Abstract:
Due to the rotation of the earth in an orbit, direction of the Sun changes relatively. This research represents a setup, which is fabricated to minimize the angle of incidence between incoming light from Sun and a flat photovoltaic (PV) panel to increase the intensity of the light received. It increases the power generated by an installed power generating unit.
The setup consists of a mechanical mechanism to tilt the flat PV panel towards the Sun. This mechanism is derived by DC motors having a high reduction ratio. Voltage supplies to these motors are controlled by the Light Dependent Resistor (LDR) sensors by the means of electronic circuits.
This research aims to analysis and apply a dual axis sun tracker to generate maximum electrical power. The magnitude of energy intensification produced by the SPV panel using a tracker is evaluated by comparing it to the one without a tracker. Efficiency of the PV facility can be improved by 60.22% with a the dual-axis tracking system.
