Environment calculator
Solar Panel Output Calculator
Estimate solar energy production from system size, sun hours, performance ratio, and days.
FormulaEnergy = system kW x sun hours x performance ratio x days
Formula
Solar output
Solar output depends on weather, shading, orientation, inverter losses, panel temperature, and local grid rules.
Energy = system kW x sun hours x performance ratio x days
A 5 kW system with 5 sun hours and 80% performance makes about 20 kWh per day.
