Wisconsin solar calculator
Live production from NLR (formerly NREL) PVWatts V8. Wisconsin's main state incentive is the Focus on Energy rebate — $600/kW upfront, capped at $2,400 (NOT a tax credit; a cash rebate paid after install, reducing your installed cost directly). Net metering is set PER UTILITY: this calculator models the 1:1 retail-match case for a properly-sized residential system on We Energies (largest IOU); MG&E, Alliant/WPL, and WPS are similar. KEY: don't oversize — We Energies pays only ~$0.042/kWh on monthly excess vs ~$0.19 retail. Size to ~100% of your annual use. Wisconsin has NO state income tax credit. Sales tax and property tax both exempt. Defaults: south-facing roof mount, 20° tilt, 14% losses.
Try (Milwaukee), (Madison), (Green Bay) — any valid US ZIP for this state also works.
