The term "solar incentives" includes a range of financial incentives designed to make installing and using solar panels more affordable. This is done to encourage people to switch to renewable energy. You might be eligible for various kinds of incentives, such as discounts, cash back 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 Wisconsin and others from the federal government. Categories of solar incentives include:

  • Tax Credits: Tax credits are dollar-for-dollar reductions (not deductions) in how much in taxes you owe the government.
  • Rebates: Rebates, or cash back after a purchase, are normally given before any solar tax credits are calculated. Solar rebates may be provided by your local utility company, by your state or by your county.
  • Net Metering: Net metering factors in once your solar system is up and running. If you have in place a net metering agreement with your Madison utility company, it will subtract the value of the excess energy produced by your solar system from your utility bill each month. In some areas, this credit is dollar-for-dollar, while in other places you might make back a percentage of the value.
  • Tax Exemptions: These could come in the form of property tax exemptions, which can let you exclude the value of your solar system when calculating the taxes you pay on your home. You could also look for exemptions on sales tax at the time of purchase.

Federal Solar Incentives

Federal solar incentives are likely to be the first thing that you think of when you think about solar incentives. 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 your solar system's cost.

The ITC applies to solar systems installed after January 1, 2006, on a primary or secondary residence in the United States that you own. The credit initially covered 30% of the total cost – for panels, equipment, accessories and labor – although that amount may range from 26-30%, depending on when your solar project was undertaken. There is no cap on the claim amount.

To more fully understand how the ITC could apply to you, contact your local Madison solar panel installer and request more information.

The Inflation Reduction Act, passed in August 2022, made some changes to the ITC (as well as renaming it to the Clean Energy Credit). Now, solar installation projects begun after January 1, 2022, and finished by December 31, 2032, may be eligible for a 30% tax credit. The amount of the credit will then see a slight annual decrease until the current Clean Energy Credit expires in 2035. The expansion to the program also makes credits for energy storage systems even easier to claim, starting in 2023.

State & Local Solar Incentives

Some solar incentives may be provided at the state and local level. Like with federal incentives, these might include rebates, tax credits and more. These incentives might be offered by the Wisconsin government, or by your county or municipality. Certain incentives are ongoing, while others are available for a limited time.
