Komax Stringer

The Xcell, a combined tabbing and stringing machine, is undoubtedly the top product in our product portfolio. We continually work to improve and expand the capabilities of this product using technologies that have repeatedly proven itself in actual practice. Our use of robotics reduces the handling time for solar cells while our ultramodern Vision Alignment System (VAS) and non-contact induction soldering make the Xcell a shining example for the industry.The Xcell product family offers a number of well-proven functions for solar cell alignment, a non-contact spray fluxing process, controlled ribbon handling for two and three bus bars, pyrometric temperature control and precise solar cell and string transport. We are constantly striving to reduce the breakage rate (a rate of less than 0.5 percent is feasible) and increase output (800 to 900 cells per hour on a back-contact machine compared to 1100 to1200 cells per hour on our conventional Xcell machines). At the same time, we want to meet our custo-mers? demands for thinner solar cells, narrower ribbon alignment, Z-bending and simplified versions requiring less maintenance.

Komax String Tester

Ideally, any problems should be resolved prior to lamination during the assembly of the solar module. Our string tester featuring reliable electro-lumine-scence technology and IV curve measurement performs precisely this task. The machine delivers a high-resolution electro-luminescent image, so the operator can reliably detect any micro-cracks. Using the IV curve measurement, the operator can instantly determine the electrical quality of the strings and record the maximum performance figures. The traceability and maximum efficiency of the solar modules are ensured by the synergy between these two physical tests and pertinent sorting/classification. The machine is available as a stand-alone module or as a full integrated additional module for our matrix product.



The string to glass layup system from Komax Solar was designed to be compatible with our universal Xcell stringer machines. The seamlessly integrated optical monitoring function for cell and string defects helps to reduce machine downtimes. The system robots are highly flexible, guaranteeing minimal changeover times and maximum flexibility in production as well as smaller overall dimensions and an improved service life. The system can accommodate lateral and longitudinal matrices (column or line arrangements).

The integrated AccuTrack  flipper function fully buffers the strings, allowing the Xcell stringer to produce continuously. The reliability string deposition handling system removes the checking strings fully automatically, returns reworked strings to the process using special handling units, and has a function for loading/unloading during system operation.


An absolute cutting-edge technology of our equipment is the Laminator STAR 4000 DD plus  with approx.24 sqm total laminations area. This laminator can laminates 12 standard modules each (1m x 1.6m ) at the same time per cycle. Thus, a capacity of up to 100 MW per year is achieved with minimal space demand.
