📘 Introduction

As the demand for renewable energy is increasing, solar panels have become one of the most widely used technologies in sustainable power generation. However, fixed solar panels fail to utilise maximum sunlight throughout the day due to continuous changes in the sun’s position. This results in reduced efficiency and lower power output. To overcome this limitation, solar tracking systems are employed, which automatically adjust the panel orientation to face the sun.

This project demonstrates an IoT-Based Dual Axis Solar Panel Monitoring and Tracking System using Arduino UNO. Unlike single-axis trackers, the dual-axis system tracks the sun’s movement in both horizontal (azimuth) and vertical (elevation) directions, ensuring maximum solar exposure throughout the day. The system uses four LDR sensors arranged in pairs to detect sunlight intensity in both axes. Based on these readings, two DC motors controlled via L293D motor drivers rotate the solar panel for precise alignment.

In addition to tracking, the project integrates a DHT11 temperature and humidity sensor, solar voltage measurement using a voltage divider circuit, and a current sensor for real-time power monitoring. All sensor values are displayed locally on a 16×2 LCD display.

For IoT functionality, an ESP8266 Wi-Fi module uploads temperature, humidity, voltage, and current data to the ThingSpeak cloud platform, enabling remote monitoring and graphical analysis. The system operates on a 12V rechargeable battery, making it portable, efficient, and suitable for real-world renewable energy applications. The dual-axis tracking mechanism significantly improves energy generation and overall system efficiency.

⚙️ Methodology

The system functions by constantly checking the intensity of sunlight through two LDR sensors located on opposite sides of the solar panel. Arduino UNO takes readings and compares them. When one LDR gets more sunlight than the other, Arduino triggers a signal to the L293D motor driver, which turns the DC motor until the solar panel receives maximum sunlight. This maximizes orientation throughout the day.In addition to tracking, the system also keeps an eye on temperature and humidity using the DHT11 sensor, and voltage and current provided by the solar panel using a voltage divider circuit and current sensor. These values are shown on the 16×2 LCD display for real-time monitoring.For remote monitoring, the Arduino interacts with the ESP8266 Wi-Fi module, which sends all the sensor readings to the ThingSpeak IoT cloud. The users can view live graphical trends of voltage, current, and environmental parameters remotely. The entire system is powered by a 12V rechargeable battery, thus being self-sustainable and IoT-compatible.
