Selection considerations

From cells to a packed module

Module assembly is the largest stage in this directory. A typical sequence is stringing, layup, lamination, trimming, framing, junction-box fitting, curing, testing and packing. Write the module bill of materials and line layout into your brief before comparing stations, since every machine here is configured around them.

Stringing and layup

The cell stringer class lists four machines, including the ConfirmWare AMS120CA and the Autowell AM050EH/FH; the stringer throughput guide explains how to compare their rates. Layup systems come mostly from HORAD and SC SOLAR, for example SC SOLAR's vision-guided string layup. Ask how strings are placed, checked and reworked.

Lamination and finishing

Module laminators range from the Yiheng laboratory laminator to multi-chamber production machines; the laminator specification guide covers temperature and vacuum tests. After lamination, framing equipment such as the HORAD framing system and the stations in module production lines complete the module.

Materials that go into the module

Several classes here are materials, which need qualification as well as a price: encapsulation film, ribbon and busbar, junction-box components and potting materials. The module material qualification guide explains which ageing and adhesion data to request. For acceptance of the stations themselves, use the FAT and SAT guide. Completed modules are checked with equipment in testing and inspection.

Plan the equipment scope

Define the module recipe, cell format and interconnection design before sizing assembly equipment. A complete module-line quotation should identify the responsibilities at stringing, layup, lamination and subsequent handling. Compare machine speed only after defining its output unit and test material. Describe factory space, utilities, buffers and existing conveyors, then agree how commissioning and final acceptance will be demonstrated with representative production samples.
