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.
This research aims to find the power of three sizes solar panels for suitable of solar water pumps as 360 watts, 350 watts and 350 watts. From the results of comparing the power of the panel. Show that, the highest solar power is type three (350 watts, 2 solar panels) as 800 watts. Because the electric power depends on the receiving area and the light intensity …
