Pyranometer Basics

The Solar Radiation Sensor, or solar pyranometer, measures global irradiance, the amount of solar energy per unit area per unit time incident on a surface of specific orientation. The global irradiance includes direct sunlight and diffuse sunlight. Pyranometer is to be located far from any kind of obstruction, which might reflect sunlight (or sun shadow) onto the pyranometer itself. The sunlight sensor must be installed at the same azimuth and tilt angle than the PV array.
