A $75/month electricity bill in Wyoming represents roughly 652 kWh per month at the state average rate of 11.5¢/kWh (EIA). With 5.0 peak sun hours per day, most Wyoming homeowners need a 5.2 kW solar system — about 14 panels at 400W — to offset that usage. After the 30% federal ITC, net installed cost runs about $11,000, with 14.0-year simple payback and $21,800+ in estimated 25-year savings.
