RENEWABLE ENERGY TRAFFIC LIGHTTHROUGH SOLAR TRACKING SYSTEM
Introduction
Renewable energy house is operated under solar power with solar tracking system
to achieved 99% solar efficiency in domestic home
Scope objective
The major purpose of solar tracking system is to gather maximum amount of
power supply by means of tracking the solar panel. As soon as the system is
switched on, the solar panel comes to the initial position, i.e. towards east.
Working principle
There are four LDR which is set each in 45o to keep tracking of the sun from sun
rise to sun fall. As soon as the light falls on the first LDR, the signal will be sent to
IC 89C51 microcontroller. This in turn controls the stepper motor position i.e. first
quarter 0-45o.
As the sun rises when the sun light fall on the second LDR i.e. second
quarter 45-90o, automatically first LDR is put off and the second one gets on. The
signal from the second LDR goes to the IC and in turn goes to the stepper motor to
change its position, i.e. 45-90o. The same process goes on till the sun falls down. So
we are able to track the sun continuously. The electric energy thus obtained from

the solar cell goes to a storage cell / battery and it is stored. When this energy is
needed it is obtained by using an inverter. It is also programmed, regarding the
time of load on and load off. here load is traffic light with timer control unit
