar Renewable Energy Certificate (SREC): SRECs and other similar performance-based incentives are usually handled by your state government. Once your solar system meets a certain threshold (usually a small amount of energy production), you can receive SRECs that you can then sell to your utility company or other buyers. The money you receive from the sale is usually considered part of your taxable income.
  • Tax Credits: Tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the government. (This is different from a tax deduction.)
  • Tax Exemptions: Tax exemptions can come in two forms. The first is sales tax exemption, applied at the time you purchase your solar panels. The second is property tax exemption. This allows you to ignore the added value of your solar system when paying property tax on your house.

Federal Solar Incentives

When people think of solar incentives, federal incentives might be the first thing that comes to mind. It's likely that you've heard of the Federal Solar Investment Tax Credit, or ITC. The ITC is a tax credit equal to a specified percentage of the money you spend on your solar system.

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

Your local Wilmington solar panel installer can offer more information about the ITC and how it applies to your situation.

The Inflation Reduction Act, passed in August 2022, added more provisions to the ITC (as well as retitling it the Clean Energy Credit). Under the new program, solar installation projects begun after January 1, 2022, and finished by December 31, 2032, might qualify for a 30% tax credit. This credit amount will then decrease slightly each year until the current Clean Energy Credit expires in 2035. Starting in 2023, the expansion will also make claiming credit for energy storage systems easier than ever before.

State & Local Solar Incentives

Some solar incentives are often also provided by state and local governments. Similar to federal incentives, these could include rebates, tax credits and more. These solar incentives — which might be provided by your county or municipality, or by the state of Delaware — might be offered on an ongoing basis, or for only a limited time.

Next Steps for Installing Solar in Wilmington

The variety of available solar incentives has contributed greatly to the increase in the use of solar power nationwide over the past 15 years. You might qualify for solar incentives from your local utility company, the Delaware government or the federal government. It is a good idea to talk to your local Wilmington solar installer to learn more about these incentives and to be sure that you're getting all the money you can for your solar panels.

How long until the federal solar tax credit ends?

The federal solar tax credit, formerly known as the ITC and now called the Clean Energy Credit, is set to end January 1, 2035. The current 30% credit will end in 2032, replaced by a 26% credit in 2033 and a 22% credit in 2034.

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 go over your ideas with your local Wilmington solar installer. They can help you with the plan for your project and give you an understanding of various incentives that you will or won't qualify for.
