Quick Guide to Use Solar PV Size Calculator
- Enter your monthly energy consumption in kilowatt-hours (kWh).
- Input the average peak sun hours per day for your location.
- Provide the derate factor (a decimal value representing system losses, also called solar panel efficiency).
- Click the “Calculate” button to determine the recommended Solar PV Size in kW.
- Use the “Reset” button to clear the fields and start a new calculation.
Formula
Solar PV size in kW = Daily energy consumptions in kWh / (peak sun hours per day X derate factor in decimals)
Where, daily energy consumption = monthly energy consumption kWh/ 30days
