How to Choose the Right Sun Tracker?

A complete measurement of solar irradiance includes global (GHI), direct (DNI), and diffuse (DHI or DIF) radiation. To accomplish this, a high-quality solar monitoring station typically comprises an automatic sun tracker fitted with instruments to measure these components individually. Depending on the application, long-wave radiation and reflected short-wave radiation may be added to provide the total radiation balance. This is especially relevant for meteorological and climatological observations. Furthermore, ultraviolet radiation and other measurements may also be taken.
