- More than 1,130 Sunmaxx hybrid modules supply the new Vienna Sports Arena year-round with climate-neutral electricity and heat; a borehole field serves as a seasonal energy storage system.
- The installation is already delivering promising performance data, enabling largely autonomous operation and meeting the highest sustainability standards.
- A lighthouse project: The Vienna Sports Arena demonstrates how PVT technology works on a large scale – with comparatively low investment costs and maximum independence from fossil fuel price fluctuations.
Vienna/Dresden, 08.09.2025: The largest PVT system in Europe has been installed on the roof of the new Vienna Sports Arena. More than 1,130 hybrid modules from the Saxon manufacturer Sunmaxx simultaneously generate electricity and source heat for the highly efficient heating and cooling of the building – equivalent to a PVT surface area of more than 2,260 m². Thanks to cutting-edge technology, the Vienna Sports Arena is supplied with climate-neutral energy throughout the year and meets the highest sustainability standards.
While the arena has already been open for sports activities, the official opening ceremony took place on September 6, 2025. The City of Vienna provides further information on its website, including details of the opening program. Even now, the system is delivering excellent performance data and confirms the efficiency and reliability of PVT technology in large-scale applications.
In the past weeks, site visits were held for interested companies and organizations, including EQUANS Austria GmbH, the engineering firm Riebenbauer, Wiener Wohnen, project developer GreeniXCloud, and Linz Textil AG. This strong interest highlights the growing importance of future decarbonization projects in Austria and underscores the potential for further applications using Sunmaxx PVT modules.
A borehole field serves as a seasonal energy storage system and complements the installation. It ensures that the heat generated during the summer months can be stored and retrieved as needed. This enables particularly efficient operation of the overall heating system – a key element for the energy-autonomous supply of the building complex.
“The supply of the Vienna Sports Arena is a lighthouse project and shows what is possible with hybrid modules: year-round reliable electricity and heat supply, comparatively low investment costs in renewable energy, minimal servicing and maintenance requirements. Sunmaxx technology offers maximum autonomy and long-term predictable energy expenditures – without dependence on external suppliers and without exposure to fossil fuel price fluctuations,” explains Franz Ziering, Senior Sales Director at Sunmaxx.
With this innovative system, Sunmaxx PVT is actively contributing to Austria’s energy transition and once again demonstrates that renewable energy is not only ecologically, but also economically, the best solution – including for large-scale municipal and industrial facilities. Organizations interested in the project have the opportunity to visit the installation by prior arrangement.
About Sunmaxx
Sunmaxx is a leading manufacturer of photovoltaic-thermal hybrid modules and the world’s first company to offer PVT modules produced through industrial series manufacturing. The modules combine electricity and heat generation in a single product, are compatible with all common brine-to-water heat pumps, and thus enable a cost-efficient switch to renewable energy. Sunmaxx’s mission is to drive forward the energy transition by making the switch financially attractive across all application areas – from private single-family homes to industrial and commercial sites, as well as residential districts and municipal heating networks.
