A $200/month electricity bill in Oregon represents roughly 1,587 kWh per month at the state average rate of 12.6¢/kWh (EIA). With 4.5 peak sun hours per day, most Oregon homeowners need a 14.1 kW solar system — about 36 panels at 400W — to offset that usage. After the 30% federal ITC, net installed cost runs about $29,700, with 14.2-year simple payback and $57,800+ in estimated 25-year savings.
