Problems solved by technology

The failure of the lightning protection device will cause the photovoltaic cell to lose its lightning protection. At the same time, the failed lightning protection device may also spontaneously ignite and cause further losses. Therefore, it is necessary to replace the failed lightning protection device in time, and the damaged photovoltaic cell must also be replaced in time. , otherwise the conversion efficiency will be greatly reduced

Existing lightning protection devices or other photovoltaic equipment cannot reflect the working status and location information of photovoltaic cells and lightning protection modules, resulting in a heavy workload for operation, maintenance and maintenance of photovoltaic power stations, unsafe staff, and untimely discovery of damaged parts
