How to calculate the total power of the solar panel

Simple Calculation of Photovoltaic Systems

The photovoltaic system includes photovoltaic modules, batteries, mains input, inverters, and controllers.

The theoretical calculation method of the system can be simply referred to as follows: the load determines the power of the inverter; The inverter power determines the battery capacity; The battery capacity determines the size of the solar panel

For example, for a 3.2kw inverter, a battery capacity of 4.8KWH is required in a ratio of 1.5.

3.2KW*1.5=4.8KWH; The battery capacity should be 4.8KWH

The solar panel generates electricity for 5 hours of sunlight per day, which is calculated as 4.8kwh/0.8c/5h=1.2kw.

0.8C refers to the conversion efficiency of solar panels

1.2KW is the total power of the solar panel. This way, you can choose solar panels.

When the local sunshine time of the customer is relatively long, the total power of our solar panels can be reduced a bit.

If the local sunshine time of the customer is short, the total power of our solar panels needs to be increased.
