Web Server Based Data Monitoring System of PV Panels Using S7-1200 PLC

Abstract

This This paper presents the design and implementation of a solar panel data monitoring system using a Web Server as a real-time operating system. The system is built via the Siemens S7-1200 Programmable Logic Controller (PLC) and programmed using TIA (Totally Integrated Automation) Portal V17 software. This approach enables real-time data collection and visualization of essential parameters such as voltage, current, power output, temperature, irradiance, and environmental conditions. The S7-1200 PLC serves as the central control unit, interfacing with the PV panels and gathering data. The acquired data is then transmitted to a web server, which hosts a user-friendly interface accessible through web browsers. Users can remotely monitor the performance of PV panels, track historical data trends, and receive alerts in case of anomalies. This web server-based system offers a convenient and efficient solution for effective PV panel management, enabling users to optimize energy production, detect issues promptly, and make informed decisions for maintenance and operational improvements.
