The term "solar incentives" refers broadly to financial incentives put in place by solar companies and the government to encourage the use of renewable energy by making the installation and use of solar panels more affordable. Various kinds of incentives, including cash back, discounts or monthly utility bill credits, might be available to you. Some incentives may be offered by the Illinois government, by your utility company or by county or municipality, while others are federal. You might qualify for any of the following types of solar incentives:

  • Tax Exemptions: Tax exemptions can come in two forms. The first is sales tax exemption, applied when you purchase solar panels. The second is property tax exemption. This allows you to exclude the added value of your solar system when paying property tax on your house.
  • Tax Credits: Different from tax deductions, tax credits reduce, dollar-for-dollar, the amount of income tax that you owe the federal government.
  • Solar Renewable Energy Certificate (SREC): SRECs are credits that can be sold to your utility company (or other buyers) for money that is generally considered part of your taxable income. In most cases, a certain (small) threshold of energy production must be met before your solar system can earn SRECs or other performance-based incentives. These kinds of incentives are normally handled by your state government.
  • Rebates: Solar rebates might be provided by your local utility company, or by your county or state. These rebates work as cash back that is applied after your purchase of a solar system and before tax credits are calculated.
  • Net Metering: Make sure you talk to your St. Charles utility company about signing a net metering contract. This will allow you to get a credit towards your monthly utility bill for the value of excess energy generated by your solar panels. You might receive either a dollar-for-dollar credit or a percentage of the value.

Federal Solar Incentives

Federal solar incentives are likely the first thing that you think of when thinking about solar incentives. It's likely that you've heard of the Federal Solar Investment Tax Credit, or ITC. This incentive is a tax credit that reduces your taxes by a predetermined percentage of the money you spend installing solar panels.

The ITC can be applied to the total cost of solar panel installation, 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, as long as it is located in the United States. From its original value of 30% of the total cost, the credit has fluctuated slightly between 26-30%, and you may qualify for varying percentages depending on when your project was completed. There is no maximum claim amount.

To better understand exactly how much money the ITC could save you, get in touch with your local St. Charles solar panel installation expert.

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. Homeowners are now eligible for a credit equal to 30% of the total costs of solar system installation for projects that began after January 1, 2022, and will be finished by the end of 2032. This percentage will then begin to decrease on a yearly basis until the Clean Energy Credit ends in 2035. Starting in 2023, the expansion will also make it easier to get credit for energy storage systems.

More information about the new Inflation Reduction Act can be found here. The best way to fully understand how the new Clean Energy Credit applies to you is to speak with your local St. Charles solar panel installers directly.

State & Local Solar Incentives

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

EcoWatch's St. Charles, IL Solar Incentives FAQs

If I already have solar panels, can I still claim incentives?

If your solar system was installed after January 1, 2022, you may qualify for the recently increased 30% tax credit under the Inflation Reduction Act. If your system was installed between 2006 and 2021, you may qualify for a tax credit between 26% and 30%, depending on the exact installation date. Speaking with the company that installed your system, or any local St. Charles solar installer, can help you learn what incentives you might want to apply for.

When does the federal solar tax credit end?

The federal solar tax credit, formerly known as the ITC and now called the Clean Energy Credit, is slated to end on 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 receive incentives both towards the up-front cost of solar panels, and later as reimbursement?

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

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

Yes, you can utilize multiple types of renewable energy to power your home — for example, a combination of wind and solar. You can also combine renewable energy generation with a non-renewable backup source of energy. You should discuss the details of your plan with your local St. Charles solar panel installer, to make sure you know what you'll need and what incentives you might or might not qualify for.

Can I claim incentives for adding solar panels to a rental property, vacation home or commercial property?

Many solar incentives apply to a property located within the United States that you own, and most secondary residences will fall under this distinction. There may be other solar incentives available for commercial properties, depending on the specifics. We recommend speaking with your local solar installer and/or tax professional to best understand what incentives will apply to your specific situation.
