Key Technologies for O&M of Distributed Photovoltaic Systems

O&M management is critical to ensuring the long-term, stable operation of distributed PV systems. This article systematically outlines key technical aspects across three dimensions: fault diagnosis, performance optimization, and safety management. For fault diagnosis, we introduce intelligent diagnostic methods based on big data analytics. In performance optimization, we discuss practical techniques such as module cleaning and inverter efficiency improvements. Regarding safety management, we emphasize essential measures including electrical safety, fire prevention, and lightning protection.
