1.Sorting
Pick out good quality, complete battery pieces for string weldings.
2.Welding
String creation by interconnecting the single photovoltaic cells, then interconnection of the strings in order to create an electrical circuit.
3.Lamination layer
Automatic pick up, rotation and positioning of the strings welding to the glass with high quality encapsulant material.
4.EL Test
EL test is able to highlight information that normally is not detectable with visual inspection, power measurement or IR testing, it is possible to identify micro cracks, degradation and shunted area on cells.
5.Lamination
During this process, the encapsulant material cures and the muti-layer sandwich becomes one unit.
6.Trimming and Framing
Removals of surplus material along the sides, then install the aluminum frame around the module
