Getting rid of ballast

For the first time, our VarioTwin 4.0 will installed without any additional ballast – on the flat roof of the new car wash plant “Dream Carwash” in Arnsberg, Sauerland, Germany. Of course, the system meets the highest expectations in terms of functionality and safety under these conditions, too. Yet, our VarioTwin 4.0 is an attractive alternative for light weight constructions and foil roofs.

350 VarioTwin 4.0 will be mounted on the flat roof of Dream Carwash in Arnsberg in combination with the RENOLIT Alkorsolar system. The Renolit rail system which is the carrier of the VarioTwin 4.0 will be welded on the foil roof. Of course, Renolit has been approved by the site supervision and tested up to storm forces of 200 km/g

Thanks to the combination of the two systems, you can overlay foil roofs without additional ballast which would affect the roof’s bearing load.

The Sonnet Vertriebs GmbH which will install the system is a regular customer of the Solardirekt Energy GmbH & Co. Kg.

We are looking forward to the start of the construction works on Thursday, June 8, 2018, and to the results. If you are interested in more information, please, get in touch with Peer Haase on or on the phone +49 5971 8040526.
