Background Under the trend of the global energy structure toward clean and sustainable transformation, the solar photovoltaic power generation technology has become a key support in the new energy field by the core advantages of environmental protection and reproducibility. The photovoltaic panel is used as a core energy conversion component of the photovoltaic power generation system, and the running state of the photovoltaic panel directly determines the power generation efficiency, the stability and the service life of the whole system. Therefore, various faults in the operation process of the photovoltaic panel are accurately and real-timely monitored, and an alarm is timely triggered, so that the intelligent photovoltaic panel is a core requirement for guaranteeing efficient operation and maintenance of photovoltaic projects and reducing safety risks. Through searching, the patent document with publication number CN120433719A discloses an automatic warning device and method for the faults of a solar photovoltaic panel, the device is characterized in that a tooth groove plate, a tooth column and a fault scanning component are arranged at the top end of a bracket, the sleeve block at the bottom of the upright post is matched with the telescopic temperature measuring assembly, so that the monitoring of hot spots, hidden cracks and abnormal temperature rise of the photovoltaic panel is realized. The intelligent temperature measuring device comprises a fault scanning assembly driven by a bidirectional motor, a telescopic temperature measuring assembly, a temperature sensor and an alarm, wherein the fault scanning assembly can drive a thermal imager to reciprocate above a photovoltaic panel and rotate for patrol, and the telescopic temperature measuring assembly drives a plurality of temperature sensors to be attached to the bottom of the photovoltaic panel for measuring temperature through an electric push rod, a gear rack transmission and a movable plate of a V-shaped structure, so that fault early warning is finally realized through the alarm.
