The study includes the design and implementation of a single-axis sun-tracking system for PV panels, while evaluating it with other methods. The control system utilises an optical tracking technique based on the geographical location of PV Panels with respect to the Sun. The methodology used in this work is a single-axis sun-tracking system that utilises two LDRs (Light-Detecting Resistors). The evaluation of maximum irradiance efficiency is performed with respect to a fixed system and with other solar tracking systems for optimisation. The proposed sun-tracking system uses an advanced controller and an H-Bridge, which utilises MOSFET transistors. The tracker mount controls the panel to align it at the correct angle, for exploiting the maximum irradiance to boost the efficiency of the panel. The controller assesses the angle required to align the PV panel, and the driver rotates the motor shaft. The motor controls the tracker’s movement. The algorithm calculates the exact sun’s position using time with respect to the geographical location. The paper also discusses other methods of sun-tracking systems to integrate with different combinations of STS and control mechanisms for optimisation, as future work.
