Direct irradiance
WebThe outcome of the procedure is direct normal and global horizontal irradiance. Third, direct normal and global horizontal irradiance are used for computing diffuse and global tilted irradiance (irradiance in plane of array, on tilted or tracking surfaces) and/or irradiance corrected for shading effects from surrounding terrain or objects. WebMar 1, 2015 · This estimation involves two steps: 1) decomposition of GHI into direct and diffuse horizontal components and 2) transposition of direct and diffuse horizontal irradiance (DHI) to POA irradiance.
