The use and maintenance of solar panels directly affect the service life of solar panels, the operating cost and efficiency of solar power generation systems. The maintenance of solar panels is the best way to ensure the good operation of photovoltaic power generation systems.

Monocrystalline solar panels are outdoors for a long time, are blown by wind and sunburn, and the surface is covered with dust, which will prevent the solar panels from absorbing sunlight. Therefore, the solar panels should be cleaned and cleaned regularly, and exposed connections should be checked and maintained regularly.

PV module should regularly check and maintain the following items:

1) Observe regularly.
When the dust on the surface of the Photovoltaic panels is gray and the original aquamarine panels cannot be clearly seen, it should be cleaned up in time.
In order to avoid electric shock damage and possible damage to solar cell modules caused by wiping the solar cell array under high temperature and strong light, the Solar modules should be cleaned in the morning or late afternoon. The glass surface of the solar cell module should be cleaned with a soft brush, clean, mild water should be used, and the cleaning intensity should be small to avoid damage to the glass surface. For parts with coated glass, care should be taken to avoid damaging the glass layer. If it is dry ash, it can be washed with feathers.

2) In the event of strong wind, heavy rain, hail, heavy snow, etc., check whether there is any covering on the surface of the solar cell array, and take measures to protect the solar cell array to avoid damage.
If there is snow on the solar cell array after snow, you can use soft objects to push the snow down. Be careful not to scratch the glass on the surface of the solar cell module. The solar cell module has a certain load-bearing capacity, but you cannot step on the solar cell module to clean it. , It will damage the solar cell module or affect the life of the solar cell module. Generally, it is recommended not to wait for the thick snow to be cleaned to avoid excessive freezing of the solar cell module.

3) Regularly check whether the solar cell array connection wire and ground wire are in good contact, and whether there is any looseness or falling off. Regularly check the packaging of the solar cell components. If water is found to be leaked into the package, repair or replace it in time.

4) The solar cell module is not afraid of contact with water, because the solar cell has been sealed and installed under the tempered glass, and the back is laminated with EVA, so there is water on the outside, and no water will enter the cell that comes out, even the battery inside. Don't worry if the film gets into the water, because the characteristics of the solar cell can be short-circuited. At most, there is no power output when the short-circuit occurs. After the short-circuit disappears, it can be used as good as before.
