Guangxi photovoltaic power generation editor to share some common questions and answers about the installation and maintenance of solar photovoltaic system:
Is it necessary to disconnect photovoltaic power generation system in thunderstorm weather?
A: distributed photovoltaic power generation systems are equipped with lightning protection devices, so it is not necessary to disconnect them. In order to ensure the safety, it is suggested to disconnect the circuit breaker switch of the combiner box and cut off the circuit connection with the photovoltaic module, so as to avoid the damage caused by direct lightning stroke that cannot be removed by lightning protection module. Operation and maintenance personnel should timely detect the performance of lightning protection module to avoid the harm caused by failure of lightning protection module.
How to clean PV modules?
A: rain water can be clean, and no special maintenance is required. If you encounter adhesion dirt, you can simply wipe it with soft cloth and water. It is recommended to use soft brush and clean and mild water to clean the glass surface of photovoltaic module, and the cleaning force should be small to avoid damaging the glass surface. The module with coated glass should pay attention to avoid damaging the coating layer.
Is there a risk of electric shock when wiping with water?
A: there is no danger to wipe with water. The photovoltaic power generation system and modules are insulated and grounded. However, in order to avoid electric shock injury and possible damage to components caused by wiping components under high temperature and strong light, it is recommended to clean the components in the morning or late afternoon.
