Solar energy and color - Europe`s biggest Solartec facility inaugurated in Duisburg-Beeckerwerth

Since 1999, ThyssenKrupp Bausysteme has been offering a unique modular system based on steel profiles which not only provides a simple method of renovating facades and roofs but also gives buildings a new look in colors matched to their surroundings, architecture and use, while at the same time generating electricity from the sun`s rays. And the latest elements in the range of THYSSEN-Solartec® modules have added a third function: an integrated insulation layer prevents heat loss.


ThyssenKrupp Bausysteme uses UNI-SOLAR® solar cell technology for its THYSSEN-Solartec® roof and facade system. Nine thin-film layers of nanocrystalline silicon alloy are laminated together using a continuous roll-to-roll deposition process. In principle, the solar laminate consists of three stacked transparent solar cells which react to different light wave lengths. A further technical feature increases efficiency when parts of the roof or facade panels are in shadow: during the laminating process, Unisolar interconnects the individual cells with bypass diodes, so that the shadowing of individual cells does not deactivate the entire module, but merely causes a partial reduction in output.

ThyssenKrupp Bausysteme laminates the solar cell package onto color-coated steel sheet to produce light, robust and stable elements which, by contrast with crystalline photovoltaic cells, require no support structures and no heavy protective glass covers. Contractors planning to include a solar energy system in new buildings or renovation projects can save on the costs of roofing or outer facades and do not need to worry about how to fix the solar panels to the roof. The latest THYSSEN-Solartec® module variant also dispenses with the need for additional insulation: ThyssenKrupp Bausysteme now provides its Thermodach® and Thermowand® heat-insulating roof and wall elements with the solar laminate from UNI-SOLAR®. "Solartec is an interesting product which actively generates energy, passively conserves energy through insulation, provides protection against the weather and also performs a structural function," says Ullrich Finger, Managing Director of ThyssenKrupp Bausysteme.

Design perspective

The THYSSEN-Solartec roof and facade system combines ideally with the products from the "Reflections One" range of color-coated steel construction materials to give colorful highlights to architectural designs or allow buildings to harmonize with their surroundings. ThyssenKrupp Bausysteme supplies the steel profiles in matching shades from the ReflectionsOne system, while the cover strips for the solar laminate substrates can be coated in the same or different colors. ThyssenKrupp Bausysteme is thus supporting the aims and ideas of color designer Friedrich Ernst von Garnier to combine color, design and innovative solar energy into a harmonious whole.

Europe`s biggest THYSSEN-Solartec® project : Hot strip slitting line in Duisburg

The solar facade of ThyssenKrupp Stahl`s hot strip slitting facility in Duisburg - officially inaugurated on October 10 - is the perfect example of how color, technology and architecture can be integrated. Designer Friedrich Ernst von Garnier planned the facade to blend in with its surroundings: the green of the facade and the dark hues of the wave-like solar module structures allow the building to merge with the environment. Von Garnier sees no contradiction in combining color with black: "Solar cells can of course be fitted into my color designs, albeit the other way around: solar panels to date have generally been black, which is bad marketing for such a great idea. My colors provide the bridge between this technology and the people around it."
