| Sumario: | The growing integration of photovoltaic (PV) systems in modern energy infrastruc-tures calls for advanced and application-specific monitoring tools. This article intro-duces a comprehensive method for operational monitoring of PV installations using Supervisory Control and Data Acquisition (SCADA) systems. It presents both stand-ard and innovative performance indicators designed to improve energy management in self-consumption and grid-connected configurations. To address limitations in cur-rent standards such as IEC 61724-1, a new set of parameters is proposed. These include the self-consumption ratio (SCR), self-sufficiency ratio (SSR), and dedicated perfor-mance ratios for self-consumption (PR_SC) and grid export (PR_TG). Together, these metrics provide a clearer understanding of system efficiency and energy flow. The ar-ticle explores the use of WinCC Unified, a modern SCADA platform developed by Siemens, to implement these indicators. WinCC Unified offers advanced tools for re-al-time visualization, cloud and edge connectivity, historical data management, and user-friendly interface design. Its open architecture supports the integration of custom KPIs and analytics, enabling the creation of dynamic and informative dashboards. By leveraging digital tools like WinCC Unified, the proposed approach contributes to the development of intelligent, standardized monitoring solutions for PV systems, aligned with the evolving demands of smart grids and distributed generation. SCADA dash-board, designed in this work, offers more than just an attractive interface – it delivers real operational value. It brings together 21 key performance indicators along with the current date and time in a single, streamlined display, updated every 0.1 seconds for near-instant data visibility, which allows operators to instantly assess overall system health at a glance. This intuitive layout not only simplifies daily monitoring but also speeds up anomaly detection and response times, supporting quicker interventions and improving overall system reliability through complete real-time awareness. |
