Meyer Burger Technology Ltd (Thun, Switzerland) supplied SWISS KRONO, a major player in the manufacturing and finishing of wood based products based in Menznau (Switzerland), with innovative and high-performance glass-glass solar photovoltaic (PV) modules.
In total, 406 solar PV modules in 23 different shapes were integrated in all four sides of the building. The solar facade amounts a performance of 103 kWp. The entire solar power output of the photovoltaic facade is used directly on-site.
The high-performance coating technology PERC (Passivated Emitter Rear Cell) increases the efficiency of the solar cells in comparison to conventional cells significantly. The MB PERC solar cells were further connected in the module by the innovative Meyer Burger SmartWire Connection Technology (SWCT).
The SmartWire Connection Technology connects the individual cells through a foil-wire electrode instead of the conventional two to five busbars. Thanks to the dense contact matrix the performance of the modules increases again considerably. Another advantage of the SmartWire Connection Technology is the delicate and uniform appearance of the module as part of the building shell.
The high-performance PV modules are encapsulated by glass on both sides. Thanks to the glass-glass structure the solar modules are transparent and the typical SWISS KRONO red of the SWISSCDF board underneath gleams through and has a special esthetic effect.
The attractive combination of colorful boards and transparent modules makes creative design with photovoltaic modules without loss of performance possible, Meyer Burger emphasizes.
