Solar incentives are meant to encourage homeowners to switch their home over to renewable energy by offering financial incentives that lower the burden of solar panel installation and use. The incentives may include upfront discounts, cash back or monthly credits towards your utility bill. Some incentives are provided by the federal government, some by the Missouri government and some by your utility company, county or municipality. You might qualify for any of the following types of solar incentives:

  • Net Metering: Make sure you speak to your Wentzville utility company about signing a net metering agreement. This allows you to receive credit towards your utility bill every month 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.
  • Tax Exemptions: These could come in the form of property tax exemptions, which let you exclude the value added by your solar panels when paying property tax on your home. You may also qualify for an exemption on sales tax at the time of purchase.
  • Rebates: Some solar companies will help you claim a rebate, or partial refund after purchase, for your solar panels. Counties or states will also offer limited-time rebates at various times. Any rebates you receive will usually be deducted from the total price before any tax credits are calculated.
  • Tax Credits: Different from tax deductions, tax credits reduce, dollar-for-dollar, the amount of income tax that you owe the government.

Federal Solar Incentives

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

The ITC originally covered 30% of the cost of solar system installation, although that number has fluctuated slightly over the years between 26-30%. The installation date of your solar system will determine what percentage you qualify for. The total cost of installation includes the panels themselves as well as the cost of labor, equipment and accessories. There is no maximum amount you can claim. The ITC applies to solar panels installed after January 1, 2006, on your primary or secondary residence. The residence must be in the United States and owned by you.

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

In August 2022, the Inflation Reduction Act laid out new provisions for the ITC, now referred to as the Clean Energy Credit. The Clean Energy Credit bolsters the current credit, increasing it up to 30% for solar installations undertaken between January 1, 2022, and December 31, 2032. After 2032, the percentage will decrease slightly each year until the end of the program in 2035. Starting in 2023, the program expansion will also make credits for energy storage systems even easier to claim.

More information about the new Inflation Reduction Act can be found here. The best way to understand how the new Clean Energy Credit will apply to you is to reach out to your local Wentzville solar panel company with your questions.

State & Local Solar Incentives

Tax credits, rebates and more can be claimed at multiple levels. On top of federal solar incentives, there are often state and local ones as well. Incentives may be provided by your county or municipality, or by the state of Missouri. Certain incentives are available for only a limited time, while others are ongoing.
