Will the chromatic aberration of solar panels affect solar street lights?

I am often asked by customers why the solar panels have chromatic aberrations and whether they use C-grade films. They are very worried about the quality of the chromatic aberration solar panels. Below, our street lamp factory will explain this problem in detail.

First, why the color of the battery board is inconsistent

The color of solar panels is actually mainly affected by velvet making. The red chip is mainly caused by the low amount of texturing corrosion. If the amount of texturing corrosion is lower, the damage layer of the silicon chip will be incompletely removed, resulting in overall redness after PE coating. The so-called flower chip is caused by the excessively high amount of texturing corrosion. Generally speaking, when the amount of texturing corrosion is higher than that, the silicon chip is equivalent to the polishing treatment, and the coated cell is shiny and the grain boundary is also More obvious.

For yin and yang tablets, it can be divided into the following two situations: one is the immersion condition; the other is the deviation of the amount of corrosion between each channel. The problem of immersion liquid is caused by the level of the front and rear rollers and front baffle during the production process. When the silicon wafer enters the texturing tank, there is a time difference between the chemical liquid and the silicon wafer. In this way, the area where the silicon wafer first contacts the chemical solution will inevitably have a higher corrosion rate than the area that contacts the chemical solution later. The difference in the amount of corrosion will inevitably lead to inconsistent texture effects on the surface of the silicon wafer, and certain color differences will occur after PE coating. In order to ensure the immersion effect, the rollers and baffles of the pile making tank need to be adjusted.

The color deviation is common for polycrystalline silicon cells. For polycrystalline silicon cells, dark blue is the most common color, while monocrystalline silicon is black. Through process adjustment, the above-mentioned color deviation problem can be effectively solved.

2. Qualified solar panels also have color difference

Because of the use of coated glass, it is almost impossible to avoid this situation as long as the coated glass is used. The same batch of coated glass can't see the difference when it leaves the factory and when it is inspected. It can't even be seen after it is made into a component. It can only be found after installation, under a specific angle and light.

Another possibility is the hydrophilicity of glass. During our experiment, we found that the use of coated glass from different manufacturers has different hydrophilicity capabilities, and the difference in rain, fog, and dew is quite large, so it appears The phenomenon of different component colors. In general, it is normal for components to have a slight color difference, but if there are multiple colors on one board, the product quality is problematic. When the general photovoltaic products leave the factory, each module has undergone strict inspections, and can be used with confidence.

3. Will chromatic aberration affect the power generation and lifespan of solar street lights?

Although the use of photovoltaic arrays with inconsistent colors will affect the overall appearance, it is not easy for customers to accept it psychologically. But in fact, the simple chromatic aberration of the solar panel will not affect the power generation and lifespan. The main factors that affect the power generation are flaws, such as cracks, and the chromatic aberration is only a process problem, so it will not affect the power generation of solar street light photovoltaic modules And longevity.

In short, the chromatic aberration of solar street light panels is a normal phenomenon, and the production process cannot be avoided. However, please rest assured that any chromatic aberration will not affect the service life and power generation efficiency of solar street lights. Please everyone Buy with confidence!
