The largest DAS Energy-Kalzip project to date has now been successfully completed after several months of work and is already delivering clean solar power.

KALZIP GmbH and DAS Energy worked together successfully on the roofs of the company and production halls of the German company Trumpf in Ditzingen.

The flexible DAS Energy PV modules were able to impress in terms of performance, lightness (3.3 kg/m²) and shape.

The modules were adapted to the desired size for the architecturally well-integrated solar roof of the German tool manufacturer Trumpf.

The challenge of this project was to design the special roofing elements from the Kalzip company on the Trumpf production halls efficiently and aesthetically and to achieve the highest possible yield.

The roof landscape, consisting of a slightly pitched gable roof and a butterfly roof, each with a 5° gradient, was fitted with over 10,000 DAS Energy PV modules (12x2 Project PV modules) covering a total area of ​​15,200 m².

An output of almost 1,140 kWp was installed on the entire roof area, which ensures environmentally and economically sustainable energy generation.

The semi-flexible solar modules consist of high-efficiency monocrystalline silicon cells embedded in patented glass-fiber composite materials. The project PV module 12x2 with the dimensions 2035 x 357 x 2 mm has an output of 120 Wp. The only 2 mm thin modules are flexible, extremely stable and weatherproof.

DAS Energy GmbH develops and produces its ultra-light and flexible PV modules in Wiener Neustadt (Lower Austria).

Thanks to the high-quality, transparent ETFE (ethylene tetrafluoroethylene) front sheet, the PV modules are not only dirt-repellent and scratch-resistant, they but also make use of the so-called "lotus effect".

Further projects with Kalzip are already being planned. DAS Energy is grateful for the good cooperation and is looking forward to the next joint projects.
