In 2023, Wisconsin had over 1.2GW of solar energy, enough to power over 200,000 homes. The Badger State is steadily increasing its renewable infrastructure, which is good news for homeowners. Those who install a 6kW system could save as much as 15,000 or more with solar panels in Wisconsin.
You may consider installing an array of your own, but where do you start? In this article, we cover the essentials; from average prices to potential savings, we explain it all. Let’s get into it.
Average Cost of Solar Panels in Wisconsin
Homeowners can find a pretty good deal on solar panels in Wisconsin. At a rate of about $2.60 per watt, equipment ranges just slightly higher than in most states. Wisconsinites purchasing a 6kW system could expect to spend around $15,600 before incentives.
This isn’t too bad, and the value of an array increases when considering the traditional electricity rate in the Badger State. Wisconsinites use some of the least amount of power in the country, just under 700kWh. Even with the high rate of electricity, residents have low utility bills. This means that while offsets may not be exorbitant, systems won’t cost as much.
If this gets you excited about solar panels in Wisconsin, the federal solar tax return can jumpstart your installation. Offering a 30% credit on all purchases made toward an array, homeowners who install a 6kW system could see their initial investment drop from $15,600 to $10,920.
How Much Solar Do Wisconsinites Need?
The example above breaks down the average price of solar panels in Wisconsin as it relates to the typical solar panel system. However, with fewer power requirements than most, homeowners could get away with smaller arrays, saving money on installation costs.
To find the right size system for your household, take your typical daily power usage and divide it by the amount of direct sunlight you receive per day. We’ll use Wisconsin’s standards to show you how this works.
Homeowners in the Badger State use about 23.1kWh a day (or 694kWh a month). When we divide that by Wisconsin’s average peak sun of 4.29 hours, we learn that a solar panel system needs to produce 5.4kW an hour to meet power needs. Slightly smaller than normal, Wisconsinites would only have to spend $14,040 for this size array.
Now that you know how to find the right wattage for your home, you can plan out a more accurate budget. And because sunlight varies depending on location, you can use this Wisconsin sun chart to find the average for your hometown.
Wisconsin Solar Cost Factors
As we saw above, sunlight plays a role in determining the price of solar panels in Wisconsin. Covering a wide range from north to south, homeowners in the Badget State might find more exposure as they move further from the Canadian border. For example, homeowners in Milwaukee could receive about 4.5 hours of direct sunlight, about 15 minutes more than in most places across the state.
To see how peak sun and location can affect solar prices even further, compare Wisconsin to the states surrounding it:
You’ll also find that solar panel type can affect the cost of your home array. Generally, you’ll choose between monocrystalline for efficiency and polycrystalline for affordability. Considering the Badger State’s average sunlight and heavy winters, you’ll want a panel that can provide the most electricity.
Finally, you want to take serious time to choose your solar installer. While you may try to save money on labor, some companies try to offer better rates by cutting equipment quality or warranty coverage. With over 80 installers in Wisconsin, you have plenty of options to choose from.

Can Solar Energy Save Wisconsinites Money?
With decent rates on equipment and high electricity rates, homeowners can seriously consider solar panels in Wisconsin. Even with average sunlight and low power needs, Wisconsinites can save thousands on utilities over 25 years. Let’s take a look at how much you could see in returns.
First, you’ll have to pay off your system. Suppose we use the average annual utility bill in Wisconsin to cover the cost of an installation. At about $1,255.08 a year, homeowners could pay off a 6kW system in about 12.4 years. While this is longer than usual, it’s worth considering that some Wisconsinites may not need that much wattage to cover their power needs.
After paying off a solar array, residents start to see net returns on their utilities. Solar panels in Wisconsin have a lifespan of about 20-25 years, meaning you could save around $9,539 to $15,312. And with federal and state incentives, those numbers can rise even further.
Solar Panels in Wisconsin: Rebates, Credits, and Incentives
Wisconsin may seem like a sleeper state for solar panels, but it actually has pretty solid programs for home solar. Homeowners have access to regulations such as equipment rebates, net metering, and tax exemptions. When used alongside the federal solar tax credit, which can save homeowners over $4,500 on an installation, solar panels become incredibly affordable.
