Importance cleaning of PV modules for grid-connected PV systems in a desert environment

摘要: There is a great potential for solar power utilization in the desert region south of Algeria by employing photovoltaic (PV) modules. The accumulation dust on surface cause significant degradation conversion efficiency PV This work tries to estimate day loss generated energy caused deposition modules based an experimental setup grid-connected plant. measurements are carried out under outdoor condition Adrar, Algeria. study reveals that leaving array without cleaning it not recommended Saharan environmental conditions which significantly reduce output.
