Solar incentives are intended to make renewable energy usage more affordable via financial incentives to help people install solar panels on their homes. Incentives could include things like discounts, cash back or credit on your utility bill each month. Some incentives are handled federally, while others are provided by the state of Missouri or by your specific utility company, county or municipality. Some broad categories of solar incentives include:

  • Tax Credits: Tax credits decrease, dollar-for-dollar, how much income tax you owe the government. Tax credits differ from tax deductions.
  • Tax Exemptions: Your solar panels could qualify for exemptions on both sales and property tax. Sales tax exemptions come into effect at the time of purchase. Property tax exemptions let you ignore the added value of the solar panels when you are calculating property taxes on your house.
  • Rebates: Rebates, or partial refunds after a purchase, are usually given prior to any solar tax credits being calculated. These rebates might be given by your local utility company, by your county or by your state.
  • Net Metering: Be sure to talk to your St. Louis 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 your solar panels generate. You may receive either a dollar-for-dollar credit or a percentage of the value.

Federal Solar Incentives

When you think about solar incentives, you probably think of federal incentives first. The solar incentive that you may be most familiar with is the Federal Solar Investment Tax Credit (ITC), which provides a credit on your taxes equal to a certain percentage of the cost of your solar system.

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

Your local St. Louis solar panel installer can offer more information about the ITC and how it may apply to your situation.

The Inflation Reduction Act, passed in August 2022, made some changes to the ITC (as well as renaming it to the Clean Energy Credit). The Clean Energy Credit has increased the current credit up to 30% for solar installation projects started after January 1, 2022, and completed by the end of 2032. After 2032, the percentage will decrease slightly each year until the end of the program in 2035. The expansion to the program also makes credits for energy storage systems even easier to claim, beginning in 2023.

State & Local Solar Incentives

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

EcoWatch's St. Louis, MO Solar Incentives FAQs

My home already has solar panels installed. Does my system qualify for any incentives?

Your best bet is to talk to a representative from the company that installed your solar panels – or call a local St. Louis solar installer — to better understand which incentives you may qualify for. If your system was installed after January 1, 2022, you likely qualify for the recently 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 federal solar tax credit, formerly called the ITC and now named the Clean Energy Credit, is set 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 use both 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 solar and wind power. You can also use both renewable energy sources and a non-renewable backup source of energy. Be sure to discuss your plan with your local St. Louis solar panel installer, to make sure you know what you'll need and what kinds of incentives you may or may not qualify for.
