Understanding Solar Irradiance: Measurement, Calculation, and
Measurement of Solar Irradiance. Solar irradiance is generally measured in watts per square meter (W/m²). This unit of measurement allows for a clear understanding of how much solar power is being received per square meter of a given surface area. The higher the irradiance level, the more solar power available to be converted into electricity.
