Solar Tracker System using STM32407G-DISC-1 Board

Solar energy represents a significant renewable resource with the potential to substantially reduce carbon emissions and support sustainable development. However, the efficiency of solar panels is often limited by their fixed orientation, which restricts their exposure to sunlight as the sun traverses the sky. In response to this challenge, this study introduces a prototype solar tracker designed to optimize the performance of solar panels through dynamic adjustments. Featuring a dual-axis tracking system, the prototype continuously aligns the panels with the sun's position throughout the day, ensuring maximum light absorption. This dynamic approach leads to a marked improvement in energy collection compared to conventional static panels, which are only able to capture optimal sunlight during specific periods. The enhanced efficiency achieved through dynamic movement is crucial for bolstering the practicality and efficacy of solar power systems, promoting wider adoption of renewable energy technologies. By increasing energy capture, such systems contribute to a more sustainable energy grid and provide a cost-effective solution for both residential and commercial applications. The prototype's performance has been rigorously analysed based on real-time calculations of solar energy collection throughout the day, using the sun's positional axes as a reference. Results demonstrate that the dual-axis solar tracker achieves significantly higher energy output compared to static systems by optimizing panel alignment to maximize sunlight capture. These findings validate the effectiveness of the concept. Future efforts will focus on refining the tracker’s design, optimizing its algorithm for dynamic conditions, and further evaluating its performance under diverse environmental scenarios to enhance efficiency and reliability.
