The electrical performance and reliability of Solar PV Power Generation System (SPVPGS) is strictly influenced by irradiance, elevated solar PV cell operating temperature, dust and wind. In order to utilize solar PV power and increase SPVPGS efficiency, it is necessary to keep both the solar PV cell temperature and reflection as low as possible. This article presents a new technique to improve solar photovoltaic (PV) panel efficiency. In this work, the efficiency of SPVPGS is enhanced by maintaining solar PV panel temperature as minimum using sprayer arrangement. Water-cooling system is implemented using a chilled water source and a perforated tube which is fitted on the top of the solar PV panel. The cooling water directly wets the solar PV panel active surface, thereby decreasing the temperature of the panel at the same time which decreasing the light reflection loss and cleaning the solar PV panel surface. Experimental results show that the efficiency of solar PV panel is increased 2–4% more than traditional stand alone SPVPGS by reducing thermal loss, dust effect and reflection loss.
