A $50/month electricity bill in Colorado represents roughly 352 kWh per month at the state average rate of 14.2¢/kWh (EIA). With 5.5 peak sun hours per day, most Colorado homeowners need a 2.6 kW solar system — about 7 panels at 400W — to offset that usage. After the 30% federal ITC, net installed cost runs about $5,400, with 10.3-year simple payback and $16,500+ in estimated 25-year savings.
How Many Solar Panels for a $50 Electric Bill in Colorado?
