Solar incentives help mitigate the cost of installing solar panels on your home. This category of financial incentives is designed to encourage more people to convert their home partially or fully to renewable energy. You may qualify for several kinds of incentives, such as cash back, discounts or monthly utility bill credits, depending on your situation. Certain incentives come from your specific utility company, county or municipality, some from the Iowa government and others from the federal government. Some broad categories of solar incentives include:

  • Tax Credits: Unlike tax deductions, tax credits reduce, dollar-for-dollar, the amount of income tax that you owe the federal government.
  • Tax Exemptions: Your solar panels could qualify for exemptions on both sales and property tax. Sales tax exemptions are effective at the time of purchase. Property tax exemptions allow you to exclude the value that solar panels add when you are calculating property taxes on your house.
  • Net Metering: Net metering factors in once your solar system is up and running. If you've signed a net metering agreement with your Ottumwa utility company, the company will subtract the value of the excess energy your solar system produces from your monthly utility bill. In some locations, this credit is dollar-for-dollar, while in other places you may make back a percentage of the value.
  • Rebates: Solar rebates can be provided by your local utility company, or by your county or state. These rebates are essentially partial refunds that are applied after your purchase of solar panels and before tax credits are calculated.

Federal Solar Incentives

When someone says "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 gives you a credit on your taxes equal to a specified percentage of the cost of your solar system.

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

Your local Ottumwa 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 retitling it the Clean Energy Credit). For solar system installations that begin after January 1, 2022, and are completed by the end of 2032, homeowners can apply for a credit equal to 30% of the total cost. The percentage will then decrease annually until the Clean Energy Credit ends in 2035. Beginning in 2023, it will also be easier to qualify for credits for energy storage systems under the new laws.

State & Local Solar Incentives

Tax credits, rebates and more might be claimed at multiple levels. On top of federal solar incentives, there are often state and local ones, too. Some incentives are ongoing, while others are available for a limited time. Solar incentives might be provided by your county or municipality, or by the Iowa government.

Next Steps for Installing Solar in Ottumwa

Can I apply for incentives both towards the up-front cost of solar panels, and later as reimbursement?

The order in which incentives are applied might vary depending on which incentives you are eligible for but in most cases yes, you can claim multiple types of incentives for your solar project. Talk with your solar installer or a local tax professional to be sure you are claiming all the incentives you qualify for and applying them in the correct order.

What if I want to add solar panels to a rental property, vacation home or commercial property? Can I still qualify for incentives?

While we recommend speaking with your local solar installer and/or tax professional to better understand what solar incentives apply to you, many can be claimed on a second home, provided that it is in the United States and owned by you. There may be additional incentives available specifically for commercial properties, depending on the specifics.
