To achieve intelligent and refined operation and maintenance of photovoltaic power stations, a module-level monitoring scheme based on embedded edge computing and tiny machine learning(TinyML) was proposed. A three-layer architecture consisting of sensing nodes, edge gateways and cloud platforms was constructed. Embedded sensor nodes were deployed on the component side to collect current and voltage

curve characteristics in real time for accurate localization and classification of faults such as hot spots and aging. Finally, the diagnostic results were uploaded to the cloud. By sinking computing power to the network edge, this scheme effectively reduces the data communication load, achieves real-time detection and accurate localization of faults, and provides a novel design idea
for building an efficient and low-cost intelligent operation and maintenance system for photovoltaic power stations.
