improving the effectiveness of a photovoltaic water pumping system by using booster reflector and cooling array surface by a film of water

the increase of cell temperature with increased irradiance is probably the mostsignificant disadvantage of using photovoltaic modules equipped with booster reflectors. the aimof this study is to investigate the possibility of improving the performance of a photovoltaic waterpumping system by using a booster reflector and to keep the temperature of pv panels at a lowlevel by cooling pv panels with a film of water. the water required for covering the cells is fed bythe pump itself. by applying the modifications on the photovoltaic water pump system, significantimprovement in the output power from pv panels, and therefore in the pump flow rate, isdisplayed in the experimental results.
