"sprayed around 15.6 liters/day of water over the modules at temperatures beyond 45 degrees Celsius, which in turn raised the water temperature to an average of 30 degrees Celsius... temperature sensor fixed on the back of the solar module that is connected to a microcontroller producing a pulse width modulation (PWM) signal... triggers a Mosfet acting as a switch between the system's solenoid valve, which is placed between the water tank and the spraying unit, and the power supply"
