What could it save?

For an 800 W panel kit at Missouri's average residential price of 13.97¢/kWh (September 2025 – August 2026 (12 months)):

Ideal tilt (20°, south)
1,074 kWh a year: about $104 typical (69% used at home), up to $150 best case (100%)
Vertical railing (90°, south)
718 kWh a year: about $69 typical (69% used at home), up to $100 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 Jefferson City (capital). Try your own numbers · Is it worth it? · Railing vs tilted

Questions

Is plug-in solar legal in Missouri?

Missouri has no plug-in solar law. Without one, small plug-in systems fall under your utility's own interconnection rules. Ask your utility before you connect anything.
