Digital Solar Power Meter

A pyranometer is a light sensor made of silicon that measures the power per area incident on the sensor. … This measurement is known as the solar irradiance” a measurement of power (rate of energy) per unit area”. The pyranometer may be considered as solar power meter, as the link below shows.
