This paper investigates an alternative cooling method for photovoltaic (PV) solar panels by using water spray. For the assessment of the cooling process, the experimental setup of water spray cooling of the PV panel was established at Sultanpur (India). This setup was tested in a geographical location with different climate conditions. It was found that the temperature of the panel decreased from 53 to 23 °C and the total power was increased by 15.3% by the water spray cooling. The effectiveness of the system is also increased by its cleaning effects. The efficiency of this solar PV is reduced with the increase of panel temperature. The experiments showed that the PV cell efficiency was dropped by 0.5% with an increase of 1 °C in panel temperature. However, the electrical efficiency of the panel was increased by 0.28%/0.2 °C of temperature drop by the single nozzle spray cooling.
