What an 800W kit would do in South Carolina
Assuming ~4.8 peak sun hours per day and typical system losses, a standard two-panel 800W plug-in kit in South Carolina produces about 1079 kWh per year. At the state’s average residential rate of 14.3¢/kWh, that’s roughly $131 per year off your electric bill if you self-consume most of it. A typical 800W kit costs $500–$1,200, so simple payback lands in the 5–9 year range. Run your own numbers →
