A $50/month electricity bill in Virginia represents roughly 360 kWh per month at the state average rate of 13.9¢/kWh (EIA). With 4.7 peak sun hours per day, most Virginia homeowners need a 3.1 kW solar system — about 8 panels at 400W — to offset that usage. After the 30% federal ITC, net installed cost runs about $6,400, with 12.3-year simple payback and $15,400+ in estimated 25-year savings.
