Elevated temperatures on the back surface of photovoltaic panels pose a challenge, potentially reducing electrical output and overall efficiency. To address this, a cooling system employing water spray and air was proposed and examined across three scenarios.
The cooling of PV panels by the techniques using water as cooling medium using power for water springs and pumps are categorized under active cooling of PVs by water. Such techniques are discussed as follows:
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.
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.
Electrospray cooling performance in PV panels was examined for different flow rates and irradiance values using water as the coolant fluid. As a result, it was determined that the optimum
Spray cooling is highly effective in arid areas, enhancing efficiency of PV panels. Photovoltaic panels suffer from significant efficiency losses at elevated temperatures, particularly in
They tested three cooling techniques acting on the PV panel back surface and verified that spray cooling is able to reduce the surface temperature up to 26.4 °C during sunny days as well as
