1. How long is the service life of distributed photovoltaic power generation system?

At present, the service life of distributed photovoltaic power generation is 20-25 years.

2 is photovoltaic power generation system harmful to users?

Photovoltaic power generation system is based on the principle of photovoltaic effect to convert solar energy into electric energy, no pollution, no radiation, inverter, distribution cabinet and other electronic devices have passed the EMC (electromagnetic compatibility) test, so there is no harm to human body.

3. Is it necessary to disconnect photovoltaic power generation system in thunderstorm weather?

Distributed photovoltaic power generation systems are equipped with lightning protection devices, so there is no need to disconnect. In order to ensure safety, it is suggested to disconnect the circuit breaker switch of the combiner box and cut off the circuit connection with the photovoltaic module, to avoid the harm of direct lightning that cannot be removed from the lightning protection module. The operation and maintenance personnel should timely detect the performance of the lightning protection module, to avoid the harm caused by the failure of the lightning protection module.

4. Do PV modules need maintenance after 4 days of snow?

If there is heavy snow on the components after snow, it needs to be cleaned. You can use soft objects to push the snow down, and pay attention not to scratch the glass. The components have a certain load-bearing, but you can't step on the components to clean, which will cause hidden damage to the components and affect the service life of the components. It is generally recommended not to wait for the snow to be too thick to clean, to avoid excessive freezing of the components.

5. How often is it suitable for the later operation and maintenance?

The later operation and maintenance are mainly to wipe the components, and the operation and maintenance times are different in different regions. Generally, in the place where there is more rain, there is no need to wipe manually. The place with less rain and the area with more dust can increase the frequency of cleaning.
