Arduino based Solar Tracker in Dual Axis
A solar tracker system positions the object at an angle relative to the Sun. The system maximizes the electricity production by moving solar panels to follow the sun throughout the day, optimizing the angle at which the panels receive solar radiation. The goal of the project is to develop a laboratory prototype of a solar tracking system, which is able to enhance the performance of the photovoltaic modules in a solar energy system. The operating principle of the device is to keep the photovoltaic modules constantly aligned with the sunbeams, which maximises the exposure of solar panel to the Sun’s radiation. As a result, more output power can be produced by the solar panel. The system utilises an ATmega328P microcontroller to control the motion of two servo motors, which rotate the solar panel in two axes. The amount of rotation is determined by the microcontroller, based on inputs retrieved from the four photo sensors located next to solar panel. The objective of the project is to design and implement a functional solar tracking system which is able to keep the solar panel aligned with the sun, or any light source repetitively
