Abstract:
In this study, a Raspberry Pi 4 Model B is used to create and install a complete monitoring system for a photovoltaic (PV) panel. Intending to optimize the PV panel's energy harvesting process, the system guarantees effective power management and real-time data monitoring. A Maximum Power Point Tracker (MPPT), which is essential to the setup and improves the PV panel's energy extraction efficiency, is the key to optimizing the system's performance in a range of environmental circumstances. The central processing unit of the monitoring system is a Raspberry Pi 4 Model B, which communicates with the MPPT, the PV panel, and the lead acid battery. To ensure self-sufficiency, the Raspberry Pi not only controls the data gathering and processing tasks but also gets its operating power from the PV panel via the MPPT. The Raspberry Pi's dual function demonstrates the effectiveness and usefulness of the device in renewable energy applications. Real-time monitoring of several key metrics, including voltage, current, temperature, and PV panel power output, is one of the system's key characteristics. These indicators are essential for evaluating the PV system's health and performance. The gathered data is processed and displayed on a simple platform that can be accessed from a distance, making it easier to monitor and analyze the data continuously. The importance of the MPPT is highlighted in terms of maintaining ideal power delivery to the Raspberry Pi and the lead acid battery, assuring reliable and effective energy storage and utilization. This project demonstrates how reliable and effective renewable energy systems can be made by integrating affordable, easily accessible technology, such as the Raspberry Pi, with modern power management technologies. The results show notable gains in energy efficiency and offer insightful information about the functioning of solar systems, which advances the field of sustainable energy solutions.
