Description

technical field

[0001] The invention relates to the technical field of photovoltaic panel fault detection, in particular to a photovoltaic panel fault detection method, system, storage medium and electronic equipment based on a knowledge map. Background technique

[0002] Driven by the dual carbon goals, the photovoltaic industry has developed rapidly. As of September 2021, the installed capacity of solar power generation will be about 280 million kilowatts, a year-on-year increase of 24.6%. The photovoltaic panel is the core component of the photovoltaic power generation system, and the health status of the photovoltaic panel directly affects the stability of the output power of the photovoltaic power generation system. However, photovoltaic panels are directly exposed to the external environment, and their health status is affected by various factors such as temperature, light, wind and rain. Harsh environmental conditions can easily cause damage to photovoltaic panel batt...
