Solar Energy System Sizing Calculation Formula
The Solar Energy System Sizing calculation formula is the key to determining the right size of your solar energy system. Here’s the formula:
Solar Energy System Size = (Total Daily Energy Consumption x Days of Autonomy x Inverter Efficiency x Temperature Derating Factor) / (Peak Sun Hours x Solar Panel Efficiency)
The formula requires you to input certain parameters such as your Total Daily Energy Consumption, Days of Autonomy, Inverter Efficiency, Temperature Derating Factor, Peak Sun Hours, and Solar Panel Efficiency.
Categories / Types / Range / Levels of Solar Energy System Sizing
Solar Energy System Sizing can vary depending on the size of your home or business. Here are the different categories/types/levels and their recommended ranges expressed in kilowatts (kW):
| Category | Range |
|---|---|
| Tiny Home | 1-5 kW |
| Small Family Home | 5-10 kW |
| Large Family Home | 10-20 kW |
| Small Business | 20-50 kW |
| Large Business | 50-100 kW |
| Industrial | 100+ kW |
The recommended range varies depending on the size of your home or business. For example, a Tiny Home requires a solar energy system size of 1-5 kW while an Industrial setup requires a solar energy system size of 100+ kW.
