Real-Time Clock (RTC)-Based Sensorless Solar Tracking System

The Real-Time Clock (RTC)-Based Sensorless Solar Tracking System is designed to automatically adjust the position of a solar panel according to the calculated position of the sun throughout the day without using light sensors such as LDRs.

The RTC provides accurate time information to the controller. Based on the programmed solar-position schedule, the system calculates the required panel position and operates the motor to move the solar panel from east to west during the daytime. At the end of the day, the panel automatically returns to its starting position for the next day's operation.

Working Process

RTC Provides Time → Controller Determines Solar Position → Required Panel Angle Calculated → Motor Activated → Solar Panel Position Adjusted → Limit Position Checked → Solar Power Generated → Evening Return-to-Start Position

Tracking Process

🌅 Morning: Panel positioned toward the East
☀️ Daytime: Panel gradually follows the calculated solar position
🌇 Evening: Panel moves toward the West
🌙 Night: Panel returns to the predefined East/start position
