In Basel, we were allowed to create a PV roof on an already existing foundation with a 15m long span. Here, too, the motto was to equip already built-up areas with photovoltaics before building up untouched areas.

Our Single Axis Tracker produces 64.1 megawatts of peak power, enough electricity for 20,000 Egyptian households. But it is already reportedly the country's largest solar field, with 200,000 panels that adjust to the sun's position and an area of about 50 soccer fields.

In the summer of 2022, we were able to implement a special project for the Federal Office for Building and Regional Planning (BBR) in Berlin. The customized PV Bikebox offers space for 36 bicycles. All parking spaces have their own locker that securely locks the bikes and private items using a pin code. In order to charge the e-bikes with green electricity, a photovoltaic system was integrated on the roof.

The bus parking lot of the municipal transport company of Seville (Tussam) has space for about 400 buses. We were assigned to design and build a roofing. The city and the management of the operating company Tussam attached great importance to the architecture, the acceptance of the population and the employees. Therefore, we developed a lightweight tubular steel structure that allows moment-free load transfer from the roof to the foundation. The force fluxes created by the applied loads change from compression to tension and vice versa. The profit of the construction comes from the fuel savings and the generation of electrical energy.
