Three brands – one strong unit
The Business Unit Energy combines the expertise of three specialized brands:
- Form-Tec is responsible for project business with planning, engineering services, and comprehensive support tailored to the individual requirements of our customers
- Gebhardt-Stahl supplies highly precise roll-formed steel profiles – the stable foundation for efficient solar substructures.
- Van Zelst offers customized bending and stamping parts that meet even the most complex technical requirements.
Each brand presents itself with a clear role and focus – together they form a strong network for future-proof photovoltaic solutions.
Innovation in focus: The tool-free frame system
A special highlight was the presentation of our new tool-free mounting system. This solution enables particularly fast and easy installation – completely without additional tools. It saves material, effort, and reduces installation time by up to 20%. A true efficiency gain that has impressed both national and international customers alike.
Shaping the future together
Our trade fair appearance was not only an eye-catcher but also a strong statement of our attitude: We stand for progress, quality, and collaborative partnerships. Intersolar 2025 demonstrated what is possible when we join forces – and how, as the Gebhardt Group, we actively shape the future of the solar industry.
