Learn MoreLiquid 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.
This is the simplest way of cooling PV modules, so it is very popular. This method increases the energy efficiency and cost-effectiveness of the system with a limited investment. Passive cooling with air is the cheapest and simplest method of removing excess heat from PV panels. In such a solution, the PV modules are cooled by natural airflow.
A hybrid Photovoltaic/Thermal (PV/T) system, as seen in the figure below, consists of PV modules and a cooling system. The cooling agent, i.e. water, is sprayed on the surface area of the PV panel by using a fan . When spraying water on the surface of the PV module, the temperature decreases and the electrical efficiency increases (Fig. 3).
Proper cooling can improve the electrical efficiency, and decrease the rate of cell degradation with time, resulting in maximisation of the life span of photovoltaic modules. The excessive heat removed by the cooling system can be used in domestic, commercial or industrial applications.
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.
Future research must be focused on harvesting heat from the surface of a PV module effectively and cooling thereof in a more controlled and stable manner. As learned from the reviewed studies, the following cooling technologies are found to be promising based on materials used, capital cost and performance:
