Simple and efficient ground-mounted PV installations with S:FLEX Delta Concrete
The advantages of the S:FLEX Delta Concrete:
- The Delta Concrete is designed to be used on concrete foundations with effective screw fastening
- Lightweight, material-efficient design makes the
Delta Concrete a modular and flexible system with few components - Almost all framed and frameless module types with common dimensions – especially bifacial modules – can be installed either in landscape or portrait mode
- Excellent rear ventilation ensures high yields and makes the system suitable for hot regions.
- Long service life, complete recyclability and corrosion resistance with a 10-year warranty
- System load capacity in accordance with DIN EN 1991-1-4:2010-12 (wind loads) and DIN EN 1991-1-3:2010-12 (snow loads), on request testable structural calculations for maximum safety
- We will gladly create the structural design for our customer's projects if required – the documentation we provide includes the structural analysis as well as the installation plan

The S:FLEX Delta Concrete ground mount structure is a modular and flexible system with a lightweight, material-efficient design and few components that can be planned and installed quickly. No drilling of aluminum or steel is necessary on site. Power optimisers and (micro-)inverters can be easily attached to the structure.
