Results showed that front cooling system and back cooling system could reduce the working temperature of solar panels by 42% and26% in average when comparing to the control system. The decrease of working temperature of solar panel affected the increase of its electrical power production performance of the tested panel with front cooling system ...
ABSTRACTThe research was aimed to improve Photovoltaic (PV) efficiency by using water as a coolant in the cooling system in order to reduce working temperature of PV. There were 2 experiments; spraying water on the front PV surface and dropping water on the front PV surface. 40 watts mono-crystalline silicon PV type was used in the experiment.
