Solar panels offer many benefits, but the best thing about solar power is its renewable nature. Solar energy can be used in any part of the globe without causing harm to the environment. The primary reason for switching to clean energy sources is its ability to reduce the energy cost. The long-term savings are significant and solar panels have a low maintenance cost. There are many uses for solar energy. You can use solar energy to generate electricity even in remote areas, or to extract water from regions that have limited water resources. SunVest's knowledge and experience with state and federal incentive programs as well as local contractor regulations adds an additional value to design-build. That knowledge is put to use for your benefit. This is why SunVest has been consistently recognized by Solar Power World magazine as a leader in the solar industry and our customers.

How this Madison solar cost calculator works

This calculator sizes a solar system from your electricity use. Your monthly bill, divided by the average Wisconsin electricity price, gives your yearly use; Wisconsin's sunshine (1,334 kWh per kW of panels a year) then gives the system size that covers it, adjusted for roof direction and shade. The installed price is that size multiplied by the price per watt homeowners in Wisconsin pay installers. Payback compares that price with what the panels save at Wisconsin power prices, assuming prices rise 3% a year.

Wisconsin numbers this calculator uses

Installed price
$2.59–$3.51 per watt in Wisconsin (typical $3.05), before rebates. A typical 6 kW home system costs $15,500–$21,100.
Sunshine
1,334 kWh of electricity per kW of panels a year in Wisconsin.
Electricity price
About 19¢ per kWh, the average residential price in Wisconsin.
Selling power back
Full retail net metering: power you send to the grid earns a credit at about the price you pay for it.
Rebates and tax credits
The 30% federal tax credit for buying solar ended for systems installed after December 31, 2025. Leases and power purchase agreements can still carry a federal credit through the installer for systems in service by the end of 2027.

An estimate, not a quote. Roof size and pitch, shading, equipment, permits and the installer all change the final price; installers confirm it after a site visit. Sources: EnergySage state installed-cost data (2026), NREL PVWatts, U.S. Energy Information Administration residential prices (2026), state program pages.

Frequently asked questions

7 questions
How many solar panels do I need for my home in Wisconsin?
The calculator estimates system size based on your power bill, roof direction, and other factors. A typical 6 kW system might need about 18 panels.
Are solar panels worth it in Wisconsin?
With electricity at 19 cents per kWh and full retail net metering, solar can reduce bills significantly. Payback varies by system size and usage.
Can I sell power back to the grid in Madison?
Yes, Wisconsin offers full retail net metering, where power sent to the grid earns a credit at the same rate you pay.
What tax credits are available for solar in 2026?
The 30% federal tax credit ended for purchases after 2025. Leases and PPAs may still qualify for federal credits through 2027.
Does roof direction affect solar panel efficiency?
Yes, south-facing roofs need fewer panels. East or west roofs need about 15% more. North-facing roofs are usually not viable.
How does shade impact solar panel output?
Heavy shade significantly reduces solar output. The calculator considers shade when estimating system size and cost.
How much more electricity do electric cars use?
Each electric car charged at home adds roughly 2,700 kWh a year, equivalent to about 15,000 km of driving.
