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. Many instruments from several manufacturers exist to perform these tasks, such as a pyranometer and a pyrheliometer requiring a suite of at least these two expensive instruments and a solar tracker to perform the required measurements. Accordingly, the invention provides users with a single instrument with no moving external parts capable of measuring all three irradiance components, thereby simplifying the data acquisition and minimizing equipment cost whilst providing measurements with low uncertainty.
