How it is calculated

The system is sized to cover 100% of your yearly use with your state’s solar production (NREL PVWatts). Cost = system watts × the average installed price per watt in your state from EnergySage (2026), or the U.S. average of $2.60/W where no state figure is available.

Yearly savings = the electricity the system produces × your state’s average residential rate (EIA, March 2026). Simple payback = cost ÷ yearly savings. It assumes full credit for every kWh (net metering) and ignores panel degradation and future rate changes.
