Solar Tracker Circuit Diagram. The previously discussed solar tracker post included some sensors in the form of ldrs for monitoring the sun s position in the sky and accordingly providing the commands to the control circuit and the motor so that necessary adjustments are quickly made to the panel for maintaining the required accuracy of the panel with the sun rays. We all know that when the intensity of light falling on a ldr increases its resistance decreases.
The pwm inputs of two servos are given from digital pins 9 and 10 of arduino. The previously discussed solar tracker post included some sensors in the form of ldrs for monitoring the sun s position in the sky and accordingly providing the commands to the control circuit and the motor so that necessary adjustments are quickly made to the panel for maintaining the required accuracy of the panel with the sun rays. Here ldr is connected with a series resistor r3 r4 hence when the intensity of light falling.
Circuit implementation of dual axis solar tracker system.
Here ldr is connected with a series resistor r3 r4 hence when the intensity of light falling. Four ldrs and four 100kω resistors are connected in a voltage divider fashion and the output is given to 4 analog input pins of arduino. This solar tracker control system is designed to take light measurements from the east and west left and right side of the solar panel and determine which way to move the panel to point it directly at.
