Design and Implementation of a Dual-Axis Solar Tracking System STS

Abstract

Solar energy is converted into electrical energy using photovoltaic panels. The production of electricity from the solar panel is increased by the increase in the collection of solar radiation by the solar panel. To track the sun in vertical and horizontal directions, a dual-axis tracking prototype has been developed to capture the maximum sun rays by tracking the movement of the sun in four different directions. One axis is horizontal, which allows the solar panel to move left and right. The other axis is vertical and allows the panel to turn up and down. The result of this new development provides the solar panels with extensive freedom of movement. This process makes use of the Light Depending Resistor (LDR), which is important for detecting the sun's light by following the source of the light location. Proteus software is being used to design the circuit for the Arduino mega microcontrollers and H-Bridge IC chip. This implemented system can save more energy and probably offer a greater reduction in cost. The project discusses the process of hardware development and the control process of tracking the sun, as well as the circuit design.
