Do you know the factors that affect the service life of solar panels?

2022-02-14

With the development of the national economy, people are paying more and more attention to environmental protection. Solar panels absorb sunlight and convert solar radiation into electrical energy through photochemical effects. Compared with ordinary batteries and rechargeable batteries, they are more energy-saving and environmentally friendly. The green device has been widely used in various fields. Generally, the service life of solar panels can reach 25 years. So, what are the factors that affect the service life of solar panels? Let's get to know each other together.
1. Processing quality problems
The processing panel is generally professionally processed by the manufacturer. If the wrong processing method or unprofessional processing tool is used in the processing process. It will damage the solar panel, thus reducing the service life of the solar panel.

2. Device fault
Before the installation, the construction personnel removed the protective film on the surface of the lighting board in advance, causing things to scratch the surface of the lighting board during the construction process. Or the installation method is wrong. For example, when using a screw device on the board, do not drill holes on the board in advance. Drilling directly on the board will cause the board to break, which will also affect the service life.
3. Storage fault
After purchasing solar panels, many customers stack them at will, regardless of the storage environment. If the solar panel is placed in a humid and corrosive place, it is easy to damage the life of the solar panel.
4. Damaged solar panels
Desoldering of cells inside solar panel modules is a common influencing factor. Due to the unreasonable distance planning of the solar cells or the poor welding quality, the temperature difference between the modules during the day causes thermal expansion and contraction between the ribbon and the battery, resulting in the welding of the ribbon and the battery.
5. Working environment
With the change of time and the years of use of solar panels, there will be a lot of dust on the solar panels, which will lead to a relative decrease in the conversion power of electrical energy, so it will appear that the solar panels affect the solar cells in different environments. In addition, the shade is also one of the influencing factors. If a small part of the solar panel is blocked, it will sometimes cause the solar energy on all other panels to stop working.
