he innovative cooling system for solar cells uses earthenware devices (made of clay) mounted on the rear side of photovoltaic (PV) panels. These devices, filled with water, absorb heat from the panel’s rear surface. As the water evaporates, it creates a cooling effect, reducing the temperature of the solar cells by up to 20°C. This method is particularly effective in hot, dry climates, where it can improve solar power generation by preventing heat buildup.
