Solar incentives mitigate the cost of installing solar panels on your home. These financial incentives are intended to encourage more homeowners to convert their home partially or fully to renewable energy. Incentives could include things like discounts, cash back or monthly utility bill credits. Some incentives are offered by the federal government, while others are provided by the state of Iowa or by your utility company, county or municipality. Some broad categories of solar incentives include:

  • Net Metering: You can sign a net metering contract with your Dubuque utility company, that may apply to all or a percentage of the excess electricity that is generated by your solar panels. Your utility company will then subtract this value from your utility bill each month.
  • Rebates: A rebate is a partial refund given after you've purchased your solar panels. Rebates could be offered by your local utility company, your state or your county. The rebates are usually applied before tax credits are calculated.
  • Tax Exemptions: Sales tax exemptions go into effect at the point of sale for your solar panels. Property tax exemptions allow you to exclude the value that your solar panels add when you're calculating how much property tax you need to pay on your house.
  • Tax Credits: Tax credits reduce, dollar-for-dollar, how much income tax you owe the federal government. Tax credits differ from tax deductions.

Federal Solar Incentives

When you think about 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 provides a credit on your taxes equal to a certain percentage of the cost of your solar system.

The ITC applies to solar panels installed on your primary or secondary residence in the United States. The solar system must have been installed on a property you own after January 1, 2006, for you to be eligible for the credit. The ITC initially covered 30% of all system installation costs (panels, equipment, accessories and labor), although this amount has fluctuated over the last few years between 26-30%. The installation date of your solar system will determine what percentage you are eligible for. There is no cap on the claim amount.

Your local Dubuque solar panel installation expert can provide 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). With the new provisions, solar installation projects begun after January 1, 2022, and finished by December 31, 2032, might qualify for a 30% tax credit. This percentage will then decrease slightly each year until the end of the current Clean Energy Credit in 2035. Starting in 2023, it will also be easier to claim credits for energy storage systems with the new act.

More information about the new Inflation Reduction Act can be found here. The easiest way to understand how the new Clean Energy Credit might apply to you is to speak with your local Dubuque solar panel installation expert directly.

State & Local Solar Incentives

Federal solar incentives are not your only option; rebates, tax credits and more may be offered at the state and local level. Incentives may be offered 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 Dubuque

The large number of available solar incentives has contributed greatly to the increase in the use of solar power nationwide over the past 15 years. You can get solar incentives from your local utility company, the Iowa government or the federal government. Reaching out to your local Dubuque solar panel installer is the right first step towards getting all the incentives you qualify for when you switch to solar energy.

EcoWatch's Dubuque, IA Solar Incentives FAQs

If I already have solar panels, can I still claim incentives?

If your solar system was installed after January 1, 2022, you may qualify for the recently increased 30% tax credit under the Inflation Reduction Act. If your system was installed between 2006 and 2021, you may qualify for a tax credit between 26% and 30%, depending on the exact installation date. Reaching out to the company that installed your solar system, or any local Dubuque solar installer, can help you understand what incentives you qualify for.

How long until the federal solar tax credit ends?

The Clean Energy Credit (previously referred to as the federal solar tax credit, or ITC), is slated 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 initial cost of solar panels, and later as reimbursement?

The order that incentives will be applied in may vary depending on which incentives you are eligible for but usually yes, you can receive multiple types of incentives for your solar project. Check with your solar installer or a local tax professional to ensure you are claiming all the incentives you're eligible for and applying them in the correct order.
