Solar incentives encourage people to make the switch to renewable energy by providing incentives that lower the financial burden of solar panel installation and use. Solar incentives might include cash back, upfront discounts or credit towards your monthly utility bill. Some incentives are given by the federal government, some by the state of Iowa and some by your specific utility company, county or municipality. You might qualify for any of the following types of solar incentives:

  • Tax Credits: These credits are dollar-for-dollar reductions (not deductions) in how much in taxes you owe the federal government.
  • Tax Exemptions: These may come in the form of property tax exemptions, which let you ignore 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.
  • Net Metering: Don't forget to talk to your Ottumwa utility company about signing a net metering contract. This allows you to get a credit towards your monthly utility bill for the value of excess energy generated by your solar panels. You could receive either a dollar-for-dollar credit or a percentage of the value.
  • Rebates: Some solar companies will help you claim a rebate, or partial refund of your purchase, for your solar system. States or counties will also sometimes offer limited-time rebates. If you receive a rebate, that amount will usually come off your total price before any tax credits are calculated.

Federal Solar Incentives

Federal incentives are the type of incentives that you are most likely to have heard of. A federal incentive many people are likely to be familiar with is the Federal Solar Investment Tax Credit (ITC). This is a tax credit for a specific percentage of the cost of your solar system.

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

To more fully understand how the ITC might apply to your situation, reach out to your local Ottumwa solar panel installation expert and ask for more information.

The Inflation Reduction Act, passed in August 2022, made some changes to the ITC (as well as retitling it the Clean Energy Credit). Homeowners can now receive a credit of 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 decrease on a yearly basis until the Clean Energy Credit expires in 2035. Starting in 2023, the expansion to the program 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 easiest way to learn more about how the new Clean Energy Credit will apply to you is to talk with your local Ottumwa solar panel installers.

State & Local Solar Incentives

In addition to those provided at the federal level, there are often also state solar incentives. Rebates, tax credits and more may be available at a more local level. These incentives may be offered by the Iowa government, or by your county or municipality. Certain incentives are ongoing, while others are available for a limited time.
