Solar Tracking System Using Motor
Aim:-
Solar tracking enables more energy to be generated because the solar panel is always able
to maintain a perpendicular profile to the sun’s rays.
Abstract:-
Solar energy is rapidly advancing as an important means of renewable energy resource.
Solar tracking enables more solar energy to be generated because the solar panel is able to
maintain a perpendicular profile to the sun’s rays. Though initial cost of setting up a solar
tracking system is high, this paper proposes a cheaper solution. Design and construction of a
prototype for solar tracking system with single degree of freedom, which detects the sunlight
using Light Dependent Resistors (LDR), is discussed in this paper. The control circuit for the
solar tracker is based on an ATMega8 microcontroller. This is programmed to detect the sunlight
through the LDRs and then actuate the motor to position the solar panel where it can receive
maximum sunlight.. Theoretical analysis and research results have been shown in this project to
advocate that the designed system realized precise automatic tracking of the sun and can greatly
improve the utilization of solar energy.

1. What microcontroller using? And why?
Ans: We are using AURDINO, (ATMEGAfamily,AVR)
 Because “Arduino is an open-source
 Electronics prototyping platform based on flexible, easy-to-use hardware and software.
 It’s intended for artists, designers, hobbyists, and anyone interested in creating
interactive objects or environments.
 “Arduino can sense the environment by receiving input from a variety of sensors and can
affect its surroundings by controlling lights, motors, and other actuators.
