Impact of Surface Temperature of a Photovoltaic Solar Panel on Voltage Production
2022-06-03
Surface temperature of the photovoltaic solar panel plays a significant role during the electricity generation. Effect of surface temperature of a photovoltaic solar panel is experimentally investigated in this study. Water spray technique is applied to cool down the surface temperature of the photovoltaic solar panel. Maintain and keep low temperature of the photovoltaic solar panel during operation and exposure time to sun decreases the rate of cell degradation with time and to provide a solution for the overheating and dusty surface issues. The experiments include two Monocrystalline PV panels: one with a cooling system technique and the second without cooling system. Eight nozzles equipped in the cooling technique, distributed uniformly on the front side of the solar panel with an inlet water pressure of 2.5 bar. The performance of both panels was compared in terms of the volt production and the temperature of the panel. Both photovoltaic solar panels operated under the same conditions in the same place, and the slope was 21°based on the location of Buraimi city in Sultanate of Oman. The results showed that the cooling technique using 8 nozzles distributed uniformly working with an inlet water pressure 2.5 bar and remaining active for 15s and switched off for 180s can reduce the solar panel temperature and clean the surface of the solar panel. Maximum volt production was achieved by the photovoltaic panel with a cooling technique with a maximum uncertainty of ± 0.42. The cooling technique prevented overheating by keeping the panel clean and cool.
