Influence of Clouds and Aerosols to the Haze of the Sunshape
Abstract
The CSR is the thin aureole around the sunshape and results from the forward scattering of direct sunlight by atmospheric aerosols, such as dust, water droplets or ice crystals present e.g. in slight clouds. Solar energy concentrating systems typically collect the direct solar radiation originating from the disk of the sun and a fraction of the CSR. With increasing scattering influence the maximum possible concentration is reduced. This depends on several factors, but knowledge of the CSR can help in predicting or evaluating the efficiency and overall performance of solar concentrating systems.
