Glass-glass solar modules

There is a distinction between two solar module types: glass-film and glass-glass modules. In the glass-glass type, two panes are combined into one solar module. They become laminated safety glass and therefore have unique properties.


Front and back glass in combination with durable encapsulation material protect the components from vapour penetration. In the «neutral zone» between the panes, the cells remain stress-free (no compression or bending) which reduces the occurrence of so-called micro cracks. This results in a potential lifespan of over 50 years.

Free design scope, high durability and stability characterise this solar building material. All glass-glass modules can be designed freely. Glass-glass modules are manufactured in Deitingen SO, Switzerland.

Areas of application

The use ranges from facades and railings to roof-integrated and rooftop applications.

Type of installation

Glass-glass solar modules can be installed both with or without frames. The mounting systems FAST, LEVEL and NICER are especially suitable for the integration of glass-glass solar modules.

Non-glare solar glass

Particularly anti-glare surface structures are used.
