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.
Pulsating spray cooling system for PV modules
Iranian scientists have assessed a new active approach for solar module cooling based on water spraying. Water sprayed from different angles can reduce the operating temperature of PV modules, with limited water consumption. However, the team noted that they have yet to assess the economic viability of the system.
