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.
The results found that, as the cooling water flow rate between 25 and 250 LPH, the solar cell efficiency tends to increase as the flow rate increases. The solar panel has a maximum …
