PEAK SOLAR POTENTIAL AND SUN HOURS

Sun 3 kilowatts of solar energy
On average, a 3kW solar system generates between 12 to 15 units (kWh) per day under ideal conditions. The general formula for estimating daily power generation is: Solar System Size (kW) × Peak Sun Hours = Daily Energy Output (kWh) [pdf]
