Wisconsin solar notes
Wisconsin requires net metering only up to 20 kW and terms vary by utility, but Focus on Energy offers statewide cash-back rewards for new residential systems.
Heads up: the 30% federal tax credit for purchased home solar ended Dec 31, 2025. Leased/PPA systems may still qualify through 2027, and Wisconsin may offer its own incentives — check locally.
