Automatic Solar Tracking System Circuit Diagram. The heart of the above circuit is two voltage comparators made using lm358 dual op amp. 103 33 263 senior lecturer 2 anik sarker department of eee id.
A microcontroller based design methodology of an automatic solar tracker. Solar tracking system is the most appropriate technology to enhance the efficiency of the solar cells by tracking the sun. Above can be solved by our system by automatic tracking the solar energy.
The block diagram below shows system architecture it consist of a ldr sensor senses max solar power which is being given to the microcontroller through the adc which digitizes the ldr output.
The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components. How the dual axis solar tracker concept works the device is able to track the daytime motion of the sun precisely and shift in the vertical axis accordingly. So solar panel should continuously rotate in the direction of sun. As you can see the circuit is very simple and can easily be built with help of a small breadboard.
