How To Make Solar Tracker System Using Arduino And LDR Presentation

Introduction to Solar Tracker System
A solar tracker system is designed to maximize the efficiency of solar panels by orienting them towards the sun. Arduino, a popular microcontroller platform, can be used to control the movement of solar panels. Light Dependent Resistors (LDRs) are sensors used to detect sunlight intensity and guide the solar panels' movement.	Image Source

Basic Operation
LDRs sense sunlight intensity and provide analog readings to Arduino. Arduino compares the readings from both LDRs to determine the direction of maximum sunlight. Based on the readings, Arduino sends signals to the servo motors to adjust the position of the solar panels.	Image Source

Calibrating LDRs
Place the solar tracker system in an open area with ample sunlight. Adjust the position of the solar panels manually to face the sun. Monitor the analog readings from both LDRs using Arduino's serial monitor.	Image Source

Benefits of Solar Tracker Systems
Increased energy generation: Solar panels facing the sun directly capture more sunlight, leading to higher energy production. Improved efficiency: Solar tracker systems can increase the efficiency of solar panels by up to 30% compared to fixed installations. Optimal power output: Continuous tracking ensures the solar panels operate at their maximum power point, maximizing energy yield.	Image Source
