In general, due to the presence of bubbles inside the solar panel module, especially along the edges of the frame and ribbon, the solar panel delamination is very obvious, even the surface ETFE, PET can be directly ripped off. Thus, even without technical means, it is easy to identify the layered components.
If you can't get a closer look, you can look at the resistance of the solar module. When the resistance is too low, the inverter won't start. Once there is a delamination problem, there is no way to repair it, only all replacement, otherwise there may be fire and other phenomena for a long time.
Generally, there are several reasons for delamination:
First when laminated panels, the temperature of the lamination is not enough, and laminated didn't have enough time, some of the solar panel widget layer of pressure and temperature is enough long time, solar back may be covered by a little deformation, not function damage, but some customers don't accept the deformation degree, will reduce the laminated time and temperature, but the harm is very big, And a major cause of solar panels catching fire.
The use temperature of solar panels, if the temperature is too high, will cause the EVA inside to melt again, leading to delamination, generally in summer, so pay attention to the summer temperature of solar panels. It is better to ask the merchant when buying.
Why do solar panels fall apart?
As mentioned before, the solar panel has a multi-layer structure (surface material +EVA+ solar cell +EVA+ back material), encapsulation agent, here usually refers to EVA (epoxy resin glue). After laminating machine, the different layers of EVA are bonded together.
The solar panel laminator operates in less than 20 minutes, at a temperature of around 140 degrees Celsius, and in a vacuum. This is very important and the tuv approved solar cable eliminates any air content within the solar module and guarantees a high quality product.
During lamination, EVA changes from solid to liquid and finally precipitates as a gel at the end of the cycle. In fact, the different layers of the assembly will be sealed together and guaranteed by the manufacturer for 25 years of power output, which is determined by the percentage of EVA gel. There are different factors that can be responsible for the low proportion of gels: the raw materials used, how those materials are transformed, and the manufacturing process. The quality of laminates is determined by gel content, which is measured by chemical testing. A well-organized production facility can be tested in-house.
