Photovoltaic solar module manufacturing

A photovoltaic solar module is a set of electrically connected solar cells. Its purpose is the generation of electric current. Solar cells can be manufactured from different materials. Mostly mono-crystalline or poly-crystalline silicon is used. For thin film solar cells, thin semiconductor layers are deposited on an inert substrate, mainly glass. For the manufacturing of solar cells various equipment is necessary.
Quite often, single solar cells do not produce enough electrical power. Therefore many PV cells are combined in so called photovoltaic solar modules and weather proof mounted between glass plates. This assembly can be done inline and fully automatic. The manufacturing process consists of several steps:

tabbing and stringing    
Tabbing and stringing solar cell string
Pfeil Layup and bussing
Solarzellenfeld Layup on the glass and interconnecting, bussing
Electric Inspection Pfeil
Electric inspection voltage current characteristic
Pfeil EVA sheet and back sheet loading
  EVA sheet and back sheet loading
Laminator Pfeil
Laminating equipment  
Pfeil Module framing
  Edge taping and module framing
Module packing Pfeil
Testing and Packing  

We can offer you turn-key solar module assembly lines in a variety of different capacities.

Due to the modular design the layout is flexible, within limits. After a successful start with the smallest size, 30 MW, it is easy to expand to 50 MW or 100 MW, or even bigger.
