The line consists of the ergonomically designed Tabber Stringer with the patented Hybrid Soldering technology which ensures less than 0.2% breakage. The machine has the capability to solder very thin PV solar cells such as Mono, Poly, Bifacial, PERC, HJT and high efficiency solar cells without mechanical and thermal stress. Machine is equipped with 2 High Resolution Camera – One to check the alignment and second camera to check the centering and to detect any broken cell before soldering. The equipment is capable of handling 4,5 and 6 bus bar commercially available cell.

The high throughput Tabber Stringer is supported by 6 axis ROBOT to pick the strings from the belt and place it on the Glass & EVA pre-loaded on the automatic conveyor belt. The Pre-programmed Robot picks up the string and moves through the camera for better alignment of the strings on the glass. The clockwise / anticlockwise direction of the string is done by the settable recipe on the Robot. The Glass is loaded on the automatic conveyor belt by the Glass handling system.

The bussing is carried out on an Motorised conveyor equipped with continuity tester, Soldering station. The bussing station is followed by a visual inspection table for checking any foreign particles, alignment etc.

The pre-lamination Electroluminescence (EL) Tester supplied with the input roller conveyor and output reject conveyor detects Micro cracks, Contamination, Sintering Defect, Defects of Solar cell material (Debris, Cracked, Broken Gate, pollution), Defects from the Welding Process (Weld, De-Solder, Broken Fingers), Mix Different levels Cells sorted wrongly. The equipment performs DARK IV Test and is supplied with two High Resolution camera with acquisition time of less than 20s. The equipment is capable of testing Mono, Poly and Thin Film Modules
