Abstract
The major problem associated with the solar panel is its efficiency. Most of solar panels are less efficient because it is not able to convert the maximum of the sun’s energy. The issue is there with the non-movement of solar panel with the sun’s direction. This can be achieved by a solar tracking device that moves the panel with the direction of the sun. The tracker consists of the physical components such as Servo motor and frame. Second is the Control panel that consists of Light Dependent Resistor (LDR), a comparator and an Arduino UNO. This paper presents the design and Fabrication of the automatic solar tracking device. The model is based on the principle that when sunlight falls on LDR installed on the panel, the input is given to the Aurdino and then it gives a command to the servomotor to align its position where the intensity is maximum so that maximum efficiency is achieved.
