Solar incentives are meant to encourage people to switch their home over to renewable energy by providing financial incentives that lower the burden of solar panel installation and use. Incentives could include things like discounts, cash back or credit towards your monthly utility bill. Some incentives are offered by the federal government, while others are offered by the Wisconsin government or your specific utility company, county or municipality. Categories of solar incentives include:

  • Tax Credits: These credits are dollar-for-dollar reductions (not deductions) in how much in taxes you owe the government.
  • Tax Exemptions: Tax exemptions may come in two forms. First, there is sales tax exemption, applied when you purchase solar panels. The second is property tax exemption. This allows you to ignore the value added by your solar system when paying property tax on your home.
  • Net Metering: Be sure to speak with your Janesville utility company about signing a net metering agreement. This allows you to get a credit towards your monthly utility bill for the value of excess energy generated by your solar panels. You could receive either a dollar-for-dollar credit or a percentage of the value.
  • Rebates: Rebates, or partial refunds after a purchase, are typically given before any solar tax credits are calculated. Rebates can be provided by your local utility company, by your state or by your county.

Federal Solar Incentives

When thinking about solar incentives, you likely think of federal incentives first. The solar incentive that you're most familiar with is probably the Federal Solar Investment Tax Credit (ITC), which provides a credit on your taxes equal to a specified percentage of the cost of your solar system.

The ITC can be applied to a solar system installed on your primary or secondary residence in the United States. The solar panels must have been installed on a property you own after January 1, 2006, for you to be eligible for the credit. Originally, the ITC covered 30% of all system costs (panels, labor, accessories and equipment), although the amount has fluctuated slightly over the last few years between 26-30%. The amount you qualify for will depend on when your solar system was installed. There is no cap on the amount you can claim.

Curious how the ITC might apply to your specific situation? Get in touch with your local Janesville solar panel installer to get more information.

In August 2022, the ITC (now called the Clean Energy Credit) was bolstered by the passing of the Inflation Reduction Act. With the new provisions, solar installation projects started after January 1, 2022, and completed by the end of 2032, may be eligible 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, the program expansion will also make it easier to get credit for energy storage systems.

State & Local Solar Incentives

Rebates, tax credits and more can be claimed at multiple levels. In addition to federal solar incentives, there are often state and local ones, too. These incentives may be distributed by the Wisconsin government, or by your county or municipality. Some incentives may be available for a limited time, while others are ongoing.

Next Steps for Installing Solar in Janesville

The nationwide use of solar energy has increased enormously in the last 15 years, in part thanks to the increase in availability of solar incentives. You may get these incentives from your local utility company, the Wisconsin government or the federal government. Reaching out to your local Janesville solar panel installer is an excellent first step towards making sure you get all the incentives you qualify for when you switch to solar energy.

EcoWatch's Janesville, WI Solar Incentives FAQs

How can I find out if I qualify for different solar incentives?

Generally, solar incentives apply to:

  1. a new solar system
  2. installed on property you own
  3. within the U.S.
  4. between the dates specified by a particular incentive.

Specific incentives, including those given out by the Wisconsin government or by your county/municipality, could have additional qualifications. Talk to your local Janesville solar installer to find out what incentives your project may 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 the 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 use both solar and another type of renewable energy to power my home?

You can power your home with multiple types of renewable energy, or a combination of renewable and non-renewable energy. Make sure you go over your ideas with your local Janesville solar installer. They can help you as you plan for your project and give you an understanding of various incentives that you may or may not qualify for.

What if I want to add solar panels to a rental property, vacation home or commercial property? Will I still qualify for incentives?

Many solar incentives apply to a property you own that is located within the United States; most secondary residences will fall into this category. There may be other solar incentives available for commercial properties, depending on the specifics. We recommend talking to your local solar installer and/or tax professional to best understand what incentives will apply to your specific situation.
