How much water flows through a solar cooling system?The amount of water flowing through the cooling system depends on the intensity of solar radiation reaching the system. This radiation is also responsible for increasing the volume of gas in the expansion device. The proposed solution increased the electrical efficiency of the PV panels by 8.3%.
How does a solar PV system work?The recycled water is collected in a U-shaped borehole heat exchanger (UBHE), installed in an existing well to enhance the cooling capacity. The water exchanges heat with shallow-geothermal energy. Finally, the panel is again sprayed with water to cool it. The water in this cooling system first cooled the PV panel.
How does water cooling of PV panels work?Water cooling of PV panels is also studied by Irwan et al.where the performance of PV panels was compared with panels cooled by water flow on the front surface.
