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.
One of the effective methods of cooling is using water spray on photovoltaic panels. In this method, water is sprayed on the front or back of the panel surface, or both at the same time. Parameters such as water flow rate, number of nozzles, spraying height, and formation of water film are important.
Spraying water at a higher distance from the surface improves the electrical and thermal performance of the photovoltaic panel. The spray cooling process improves the thermal performance of the panel by convective heat exchange to the surface and also by cooling the peripheral air through evaporating and convective heat exchange.
In this method, water is sprayed on the front or back of the panel surface, or both at the same time. Parameters such as water flow rate, number of nozzles, spraying height, and formation of water film are important. By spraying the water onto a photovoltaic panel, the operating temperature can effectively regulate through cooling.
Cooling occurs when water is sprayed onto the surface of the photovoltaic panels, lowering the temperature of the panels. Moreover, water in contact with the boards specifically
