How is the yield of solar panels calculated?

How is the yield of solar panels calculated? The yield of solar panels is usually calculated in kilowatt hours (kWh) per year. This is calculated by taking into account the power of the solar panel (in kilowatts), the number of sun hours in the area and the efficiency of the solar panel.

The power of a solar panel is usually expressed in watts (W) or kilowatts (kW). The number of hours of sunshine depends on the location of the area and the season. For example, sunny areas may have more hours of sunshine than cloudier areas. The efficiency of the solar panel tells how efficiently the solar panel converts the sun’s radiation into electricity.

The yield of solar panels is calculated simply by multiplying the power of the solar panel by the number of sun hours and the efficiency of the solar panel. For example, if the power of the solar panel is 1 kW and there are 1000 hours of sunshine per year, and the efficiency of the solar panel is 20%, the output of the solar panel would be 1 kW * 1000 h * 0.20 = 200 kWh/year.
