Pioneering color gamut for solar cells

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

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

The panels are designed to be part of the building’s climate screen and thus form part of the building’s architecture. The panels typically replace another sheet material or glass section and are mounted in the same facade system as these.

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

The base panel is the basis of the colored variants, where the back of the glass in the production process itself is treated so that it reflects a certain part of the spectrum of light. The reflected light is what creates the color of the panel.

The panels are mounted in the same workflow as the remaining facade. This makes it possible to replace facade panels with exactly the number of solar panels that meet your needs, without destroying the architectural expression.
