Sun Tracking Solar Panel Circuit

Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position relative to the sun.

Sun tracking solar panel circuit.

The sun tracking solar panel consists of two ldrs solar panel and a servo motor and atmega328 micro controller. For solar panels control is best to use small motors with a suitable voltage and a maximum working current of 300 ma. Here is a simple low cost solar tracker circuit which automatically moves the solar panel in the direction of sun. Light dependent resistors produce low resistance when light falls on them.

1 shows the circuit of the solar tracking system. If you want to track the solar light in the vertical plane you need to build a separate sun tracker circuit. The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components. Circuit of solar tracking system.

This solar tracker system is used for tracking the sun only in one plane the horizontal one.
