Dual Axis Solar Tracker System Using Arduino and LDR Full Working Project

Dual Axis Solar Tracker In this post we are going to discuss how to make a Solar tracker project and for making it we are using an Arduino board. We need to make this project because generally, the solar panels that are widely used to generate electricity are not much efficient. As the position of the solar panels are fixed towards one direction only but the sun changes its position, and this affects the electricity generation.

How does it work?

We fixed four LDR on the sides of the solar plate so it starts calculating and comparing that from which direction the maximum intensity sunlight is coming. After comparing the servo motors start moving and turn the face of the solar plate towards that direction. By doing this practice we can generate maximum electricity than other solar panels. For moving the solar plate we are using two servo motors. Arduino microcontroller helps to make all processing and calculation.

Components Required to make dual axis Solar tracker:-

• Arduino Uno
• 4 LDR
• 4- 10K Ohm Resistor
• 2- Servo Motor
• Solar Panel
• Jumper wire
• Breadboard
