SKALA architecture modules have a standard format of 1.587 mm x 664 mm. Each module can also be individually customized, so the combination of standard and size-adjusted modules creates exclusive and tailor-made solar façades. Thus, builders, architects and façade designers have the greatest possible freedom for their design planning and arrangement of the building envelope.

Choose your Color

 

Due to the cell structure of the semiconductor, SKALA solar panels are distinguished by a uniform black panel surface with a fine pinstripe look. Thanks to an adapted production process and strict quality guidelines especially in the optical sector, SKALA architectural modules are dedicated for high aesthetic requirements.

By using coloured KROMATIX™ front glases, SKALA architecture modules can be produced in different colours. Contrary to conventional coloured PV modules, they use the reflection of sunlight to produce their colour. The KROMATIX™ front glass reflects the narrow spectral range of the visible light to generate the colour. The rest of the light spectrum is transferred to the module and converted into energy. All SKALA modules have the same power and performance – independently of their color.


Certified for buildings with general building approval (abZ)

SKALA is provided with a national technical approval (allgemeine bauaufsichtliche Zulassung) by the German approval body DIBt for the type of construction with an adhesively bonded mounting system. Therefore, AVANCIS is the first manufacturer offering frameless glass to glass CIGS modules with an adhesively bonded mounting system bearing also the dead weight of the modules without any mechanical support for the glasses. Thus, project specific approvals (Zustimmung im Einzelfall) are usually not required anymore for the use within the building skin.
