Solar Production in Houston
Houston receives 4.9 peak sun hours per day. This is the key input that determines how much electricity your panels produce. More sun hours mean more kWh generated, which translates directly to a lower bill.
Production estimates use a 7kW system at 80% efficiency (accounting for inverter losses, shading, and temperature derating). Actual output depends on roof orientation, tilt, and shading.
