The phrase "solar incentives" broadly refers to financial incentives designed to encourage the adoption and use renewable energy by making installing and using solar panels more affordable. You may be eligible for several kinds of incentives, including discounts, cash back or monthly utility bill credits, depending on your situation. Certain incentives come from your specific utility company, county or municipality, some from the state of Wisconsin and others from the federal government. Some solar incentives you might qualify for are:

  • Rebates: Solar rebates might be offered by your local utility company, or by your state or county. These rebates work as cash back that is applied after you purchase a solar system and before tax credits are calculated.
  • Tax Exemptions: These can come in the form of property tax exemptions, which let you exclude the value added by your solar panels when paying taxes on your house. You could also look for exemptions on sales tax at the time of purchase.
  • Net Metering: Net metering is an incentive you can get after your solar panels are up and running. If you've signed a net metering agreement with your Sun Prairie utility company, they will subtract the value of the excess energy your solar system produces from your utility bill each month. In some areas, this is a dollar-for-dollar credit, while in others you may receive a refund equivalent to a percentage of the value.
  • Tax Credits: Tax credits are dollar-for-dollar reductions (not deductions) in how much income tax you owe the federal government.

Federal Solar Incentives

When you hear the term "solar incentives," federal incentives are likely the first thing that comes to mind. A federal incentive many people are likely to be familiar with is the Federal Solar Investment Tax Credit (ITC). The ITC is a tax credit for a given percentage of your solar system's cost.

The ITC applies towards solar systems installed after January 1, 2006 and allows you to deduct from your taxes a percentage of the total cost of solar panels, accessories, equipment and labor. This credit can be claimed on a solar panel system installed on a primary or secondary residence that you own in the United States. The original claim amount was 30% of the total cost, although the amount you can claim may range between 26-30%. There is no maximum claim amount.

Contacting your local Sun Prairie solar panel installer is the best way to learn more about how the ITC applies to your situation.

The Inflation Reduction Act, passed in August 2022, expanded and extended the ITC (as well as renaming it to the Clean Energy Credit). The Clean Energy Credit re-raises the credit up to 30% for solar installation projects started after January 1, 2022 and completed by the end of 2032. After this, the credit percentage will be reduced slightly each year until the program expires in 2035. The expansion to the program also makes it easier to get credit for energy storage systems, starting in 2023.

State & Local Solar Incentives

Some solar incentives may be offered at the local or state level. As with federal incentives, these might include tax credits, rebates and more. The incentives — which may be provided by your county or municipality, or by the state of Wisconsin — may be offered for only a limited time, or on an ongoing basis.

Next Steps for Installing Solar in Sun Prairie

You can apply for solar incentives from the federal government and the Wisconsin government, as well as from your local utility company. This increase in availability of solar initiatives in the past 15 years has helped increase nationwide solar energy use enormously. If you're ready to make the change to solar energy, talking to your local Sun Prairie solar panel installation expert is a great first step.

EcoWatch's Sun Prairie, WI Solar Incentives FAQs

How do I learn if I qualify for different solar incentives?

In most cases, solar incentives apply to:

  1. a new solar panel system
  2. installed on a property that you own
  3. within the U.S.
  4. within the date range specified by a particular incentive.

Specific incentives, including those run by the Wisconsin government or by your county/municipality, could have additional qualifications. Speak with your local Sun Prairie solar installer to discover what incentives your project will qualify for.

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 you had your system installed between 2006 and 2021, you might qualify for a tax credit between 26% and 30%, depending on the date of installation. Speaking with the company that installed your solar system, or any local Sun Prairie solar installer, can help you learn what incentives you can apply for.

How much will solar panels save me on my electric bill in Sun Prairie annually?

After adding solar panels to your house in Sun Prairie, you can anticipate savings of approximately $1,091.48 per year, or approximately $20,738.09 over the next 20 years.

When does the federal solar tax credit end?

Get in touch with your solar installer or a local tax professional to make sure you are claiming all the incentives you are eligible for and applying them in the correct order.
