The term "solar incentives" broadly refers to financial incentives put in place by solar companies and the government to encourage the adoption and use renewable energy by making the installation and use of solar panels more affordable. The incentives can include cash back, upfront discounts or monthly credits towards your utility bill. Some incentives are given by the federal government, some by the Iowa government and some by your utility company, county or municipality. Categories of solar incentives include:

  • Tax Exemptions: Tax exemptions can come in two forms. The first is sales tax exemption, which is applied at the time you purchase your solar panels. The second is property tax exemption. This allows you to ignore the added value of your solar system when calculating property tax for your house.
  • 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.)
  • Net Metering: You may be able to sign a net metering contract with your Marion utility company, that may apply to all or a percentage of the excess electricity your solar panels generate. Your utility company will then subtract this value from your monthly utility bill.
  • Rebates: Solar rebates can be provided by your local utility company, or by your county or state. These rebates are essentially cash back that is applied after you purchase solar panels and before tax credits are calculated.

Federal Solar Incentives

When people think of solar incentives, federal incentives might be the first thing that comes to mind. A federal incentive that most 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 can be applied to solar systems installed after January 1, 2006, on a primary or secondary residence that you own in the United States. Initially, the credit applied to 30% of the total cost – for panels, labor, equipment and accessories – although it may range from 26-30%, depending on the installation date of your solar system. There is no cap on the amount you can claim.

To better understand exactly how much the ITC could save you, contact your local Marion solar panel installer.

In August 2022, the ITC (now called the Clean Energy Credit) was expanded and extended by the passage of the Inflation Reduction Act. The new Clean Energy Credit is valid until 2035. Homeowners can now receive a 30% credit for solar systems that began installation after January 1, 2022, and are completed by the end of 2032. The credit will then be decreased by a few percentage points every year until its expiration. Starting in 2023, the expansion to the program will also make claiming credit for energy storage systems easier than ever before.

More information about the new Inflation Reduction Act can be found here. The best way to fully understand how the new Clean Energy Credit will apply to you is to speak with your local Marion solar panel installers directly.

State & Local Solar Incentives

Some solar incentives may be provided by state and local governments. Similar to federal incentives, these may include rebates, tax credits and more. Incentives might be handled by your county or municipality, or by the state of Iowa. Certain incentives may be available for only a limited time, while others are ongoing.

Next Steps for Installing Solar in Marion

There are many types of solar incentives: those provided by local utility companies, those offered by the Iowa government and those given by the federal government, to name a few. The use of solar energy has grown enormously in the last 15 years, partially due to these incentives.

What are some of the environmental benefits of switching to solar?

You can lower your carbon footprint by 450 pounds of CO2 annually by switching to solar panels. This adds up to approximately 9,000 pounds in 20 years. Solar is also a renewable energy source, which means that making the switch reduces the drain on our planet's resources.

When does the federal solar tax credit end?

The Clean Energy Credit (previously called the federal solar tax credit, or ITC), is scheduled to end on January 1, 2035. Currently set at 30%, the credit will drop to 26% in 2033 and to 22% in 2034.

Can I receive 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 receive but generally yes, you can claim multiple types of incentives for your solar project. Get in touch with your solar installer or a local tax professional to ensure you are claiming all the incentives you qualify for and applying them in the correct order.

Can I receive any incentives when I add solar panels to a vacation home, rental property or commercial property?

While we recommend getting in touch with your local solar installer and/or tax professional to fully understand what solar incentives apply to you, many apply to a second home, so long as that home is in the United States and owned by you. There may be other incentives available for commercial properties specifically, depending on the specifics.
