Sunalign Intelligent Solar Tracking System

Solar energy, being a renewable, clean, and abundant source of power, plays a critical role in the transition to sustainable energy systems. However, the efficiency of solar panels in harnessing this energy largely depends on their ability to continuously align with the sun’s position throughout the day. A fixed-position solar panel is suboptimal, as it only captures maximum energy when the sun is directly overhead. To address this limitation, the SunAlign project presents a dual-axis solar tracking system designed to maximize energy capture by continuously adjusting the solar panel’s orientation to face the sun. In addition to tracking sunlight, SunAlign integrates a temperature sensor to monitor the system’s thermal conditions. Overheating can reduce the efficiency of the solar panel and damage components, so the system is designed to send alerts if temperatures exceed safe operating levels. The temperature data, along with other system performance metrics, is transmitted in real-time to a custom-built web application using the ESP32’s built-in Wi-Fi module. The web application provides users with a user-friendly interface to monitor various parameters, including panel position, temperature readings, and weather conditions. It also generates maintenance alerts when service is required, ensuring long-term reliability and performance of the solar tracking system. To enhance the system’s robustness, the SunAlign project is designed with an automatic override in cases of inclement weather, such as storms or heavy rain. For instance, if bad weather is detected (via external weather data or additional sensors), the system automatically positions the solar panel in a safe, horizontal configuration to minimize damage from wind or rain. The web application also allows users to manually control the panel position and adjust settings remotely from any location.
