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.

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.
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.
