Abstract:
The relentless pursuit of sustainable energy solutions has positioned solar power as a cornerstone in the global transition away from fossil fuels. However, the inherent efficiency of photovoltaic (PV) systems remains critically dependent on the consistent and optimal capture of solar irradiance. A pivotal factor influencing this capture is the angle of sunlight incidence upon the solar panels. Static solar panel installations, while convenient, suffer from suboptimal performance due to the sun’s diurnal and seasonal movements, leading to significant energy losses. To counteract this limitation, a solar tracking system emerges as a dynamic solution, capable of maximizing power output by continuously reorienting the panel to maintain perpendicular with the sun's rays throughout the day. This paper delves into the design, implementation, and evaluation of a sophisticated dual-axis solar tracking system, augmented with an integrated LCD display for real-time monitoring of crucial performance metrics such as power output and ambient light intensity. At the heart of this system lies an Arduino Uno R3 microcontroller, selected for its robustness, ease of programming, and extensive community support. This microcontroller orchestrates the precise movements of servo motors, which are tasked with adjusting the panel's azimuth and altitude. Crucially, the system employs light-dependent resistors (LDRs) as its primary sensory input, enabling real-time sunlight detection and tracking. The LDRs, strategically positioned around the solar panel, provide differential light intensity readings, allowing the Arduino to accurately determine the sun's position and command the servo motors to achieve optimal panel alignment. To rigorously assess the efficacy of the proposed tracking system, a comprehensive experimental analysis was conducted. This involved a direct comparison between a static solar panel setup and the newly developed dual-axis tracking system. The results of this comparative study revealed a substantial and quantifiable increase in power generation achieved by the tracking system, underscoring its practical value in enhancing energy harvesting. The experimental findings presented in this paper serve to validate the effectiveness of the proposed system as a viable strategy for significantly boosting energy efficiency in solar power generation. Looking beyond the immediate benefits, the study also proactively explores avenues for future system enhancements. These include the seamless integration of Internet of Things (IoT) technologies for remote monitoring and control, the incorporation of artificial intelligence (AI) algorithms for predictive tracking and adaptive optimization, and the potential application of machine learning (ML) techniques to further refine system performance based on historical data and environmental patterns. This forward-looking perspective aims to position the proposed system as a platform for continuous improvement and adaptation within the rapidly evolving landscape of renewable energy technologies.
