About the solar panels FAQs

- Jan 15, 2019-

General questions about the solar panels that everyone cares about:


1. Will it be an electric shock when you touch a solar panel?


 Generally, solar panel photovoltaic systems have lightning protection measures. However, when thundering and raining, do not touch bare metal parts such as solar panels and photovoltaic supports to avoid accidents.


2. If the grid is powered off, can PV still be used?


A solar panel photovoltaic system can generate electricity. The grid-connected inverter has island protection, the grid is powered off, and the solar panel photovoltaic system automatically stops running, which can prevent the system island from running, so as to avoid accidents.


3. Will solar panels be insufficient when winter is cold?


The factors directly affecting the solar panel's power generation are the irradiation intensity, the duration of sunshine, and the operating temperature of the solar panel assembly. The winter irradiation intensity will be weakened, the sunshine duration will be shorter, and the solar panel power generation will be reduced compared with summer. Distributed photovoltaic power generation is connected to the power grid. As long as the power grid has electricity, there will be no shortage of power and power outages in the household load.


4. How to clean solar panel PV modules?


Rainwater can be cleaned, solar panels do not require special maintenance, and if you encounter adhesive dirt, simply wipe it.


5. Is there a risk of electric shock when wiped with water?


Normal solar panel components are externally insulated. In order to avoid the electric shock damage to the human body caused by wiping the solar panel assembly under high temperature and strong light and damage to the components, it is recommended to clean the components in the morning or late in the afternoon.


6. Can I step on the solar panel assembly for cleaning?


The solar panel assembly has a certain load-bearing capacity, but it cannot be stepped on the solar panel assembly. This will cause hidden damage to the solar panel assembly, affecting the life of the solar panel assembly and power generation efficiency.
