Information

1. Common problems of battery slices
The reason for the network crack on the surface of the module is mainly due to the external force of the battery during the welding or handling process, or the expansion of the battery after a sudden high temperature in a short period of time without preheating at a low temperature. The mesh crack will affect the power attenuation of the module, and the occurrence of debris and hot spots after a long time will directly affect the performance of the module.

2. Ribbon, Bus Bar and Flux FAQ
Welding will lead to the delamination of the welding tape and the cell in a short time, which will affect the power attenuation or failure of the module. Over-welding will cause damage to the internal electrodes of the cell, which will directly affect the power attenuation of the module, reduce the life of the module or cause it to be scrapped.
3. Common problems of glass, silica gel and profiles
The peeling of the coating layer on the coated glass surface is irreversible. The coating process in the module factory can generally increase the power of the module by 3%, but after two to three years of operation in the power station, it will be found that the film on the glass surface is peeled off, and it is unevenly peeled off, which affects the glass transmittance of the module, reduces the power of the module, and affects the entire square. burst power. This kind of attenuation is generally difficult to see in the first few years of operation of the power station, because the error of attenuation rate and irradiation fluctuation is not large, but if compared with the power station without film stripping, the difference in power generation can still be seen.
