Cost of Solar Panels in Wisconsin

The average cost of solar panels in Wisconsin is $2.60 per watt, which is below the national average of $2.66 per watt. Using this figure, in Wisconsin, a typical 7-kilowatt solar system would cost $13,468 after claiming the 26% federal solar tax credit.

Keep in mind that these figures are only estimates, and the price of installing solar photovoltaic (PV) systems for your home may look quite different based on factors unique to you. We recommend getting at least three quotes and comparing them to find the best installer for your needs and budget.

Solar Panel System Installation Cost in Wisconsin

Depending on the size of your solar energy system and the company you choose, we’ve estimated that a solar panel installation in Wisconsin would cost between $10,400 and $26,000 before applying any tax incentives or solar rebates.

To offset the average Wisconsin energy bill of about $100 per month, you’d need a 7-kW solar panel system, which costs roughly $18,200, or $13,468 after the federal solar tax credit.

We’ve included the average prices for solar panel systems in Wisconsin before and after the tax credit in the table below:

Size of Solar Panel System Wisconsin Solar Panel Cost Cost After Federal Tax Credit
4 kW $10,400 $7,696
5 kW $13,000 $9,620
6 kW $15,600 $11,544
7 kW $18,200 $13,468
8 kW $20,800 $15,392
9 kW $23,400 $17,316
10 kW $26,000 $19,240

What Determines the Cost of Solar Panels in Wisconsin?

Besides system size, there are a number of factors that go into determining solar panel costs in Wisconsin. We explain the main ones below.

Solar Equipment

The size and type of solar equipment needed will play the biggest role in determining how much solar panel installation costs in Wisconsin. For instance, a 5-kW system will cost you less than $10,000 after applying the federal tax credit, while a 10-kW system will be closer to $20,000.

The average Wisconsin resident going solar will install a 7-kW PV system, but the size that’s right for your home depends on your specific energy needs. You can get a rough idea of how many solar panels you’ll need based on your past utility bills, available roof space and the amount of sunlight your home gets. However, the only way to truly determine what solar energy system size you need is to get a personal assessment from a reputable solar company.

It’s not only the size but the type of solar panels you’ll need that will determine the cost of your solar panel installation. There are three popular types of solar panels on the market — monocrystalline, polycrystalline and thin-film — and each comes at a different cost. But you may have to choose one type of solar panel over the others based on the layout of your Wisconsin home.

For instance, if you have a smaller roof, you may need more efficient solar panels due to a lack of space. Monocrystalline puts out the highest efficiency (more kilowatt-hours per square foot covered), and because of that, they’re more expensive than polycrystalline and thin-film solar panels. While you’ll have to pay more upfront for monocrystalline solar panels, having higher efficiency panels will have a bigger benefit — and savings — in the long run.

In addition to solar panels and inverters, you’ll also need to consider if you want any add-on equipment, like a battery or an EV charger. These will raise the upfront costs of your solar system.

Solar Financing

Solar financing companies offer loans that will play into your overall costs and how long you’ll have to pay off your solar panels. If you get a solar loan with a high interest rate, your total costs will be higher. Similarly, if you pay more, or all, of the cost of your solar panel installation up front, you’ll pay less interest on the back end. We recommend making as high an initial purchase as you can to maximize your savings.

Solar Installation Company

The good news is there are a lot of solar companies that service Wisconsin, so companies may try to undercut one another by offering sales, discounts and overall lower prices. Don’t be afraid to shop around different companies to find one that’s going to offer the best solar installation option for your home.

Wisconsin Solar Incentives

Aside from dairy, Wisconsin is perhaps best known for its harsh winters. That may have some people wondering if it’s worth going solar in Wisconsin. However, there are already thousands of Wisconsin residents saving money and reducing their carbon footprint by turning to renewable energy alternatives. And did you know that solar panels are actually more effective in colder conditions?

To encourage the adoption of clean energy sources, federal, state and local governments have implemented financial incentives for going solar. Here are the highlights:

Wisconsin Solar Incentive How it Affects the Cost of Solar Panels in Wisconsin
Property Tax Exemption Installing solar will increase the value of your home, but Wisconsin has laws in place to ensure your property taxes don’t rise due to your clean energy addition.
Sales Tax Exemption In Wisconsin, solar equipment is exempt from the state’s 5% sales tax.
Focus on Energy This statewide solar program offers up to a $500 rebate for qualified home solar installations.
Net Metering Wisconsin requires all utilities to have net metering programs for customers that generate electricity through systems up to 20 kilowatts. This means that you can “sell” your excess electricity back to your power company. (Learn more)
Local Solar Rebates & Incentives Make sure to look up any additional rebates or credits available in your area. For example, the City of Milwaukee offers low-interest loans for homeowners wanting to install solar through its Milwaukee Shines solar energy program.
Federal Solar Tax Credit When you install solar panels on your Wisconsin home, you become eligible for the solar investment tax credit (ITC) — also known as the federal solar tax credit. It’s currently worth 26% of your installed system costs, but it’s set to reduce to 22% in 2023 and be eliminated for residential solar in 2024.

Best Solar Panel Brands and Installed Solar System Costs in 2022

Whether you’re installing a DIY solar panel system or having one of the best solar companies in Wisconsin handle the details, you’ll want to choose the best solar panels for your home. So, how much will the panels themselves set you back?

Here’s a price comparison of the best solar panel brands on the market:

Solar Panel Brand Average Cost Per Watt ($-$$$$$)

JA Solar $$
Mission Solar $$
