Use Second Class Pyranometers, First Class Pyranometers or Secondary Standard Pyranometers as per your requirements. Analog or digital signal output models are available.
Global irradiance is the amount of radiant energy (electromagnetic radiation from the sun) on a flat surface. It’s important to measure irradiance to know how much power a solar project could potentially harvest from the Sun. The irradiance is measured in watts per square meter (W/m2). A pyranometer is designed to measure this irradiance from all directions.
