Sun Tracking Solar Panel Circuit

The movement of the sun is detected using two ldrs which are arranged on the solar panel in such a way that the intensity of light falling on it varies as the direction of sun changes.

Sun tracking solar panel circuit.

This solar tracker system is used for tracking the sun only in one plane the horizontal one. Circuit of solar tracking system. The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components. Two light dependent resistors are arranged on the edges of the solar panel.

For solar panels control is best to use small motors with a suitable voltage and a maximum working current of 300 ma. Solar tracking system circuit fig. The sun tracking solar panel consists of two ldrs solar panel and a servo motor and atmega328 micro controller. 1 shows the circuit of the solar tracking system.

Here is a simple low cost solar tracker circuit which automatically moves the solar panel in the direction of sun.
