A $200/month electricity bill in Texas represents roughly 1,449 kWh per month at the state average rate of 13.8¢/kWh (EIA). With 5.6 peak sun hours per day, most Texas homeowners need a 10.4 kW solar system — about 26 panels at 400W — to offset that usage. After the 30% federal ITC, net installed cost runs about $21,800, with 10.4-year simple payback and $65,700+ in estimated 25-year savings.
How Many Solar Panels for a $200 Electric Bill in Texas?
