- Higher electricity rates: ~$0.14/kWh through We Energies
- Focus on Energy: State rebates for solar installations
- Cold climate benefit: Panels work better in cold weather
- Net metering: Good policies through We Energies

*Focus on Energy rebate amounts vary—check current program. No federal credit for purchased systems.
Production & Savings
- Annual production: 1,150-1,300 kWh per kW installed
- 7 kW system output: ~8,000-9,100 kWh/year
- Annual savings: $1,100-1,350 at $0.14/kWh
- Payback period: 12-15 years (with Focus on Energy rebate)
Seasonal Production Pattern
- Peak months: May-July (long days, good sun)
- Shoulder months: March-April, August-September
- Winter low: November-February (shorter days, clouds)
- Snow impact: Minimal—panels usually self-clear
The Bottom Line
Milwaukee solar is better than you'd expect. Focus on Energy rebates, higher electricity rates, and cold weather efficiency mean paybacks of 12-15 years are achievable—not bad for a northern city.
Key considerations:
- Focus on Energy rebates are crucial—apply early
- Higher electricity rates help offset lower sunshine
- Cold weather actually improves panel efficiency
- PPA/Lease option retains federal credit benefit
- Wisconsin property and sales tax exemptions help
- Size system for annual usage, not just summer peak
