Solar incentives are designed to make renewable energy usage more affordable via financial incentives for those who install solar panels on their homes. You may be eligible for various kinds of incentives, such as cash back, discounts or monthly utility bill credits, depending on your situation. Some incentives come from your specific utility company, county or municipality, some from the Illinois government and others from the federal government. Some solar incentives you might qualify for are:

  • Solar Renewable Energy Certificate (SREC): SRECs and other similar performance-based incentives are usually handled by your state government. Once your solar panel system meets a certain threshold (generally a small amount of energy production), you are eligible to receive SRECs that can then be sold to your utility company or other buyers. The money you make 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 federal government. (This is different from a tax deduction.)
  • Rebates: Solar rebates may be provided by your county or state, or by your local utility company. These rebates are essentially cash back that is applied after you pay for solar panels and before tax credits are calculated.
  • Net Metering: You can sign a net metering agreement with your Charleston utility company, that may apply to all or a percentage of the excess electricity your solar panels generate. They will then deduct this value from your monthly utility bill.
  • Tax Exemptions: These could come in the form of property tax exemptions, which can let you ignore the value of your solar system when paying property tax on your house. You could also look for exemptions on sales tax at the time of purchase.

Federal Solar Incentives

Federal solar incentives are likely to be the first thing that you think of when you think about solar incentives. The Federal Solar Investment Tax Credit, or ITC, is probably the most commonly known federal solar incentive. The ITC offers a tax credit for a specific percentage of your solar system's cost.

The ITC applies to the value of solar panels installed on your primary or secondary residence in the United States. The solar system must have been installed on a property you own after January 1, 2006, for you to claim the credit. The ITC initially covered 30% of all costs (panels, accessories, equipment and labor), although the amount has fluctuated 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 amount you can claim.

To better understand exactly how much money the ITC could save you, contact your local Charleston solar panel installation expert.

In August 2022, the Inflation Reduction Act laid out new provisions for the ITC, now dubbed the Clean Energy Credit. With the new provisions, solar installation projects begun after January 1, 2022, and finished by December 31, 2032, may be eligible for a 30% tax credit. This credit amount will then decrease slightly each year until the current Clean Energy Credit expires in 2035. The expansion to the program also makes credits for energy storage systems even easier to claim, beginning in 2023.

More information about the new Inflation Reduction Act can be found here. To best understand how the new Clean Energy Credit will apply to you, get in touch with your local Charleston solar installers.

State & Local Solar Incentives

Some solar incentives may be offered at the local or state level. Like with federal incentives, these may include rebates, tax credits and more. These incentives — which might be provided by your county or municipality, or by the state of Illinois — could be offered for only a limited time, or on an ongoing basis.

Next Steps for Installing Solar in Charleston

Solar energy use nationwide has significantly increased in the last 15 years, in part due to the growth in the number of solar incentives. You can obtain these incentives from the federal government, the Illinois government or your local utility company. If you're ready to switch over to solar energy, reaching out to your local Charleston solar panel installation expert is an excellent place to start.
