Air-assisted water spray for PV module cooling

Turkish researchers have developed a cooling technique in which water is sprayed via an air-assisted external mixing flat fan nozzle. The system can produce smaller droplet sizes to ensure the even distribution of water on panels.Researchers at Ataturk University in Turkey have evaluated the impact of water spray cooling on solar panel performance. They have proposed a number of technical improvements to optimize and scale up this active cooling technology. The scientists said in "Optimization of operational parameters for a photovoltaic panel cooled by spray cooling" - recently published in Engineering ...
