Groundbreaking color gamut for solar cells

GS Integra Line Colour is a groundbreaking series of colored solar panels for roof integration.

The panels can be produced in several colors and where the color, shine and visibility of the solar cells themselves are determined by the architect.

The panels are designed to be part of the building’s climate monitor and thus form a component of the building’s architecture. The panels typically replace another plate material or glass batch and are mounted in the same façade system as these.

The panels are found in several variants, where the base model of GS Integra Line Color, consists of black monocrystalline solar cells on black background behind an iron-poor glass with anti-reflective effect.

The base panel is the basis for the coloured variants where the back of the glass in the production process is processed so that it reflects a certain part of the light spectrum. The reflected light is what creates the panel’s color.

The panels are mounted in the same working way as the remaining façade. This allows you to replace façade panels with exactly the number of solar panels that cover your needs without destroying the architectural expression.
