What could it save?
For an 800 W panel kit at Wyoming's average residential price of 14.01¢/kWh (September 2025 – August 2026 (12 months)):
- Ideal tilt (20°, south)
- 1,228 kWh a year: about $119 typical (69% used at home), up to $172 best case (100%)
- Vertical railing (90°, south)
- 885 kWh a year: about $86 typical (69% used at home), up to $124 best case (100%)
"Typical" uses HTW Berlin's model for an 800 W system without a battery; exports are assumed to earn nothing. Solar data: NREL PVWatts for Cheyenne (capital). Try your own numbers · Is it worth it? · Railing vs tilted
