SolarWelt utilizing teamtechnik stringers in brand-new 400MW German assembly plant

• New Germany-based PV module supplier SolarWelt has actually signed a volume order with Freiberg-based PV stringer expert teamtechnik to allow the manufacturing of monocrystalline half-cut PERC (166 x 83 mm cells) with 9 busbars into high-efficiency modules at its planned facility in Thuringia.

teamtechnik claimed that SolarWelt, as sister business to existing module manufacturer Heckert Solar, bought an undefined large number of its TT2100 generation plus layup systems to produce the high-efficiency modules.

The Stringer TT2100 was stated to have actually been specifically made for high-precision processing of 9-busbar PERC cells that are soldered via exceptionally tiny pads (roughly 1.0 x 0.7 mm) on the front and rear of the cells. The obstacle was to position nine slim ribbons accurately onto the small pads at broadband, according to teamtechnik.

Danny Bönisch, project supervisor for SolarWelt said, "We recognize with teamtechnik production systems at Heckert Solar and we know that they will allow us even to surpass our very own premium requirements."

SolarWelt is anticipated to begin manufacturing in the first quarter of 2021 with a manufacturing capability of around 400MWp.
