Cover Story: Digital Twin (DT) for photovoltaic (PV) systems emerges as the intersect of power system transformational approaches driven by digitalization, decarbonization, decentralization, and the massive adoption of cleaner energy sources. A DT enables real-time, bidirectional data exchange and control between physical assets and their digital replicas. Unlike digital models or shadows, DTs support automated monitoring, predictive maintenance, and AI-driven analytics. While there have been limited instances of PV-DTs for energy forecasting, fault detection, and maintenance optimization, their potential extends to enabling autonomous systems such as robots and wider energy network integration. This work explores DT frameworks, challenges, and robotics integration for enhanced management. View this paper
