Cincinnati Considerations
Ohio Valley Climate
- Four seasons: Significant seasonal production variation
- Summer humidity: Minor efficiency impact on hot days
- Winter snow: Temporary production losses
- Spring/fall: Good shoulder season production
Cincinnati-Specific Factors
- Hilly terrain: Varied roof orientations due to topography
- Historic neighborhoods: Older roofs may need updates
- Tree coverage: Mature trees common in established areas
- Newer suburbs: Better suited for solar in many cases
Production Estimates
- Annual production: 1,200-1,350 kWh per kW installed

- Best months: May-August
- Winter production: 35-45% of peak
The Bottom Line
Cincinnati offers moderate solar economics with longer payback. Lower electricity rates and moderate sunshine mean 13-16 year payback periods, but property tax exemption and environmental benefits still make solar worthwhile.
Key points:
- 4.5 peak sun hours—moderate but viable for solar
- Lower Duke Energy rates (~$0.12/kWh) extend payback period
- Ohio property tax exemption is a meaningful benefit
- Environmental motivation often drives Cincinnati solar decisions
- Longer payback (13-16 years) but still worthwhile investment
