After the full federal solar investment tax credit, the average cost to install a solar power system is $12,740 in Wisconsin, which is cheaper than in most states. The national average is $16,715. To make your new solar system even more affordable, you can get local solar incentives, including tax breaks and rebates, and there are low-interest loan programs.

Key insights

  • You can take advantage of solar tax breaks, rebates and loan programs in Wisconsin.
  • The average federal tax credit value is $5,460 in Wisconsin.
  • Wisconsin residents who install solar panels see an estimated savings of $21,005 over 25 years.

Solar incentives in Wisconsin

The federal solar investment tax credit (ITC) is the biggest factor in reducing the cost of going solar in Wisconsin. If you install a residential solar panel system by the end of 2032, you will receive a federal income tax credit equal to 30% of your system's total cost, including equipment, labor and permits.

The federal solar investment tax credit drops to 26% in 2033 and 22% in 2034.

For example, the average system in Wisconsin costs $18,200. At that price, you can get a $5,460 credit when you file your taxes.

The solar tax credit is not a rebate or refund — you must claim it when you file federal taxes in the year that your solar panel system becomes operational. To do this, you have to complete Form 5695. The credit is also nonrefundable, which means any unused portion rolls over into the next tax year.

Residential solar incentives in Wisconsin

Wisconsin doesn’t have as many solar incentives as other states, but it does have a few ways to save you some money when going solar:

  • Sales tax exemption: Eligible purchases of solar panels and other equipment are 100% exempt from sales and use tax.
  • Property tax incentive: This is an exemption for the value added to your home by a renewable energy system (solar, wind or synthetic gas).
  • Focus on Energy rebate program: Residents who invest in solar panels can get a rebate of up to $1,000. You can get $500 per solar energy system, with a bonus of $500 if you live in a rural area.
  • Milwaukee Shines loans: City of Milwaukee residents can sign up for a solar loan with a low interest rate through the Milwaukee Shines Solar Program. These loans are up to $20,000 with an interest rate of prime plus 1.5% to 2.25%.

What to know about net metering in Wisconsin

At times, your solar system can produce more energy than you need. You can store this extra energy with solar batteries or sell it to your local power company. Selling your power to electric companies is called net metering.

In Wisconsin, compensation for net metering is a credit on your next month’s electricity bill. If your net excess generation (NEG) exceeds $25, the company must write you a check.

How can I pay for solar panels?

You can pay cash, but most people finance solar panels. A solar loan works a lot like any other type of loan — there’s an application and approval process, and you pay it back over time (with interest). If you are considering taking out a solar loan or entering a solar lease or power purchase agreement (PPA), always ask:

  • Is there a down payment?
  • How much will I pay per month?
  • Will monthly payments increase, and by how much?
