If you want to track the solar light in the vertical plane you need to build a separate sun tracker circuit.
Sun tracking solar panel circuit.
For solar panels control is best to use small motors with a suitable voltage and a maximum working current of 300 ma.
This solar tracker system is used for tracking the sun only in one plane the horizontal one.
The sun tracking solar panel consists of two ldrs solar panel and a servo motor and atmega328 micro controller.
Solar tracking system circuit fig.
Here is a simple low cost solar tracker circuit which automatically moves the solar panel in the direction of sun.
The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components.
Light dependent resistors produce low resistance when light falls on them.
Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position relative to the sun.
