Multi-tray stringer solders up to 5000 solar cells per hour

“The enormous performance levels of Kubus enable modules to be produced at 45 second intervals,” explains Gregor Reddemann, Founder and CEO, M10 Industries AG, who will be present in San Francisco.

Up to 80 modules per hour can be manufactured by means of the new multi-tray stringer, this means at least three times as many as with previous stringers. Günter Schneidereit, Founder and majority shareholder of M10 Industries, emphasises that: “This performance is absolutely unique in the module manufacturing sector”. Kubus can also be flexibly applied. “It was designed for soldering cells with up to five busbar”, says Reinhard Willi, Founder and majority shareholder.

The Kubus stringer solders up to six solar cells side by side to form a complete cell matrix for photovoltaic modules. For this purpose the cells are transported on tooling plates, referred to as so-called trays. Up to now only single strings have been generated which have to be placed by side by side in a module. This step of the process can be entirely omitted with Kubus and therefore also the risk of cell breakage.

The biggest problem for module manufacturers is a lack of space and manpower, this is precisely where the new multi-tray stringer is able to provide what the industry requires: Kubus can be operated by a single staff member and by taking up 90m² it does not require more space than previous stringers, despite its far higher performance. “We are very excited to see what the response is to our new high performance stringer in the USA”, says Reddemann. “Our launch in Asia and Europe a few months ago has already aroused considerable interest, currently we are conducting intensive tests with materials from various customers at our facility in Freiburg.”
