Solar irradiance incident on the surface of the earth is typically classified into three components: global horizontal irradiance (GHI), diffuse horizontal irradiance (DHI) and direct normal irradiance (DNI). Accurate measurements of these irradiance components are vital for many applications but for an ever-increasing number of PV sites, in addition to measuring the GHI, the measurement of DHI is mandated or required.
