2.75 MWp above the biological treatment stage: Germany’s largest solar folding roof is being built in Stuttgart
Germany’s future largest solar folding roof is currently being built at the Stuttgart-Mühlhausen main wastewater treatment plant.
World-first axis solution for the Grazerfeld solar folding roof
At Grazerfeld, the real innovation of the solar folding roof lies in its support structure: to span the circular tanks, dhp Technology developed a new axis solution that is being implemented in this form for the first time. It demonstrates how the solar folding roof can adapt even to complex existing infrastructure.
Structural Challenges & Project Management at the Frankfurt-Niederrad Wastewater Treatment Plant
The implementation of the solar folding roof at the Frankfurt-Niederrad wastewater treatment plant was heavily influenced by the existing building structure.
HORIZON becomes HELIOFLEX® – Energy that adapts to every situation.
HORIZON becomes HELIOFLEX®. With this change, we are evolving our brand and creating a clearer positioning that is easy to understand internationally. Our proven technology remains unchanged.
Digitalization as the key to an efficient PV solution
dhp Technology optimizes the control of its HELIOFLEX® solar folding roof with Schneider Electric and Baffy. Thanks to EcoStruxure Automation Expert, systems can now be configured twice as fast, are more independent from third-party providers, and come with new smart features.
High-Quality Lightweight Steel Construction for the World’s Largest Solar Folding Roof
When innovative technology meets well-thought-out design, flagship projects are created – such as at ARA Thunersee. Here, dhp Technology has implemented the world’s largest movable solar folding roof. A key element: the lightweight steel construction. The delicate yet extremely load-bearing structure enables reliable energy generation above existing treatment basins, impressing with quality, efficiency, and sustainability.
«The glass-free solar panels, stainless steel moving parts and galvanised support structure hold up well over the filled septic tanks. The roof retracts and extends as it should and covers 20% of our electricity needs, as expected.»
