7. SOLAR IRRADIANCE
Solar Irradiance (or Solar radiation Energy Flow) through a horizontal surface with area of 1 m2, is measured in W/m2 [ or equivalently in (J/s) / m2 ], as it recorded in the visual to near-infrared bands. Under cloudy conditions, Solar Irradiance is reduced accordingly.
Solar irradiance values are supplied by the Kipp & Zonen CMP3 pyranometer[†].
