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 presents the study and construction of solar aerators that can control motor speed by a wireless signal. The proposed machine used solar panels with 570 watts to generate electricity and collected electric energy with 130 AH battery capacity. The 250 watts DC motor was used to rotate the turbine which could be used with 6 or 8 propeller turbines.
