Solar incentives are intended to encourage people to switch to renewable energy by providing financial incentives meant to lower the burden of solar panel installation and use. The incentives might include cash back, upfront discounts or monthly credits towards your utility bill. Some incentives are given by the federal government, some by the state of Illinois and some by your utility company, county or municipality. Types of solar incentives might include:

  • Tax Credits: Tax credits are dollar-for-dollar reductions (not deductions) in how much in taxes you owe the federal government.
  • Rebates: A rebate is a partial refund after the purchase of your solar system. These might be offered by your local utility company, your state or your county. The cash back that you get from the rebates is normally applied before calculating tax credits.
  • Solar Renewable Energy Certificate (SREC): SRECs and other performance-based incentives may be available to you if you have a solar system that produces over a specified (usually small) amount of electricity. Performance-based incentives are normally handled at the state level. You can sell any SRECs you have to your utility company or other buyers, and the money you make is generally considered part of your taxable income.
  • Net Metering: Net metering factors in after your solar panels are up and running. If you have in place a net metering agreement with your Edwardsville utility company, it will subtract the value of the excess energy your solar system produces from your monthly utility bill. In some areas, this credit is dollar-for-dollar, while in others you might receive a refund equivalent to a percentage of the value.
  • Tax Exemptions: Tax exemptions may come in two forms. First, there is sales tax exemption, which is applied when you purchase solar panels. The second is property tax exemption, which allows you to ignore the value added by your solar system when calculating property tax for your home.

Federal Solar Incentives

Federal incentives are the type of incentives that you are most likely to have heard of. You've likely heard of the Federal Solar Investment Tax Credit, or ITC. This is a tax credit equal to a predetermined percentage of the money you spend installing solar panels.

The ITC applies to the value of solar panels installed on your primary or secondary residence in the United States. The solar panels have to have been installed after January 1, 2006, on a property you own for you to claim the credit. Initially, the ITC applied to 30% of all system installation costs (panels, equipment, accessories and labor), although this amount has fluctuated slightly over the last few years between 26-30%. The amount you qualify for will depend on when your solar system was installed. There is no cap on the claim amount.

Wondering how the ITC applies to your specific situation? Reach out to your local Edwardsville solar panel installer to get more information.

In August 2022, the Inflation Reduction Act expanded and extended the ITC, now dubbed the Clean Energy Credit. Homeowners can now qualify for a credit of 30% of the total solar system installation costs for projects that began after January 1, 2022, and will be finished by the end of 2032. This percentage will then begin to decrease yearly until the Clean Energy Credit ends in 2035. Starting in 2023, the program expansion will also make credits for energy storage systems even easier to claim.

State & Local Solar Incentives

Some solar incentives are often also provided at the state and local level. Similar to federal incentives, these may include tax credits, rebates and more. Some incentives are offered for only a limited time, while others are ongoing. Local solar incentives may come from your county or municipality, or from the Illinois government.

If I already have a solar system installed on my house, can I still claim incentives?

If your solar panels were installed after January 1, 2022, you likely qualify for the newly increased 30% tax credit under the Inflation Reduction Act. Solar systems installed between 2006 and 2021 may qualify for a tax credit of 26-30%.

How long until the federal solar tax credit ends?

The Clean Energy Credit (previously referred to as the federal solar tax credit, or the ITC), currently ends on January 1, 2035. Currently set at 30%, the credit will drop to 26% in 2033 and to 22% in 2034.

If I trade in my appliances for ones that use solar energy, are there credits I can claim?

The recently passed Inflation Reduction Act includes provisions for a number of incentives meant to reward homeowners for making eco-friendly upgrades. Some of these incentives include tax credits and rebates for installing new electric appliances. You can find more details about these incentives here.

What if I am planning to add a solar system to a vacation home, rental property or commercial property? Can I still qualify for incentives?

While we recommend speaking with your local solar installer and/or tax professional to best understand what solar incentives apply to you, many apply to a second home, so long as that home is in the United States and owned by you. There may be additional incentives available specifically for commercial properties, depending on the details.
