Margaret R E, Sunitha P, C. S Suresh Babu, Ragib R Sharief and Syed Ahmed Osama 06 02 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 solarradiation 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 sunbeamswhich maximises the exposure of solar panel to the Suns 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 themicrocontroller 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 Copyright (c) World Journal of Pharmaceutical Seiences.
