Estimate daily energy production for a solar array based on wattage and sun hours. Helps homeowners and installers predict system performance.
Peak Sun Hours are not just daylight hours. They represent the equivalent number of hours where solar intensity is 1000 W/m². Cloudy days have fewer peak sun hours.
This tool assumes ~20% system loss for wiring, inverter inefficiency, dust, and temperature heat derating.
Include system loss (~20%).
