Solar incentives are intended to make renewable energy usage more affordable via financial incentives to help people install solar panels on their homes. Various kinds of incentives, including discounts, cash back or monthly utility bill credits, may be available to you. Certain incentives may be provided via the Wisconsin government, by your utility company or by county or municipality, while other incentives are federal. Some solar incentives you might qualify for are:

  • Rebates: Some solar companies will help you claim a rebate, or partial refund after purchase, for your solar panels. Counties or states will also offer limited-time rebates at various times. Any rebates you receive will usually be deducted from your total price before any tax credits are calculated.
  • Tax Exemptions: These could come in the form of property tax exemptions, which let you ignore the value added by your solar panels when paying taxes on your house. They may also include exemptions on sales tax at the time of purchase.
  • Tax Credits: Tax credits are dollar-for-dollar reductions (not deductions) in how much income tax you owe the federal government.
  • Net Metering: Be sure to talk to your DeForest utility company about signing a net metering agreement. This will allow you to receive credit towards your monthly utility bill for the value of excess energy your solar panels generate. You might receive either a dollar-for-dollar credit or a percentage of the value.

Federal Solar Incentives

When thinking about solar incentives, federal incentives are likely the first thing that comes to mind. The Federal Solar Investment Tax Credit, or ITC, is the most well-known federal solar incentive. The ITC offers a tax credit for a predetermined percentage of your solar system's cost.

The ITC can be applied to solar systems installed after January 1, 2006, and lets you deduct from your taxes a percentage of the total cost of solar panels, equipment, accessories and labor. You can receive this credit for a solar panel system installed on a primary or secondary residence in the United States that you own. The original claim amount was 30% of the total cost, although certain projects may qualify for only 26%, depending on the details. There is no maximum claim amount.

Your local DeForest solar panel installation expert can offer more information about the ITC and how it may apply to your situation.

In August 2022, the Inflation Reduction Act made revisions to the ITC, now titled the Clean Energy Credit. With the new provisions, solar installation projects that are completed between 2022 and 2032, may be eligible for a 30% tax credit. This credit amount will then decrease slightly each year until the current Clean Energy Credit expires in 2035. Starting in 2023, the expansion will also make credits for energy storage systems even easier to claim.

More information about the new Inflation Reduction Act can be found here. Your local DeForest solar panel installer can answer any questions you have and explain how the new Clean Energy Credit applies to you.

State & Local Solar Incentives

Some solar incentives are often also offered at the local or state level. As with federal incentives, these might include tax credits, rebates and more. Some incentives are ongoing, while others are offered for only a limited time. Local solar incentives might come from the Wisconsin government, or from your specific county or municipality.
