The term "solar incentives" refers to a range of financial incentives implemented to make installing and using solar panels more affordable. This is done to encourage people to switch to renewable energy. You might qualify for several kinds of incentives, including cash back, discounts or monthly utility bill credits, depending on your situation. Some incentives come from your specific utility company, county or municipality, some from the state of Iowa and others from the federal government. You might qualify for any of the following types of solar incentives:

  • 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 let you exclude the value added by your solar panels when you are calculating property taxes on your home.
  • Tax Credits: Different from tax deductions, tax credits reduce, dollar-for-dollar, the amount of income tax that you owe the government.
  • Rebates: Some solar companies will help you claim a rebate, or partial refund of your purchase, for your solar system. Counties or states will also sometimes offer limited-time rebates. Any rebates you receive will usually be deducted from the total price before tax credits are calculated.
  • Net Metering: Net metering becomes relevant after your solar system is up and running. If you've signed a net metering agreement with your Knoxville utility company, they will subtract the value of the excess energy your solar system produces from your utility bill each month. In some places, this is a dollar-for-dollar credit, while in other areas you might receive a refund equivalent to a percentage of the value.

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 probably familiar with is the Federal Solar Investment Tax Credit (ITC). This incentive is a tax credit for a predetermined percentage of the cost of your solar system.

The ITC applies to the total cost of installing a solar system, including the panels themselves as well as accessories, equipment and labor. This credit can be claimed for panels installed after January 1, 2006 on a primary or secondary residence located in the United States that you own. Originally set at 30% of total costs, the credit has fluctuated over time, and you may qualify for different amounts depending on when your project was completed. There is no maximum claim amount.

Speaking with your local Knoxville solar panel installer is the best way to learn more about how the ITC may apply to your situation.

In August 2022, the ITC (now referred to as the Clean Energy Credit) was bolstered by the passing of the Inflation Reduction Act. The new Clean Energy Credit is valid until 2035. You can now receive a 30% credit for solar systems that began installation on or after January 1, 2022 and will be done by December 31, 2032. The total credit will then decrease annually until it expires. Beginning in 2023, it will also be easier to obtain credits for energy storage systems with the new act.

State & Local Solar Incentives

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

Next Steps for Installing Solar in Knoxville

You can receive solar incentives from the federal government and the Iowa government, as well as from your local utility company.

EcoWatch's Knoxville, IA Solar Incentives FAQs

If my house already has solar panels, can I still claim incentives?

An excellent idea would be to talk to the company that installed your system — or call a local Knoxville solar installer — to learn about which incentives you might qualify for. If your system was installed after January 1, 2022, you likely qualify for the newly increased 30% tax credit under the Inflation Reduction Act. Systems installed between 2006 and 2021 may qualify for a tax credit of 26-30%.

What are the environmental benefits of switching to solar?

Solar energy is a renewable energy source — by changing where you get your energy, you can help reduce the strain on our planet's resources. A solar system can also lower the CO2 emissions from your home by 500 pounds a year, or roughly 13,000 pounds over 20 years.

When does the federal solar tax credit end?

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

I want to trade in my old appliances for ones that are more energy-efficient. Are there any benefits I can apply for?

The recently passed Inflation Reduction Act includes provisions for a number of incentives designed to reward homeowners who make eco-friendly upgrades. Some of these incentives include rebates and tax credits for installing new electric appliances. You can find more details about these incentives here.

Can I claim incentives both towards the initial cost of solar panels, and later as reimbursement?

Yes, you can receive both rebates and tax credits towards the cost of solar panels. Depending on which incentives you are applying for, they may apply in a different order. Make sure that you speak with your solar installer or a local tax professional to verify that you are claiming the correct incentives and that you're getting the most money possible.
