Why is it necessary to do a good job in grounding the photovoltaic array?

If photovoltaic modules are installed on building rooftops or in the wilderness, they are more vulnerable to lightning strikes, which will not only damage the equipment of the photovoltaic power station but also cause hazards such as personal safety and fire accidents. Therefore, attention should be paid to the grounding and lightning protection issues of the photovoltaic system. Good lightning protection and safety grounding should be done for facilities such as brackets, combiner boxes, inverters, and transformers. The frames of the components and the brackets should be well connected, and the brackets can be equipotentially connected to the original grounding of the building.
