Correction of Shading Effects on Different Components of Solar Radiation

There have been many published articles describingshading effect algorithms for solar irradiation mapping indifferent components, that enabling scientists to gain experiencewith new techniques at low cost. The maps for diffuse, direct and global Solar irradiation havebeen calculated in combination satellite image data (Input data insystem) for a shorter period of one day. structured together usingthe “Inverse distance to a power” interpolation method.The Global and Diffuse irradiation maps were calculated with analgorithm based for correcting shading effects related to theorography estimated in Horizontal Plane and evaluate it on anyinclined plane using the sky brightness and clearness index andthe relative optical attenuation factor of the atmosphericthickness. The Direct irradiation is mapped as the combinationbetween global and diffuse irradiation. The tests of this methodwere carried out on several large sites, and showed good results.Keyword: Direct and global irradiation, Diffuse circumsolar andisotropic, index of shading effect
