A $150/month electricity bill in Vermont represents roughly 735 kWh per month at the state average rate of 20.4¢/kWh (EIA). With 4.1 peak sun hours per day, most Vermont homeowners need a 7.2 kW solar system — about 18 panels at 400W — to offset that usage. After the 30% federal ITC, net installed cost runs about $15,100, with 9.6-year simple payback and $50,500+ in estimated 25-year savings.
How Many Solar Panels for a $150 Electric Bill in Vermont?
