Abstract

The increase of cell temperature with increased irradiance is probably the most
significant disadvantage of using Photovoltaic modules equipped with booster reflectors. The aim
of this study is to investigate the possibility of improving the performance of a photovoltaic water
pumping system by using a booster reflector and to keep the temperature of PV panels at a low
level by cooling PV panels with a film of water. The water required for covering the cells is fed by
the pump itself. By applying the modifications on the photovoltaic water pump system, significant
improvement in the output power from PV panels, and therefore in the pump flow rate, is
displayed in the experimental results.
