What makes Columbia different
Columbia (population ~129,330) gets 4.42 peak sun hours per day — that's 8% less sunny than the Missouri average of 4.8. Slightly less local sunlight means panels produce a touch less than the state average, so sizing and orientation matter. Electricity rates, net metering, and incentives are set at the Missouri level: residents pay about 13¢/kWh, and full net metering + utility rebates ($0.25–0.50/w).
