Stringing

In this first phase the photovoltaic cells are joined to each other to form the strings using the ribbons , after which the strings are placed on the glass respecting the polarity . The most performing cells are made from monocrystalline silicon and polycrystalline silicon , and can be perfectly handled by our stringers .

Lamination

During the lamination phase the various layers in the sandwich are joined together by that automatically prepare the layers . means of hot polymerization of the EVA . The lamination machines may follow other accessory units
