The phrase "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. Incentives could include things like discounts, cash back or credit on your utility bill each month. Some incentives are provided by the federal government, while others are handled by the state of Wisconsin or your utility company, county or municipality. Categories of solar incentives include:

  • Net Metering: Net metering is an incentive you can get once your solar panels are up and running. If you have a net metering agreement with your Mequon utility company, the company will subtract the value of the excess energy your solar system produces from your utility bill each month. In some places, this credit is dollar-for-dollar, while in others you might receive a refund equivalent to a percentage of the value.
  • Tax Credits: Unlike tax deductions, tax credits are dollar-for-dollar reductions in the amount of income tax that you owe the federal government.
  • Tax Exemptions: Your solar panel system may qualify for exemptions on both sales and property tax. Sales tax exemptions come into effect at the time of purchase. Property tax exemptions let you exclude the value that solar panels add when calculating property taxes on your home.
  • Rebates: Some solar companies will help you claim a rebate, or partial refund of your purchase, for your solar panels. States or counties will also sometimes offer limited-time rebates. The value of a rebate will usually come off your total price before any tax credits are calculated.

Federal Solar Incentives

Federal solar incentives are likely the first thing that you think of when you think about solar incentives. You've likely heard of the Federal Solar Investment Tax Credit, or ITC. This is a tax credit that reduces your taxes by a certain percentage of the money you spend installing solar panels.

The ITC can be applied to solar systems installed after January 1, 2006, on a primary or secondary residence that you own in the United States. Initially, the credit applied to 30% of the total cost – for panels, equipment, accessories and labor – although that amount may range from 26-30%, depending on the installation date of your solar system. There is no cap on the amount you can claim.

To more fully understand how the ITC could apply to you, contact your local Mequon solar panel installation expert and ask for more information.

In August 2022, the ITC (now called the Clean Energy Credit) was bolstered by the passing of the Inflation Reduction Act. Under the new program, solar installation projects begun after January 1, 2022, and finished by December 31, 2032, can qualify for a 30% tax credit. The amount of the credit will then decrease slightly each year until the end of the current Clean Energy Credit in 2035. Beginning in 2023, it will also be easier to claim credits for energy storage systems under this new program.

State & Local Solar Incentives

There are more than just federal solar incentives; tax credits, rebates and more are often offered at the state and local level. Certain incentives are ongoing, while others are available for a limited time. Incentives may be offered by the Wisconsin government, or by your county or municipality.
