Photovoltaic module fault diagnosis and analysis method and system

The invention provides a photovoltaic module fault diagnosis analysis method and system, and relates to the technical field of power equipment operation and maintenance, and the method comprises the steps: obtaining fault archiving information, carrying out the photovoltaic power generation energy efficiency analysis, determining the fault influence degree, carrying out the target part division, obtaining a part affiliation result, constructing a monitoring queue list, and completing the monitoring deployment. And acquiring real-time monitoring data, transmitting the real-time monitoring data to the diagnosis and maintenance model, outputting an operation and maintenance compensation scheme, and performing operation and maintenance regulation and control on the photovoltaic module, thereby solving the problems that a fault diagnosis method of the photovoltaic module in the prior art is insufficient in intelligence, mainly depends on manpower or high-precision equipment inspection, is relatively high in mainte
