The average cost to install solar on a home in Wisconsin is $3.57 per watt, with about 80 percent of systems installed for $2.47 per watt to $4.57 per watt. This is higher than the average solar cost in the East North Central Region of $3.33 per watt.
The average size of a solar system in Wisconsin is 5.8 kilowatts, which would cost around $20,700 without any federal, state, or local incentives.
1 kilowatt of solar PV in Wisconsin produces an average of 1,300 kilowatt-hours of electricity per year, so a 5.8 kilowatt solar system would generate 7,541 kilowatt-hours of electricity every year. An average household in Wisconsin uses 8,014 kilowatt-hours of electricity in a year.
With an average state electricity price of 15 cents per kilowatt-hour, this solar system could save a household in Wisconsin $1,114 each year. At this rate of annual savings, the system could pay for itself in about 19 years assuming no additional system expenses. This is less than the expected 30-year lifespan of a typical solar panel.
