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

CSIT solar panel manufacturer will take you to understand solar panels

1. Processing quality issues

The processing panels are generally processed by manufacturers. If the wrong processing methods or unprofessional processing tools are used during the processing. It will damage the solar panels, thus reducing the service life of the solar panels.

2. Installation errors

Before installation, the construction workers removed the protective film on the surface of the lighting panels in advance, causing tools to scratch the surface of the lighting panels during construction. Or the installation method is incorrect, such as when using screws to install on the board, drilling holes on the board in advance without drilling holes on the board directly will cause the board to crack, which will also affect the service life.

3. Storage errors

After purchasing solar panels, many customers will stack them at will without considering the storage environment. If the solar panels are placed in a humid and corrosive place, it is easy to damage the life of the solar panels.

4. Solar panel damage

The desoldering of the internal battery of the solar panel assembly is a common influencing factor. Due to unreasonable distance planning of solar cells or poor welding quality, the temperature difference of the components during the day causes the soldering ribbon and the battery to experience thermal expansion and contraction, resulting in the soldering of the soldering ribbon and the battery cell.

5. Operating 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 cause the conversion efficiency of electric energy to decrease relatively. Therefore, the solar panels will affect the life of the solar panels in different environments; in addition, the shade is also one of the influencing factors. If a small part of the solar panel is blocked, sometimes it will cause the solar energy on all other panels to stop working. The solar cells on the solar panel are connected in series and maintain normal operation at the current level of the weaker battery. If some of the batteries on the solar panel are blocked, it will affect the normal output of other batteries.

6. Output power of photovoltaic modules

The output power of photovoltaic modules will reduce the life of solar panels. The main reason is that the output power will show a large fluctuation in the first few days of use. In the later period, due to the stable use of light and current injection into the silicon wafer, the life will also be reduced.

7. Silicon wafer quality and PN connection degree

In the early stage, due to the poor quality of the packaging materials of the solar panels used, the quality of the silicon wafers was unqualified, and the unqualified quality of the silicon wafers would directly affect the service life of the solar panels. At the same time, the PN connection degree and the purity of the silicon wafer determine the intensity of the electric energy generated by the solar panel under the same light. As time goes by, the PN connection degree will break, which will lead to a continuous decrease in luminous power. The luminous power decreases, and the loss is its service life.

8. Hot spot effect

During the use of solar street light panels, under the irradiation of sunlight, some parts of the solar panel are blocked and cannot obtain solar energy, which causes this part to be too hot and burn out to show dark spots. The most fatal thing about such hot spots is that the entire solar cell module is directly damaged, so the solar panel should be frequently maintained and cleaned.

The above are the factors that affect the service life of solar panels. If you want to extend the life of solar panels, you need good maintenance and protection.
