In this method, cooling is done by conductive heat transfer on the backside of PV panels by using metal channels like Copper or Aluminum through a continuous water running jacket that can harness the heat and help heating the water for domestic use and also cool down the PV panels for better overall efficiency.
Liquid cooling of photovoltaic panels is a very efficient method and achieves satisfactory results. Regardless of the cooling system size or the water temperature, this method of cooling always improves the electrical efficiency of PV modules. The operating principle of this cooling type is based on water use.
1. It is possible to cool and clean the PV panels using the proposed cooling system in hot and dusty regions. 2. The cooling rate for the solar cells is 2 °C/min based on the concerned operating conditions, which means that the cooling system will be operated each time for 5 min, in order to decrease the module temperature by 10 °C.
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. The study was conducted under laboratory conditions. Water was sprayed on the front face of the panels. A water pump was responsible for spraying water in the cooling system.
Thus, the system developed in this work provides an attractive solution for solar farms to cool PV panels and simultaneously produces clean water that can be used for cleaning the dust from PV panels and/or for potable purposes. This work has successfully applied the atmospheric water sorption–desorption cycle to cooling a PV panel.
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.
