Average system payback period

Solar power in Wisconsin on rooftops is estimated to be able to provide 40.1% of the electricity used in Wisconsin, using 23,600 MW of solar panels. Net metering is available for systems up to at least 20 kW, and excess generation is credited at retail rate to customers next bill. Some utilities allow net metering up to 100 kW. For Xcel customers, kilowatt credits are rolled over monthly and are reconciled annually at avoided cost. Best practices recommend no limits, either individually or aggregate, and perpetual roll over of kilowatt credits.

A 2016 estimate indicates that a typical 5 kW solar array installed in Wisconsin will pay for itself in 13 years and go on to provide an additional profit of $18,860 during its 25-year life. Wisconsin's renewable portfolio standard requires 10% renewable sources for electricity by 2015.

I am claiming the 26% Federal Tax Credit (ends 2022) i

When you install a solar system, 26% of your project expenses apply toward a credit to offset any taxes you owe that year. This federal tax credit is a major incentive to go solar, but it is going to be phased out by 2024.

To be eligible to claim this credit, you must owe federal taxes.
