Description

technical field [0001] The present invention relates to the technical field of new energy exploration, in particular to the exploration technology of large-scale solar power generation, and specifically to a system for measuring the generating power of photovoltaic modules. Background technique [0002] Photovoltaic modules are the core of solar power generation systems, and the working status of each module is different in actual operation. However, the monitoring system in the prior art does not analyze the working status of the components. At the same time, due to the wide distribution and remote location of the photovoltaic power generation system, it brings great challenges to the management and communication of the components, and the management personnel cannot timely understand the working status of the components. state, failure to understand the fault in time, not only reduces the power generation, but also has potential safety hazards. [0003] The working status...
