Every project is unique. So are our structures.

Our structures are custom-designed to suit the specific features of your site, while remaining compatible with all PV panels. They provide a solid, durable base that ensures the longevity of your PV plant.

Thanks to our range of foundation solutions and our continuous drive to innovate, we build the structure that best meets your expectations.

Our ground-mounted solutions

From fixed structures to turnkey solar farms, each product in the range meets the constraints of a particular type of project and site.

Faster, more efficient, safer. Ground screws suit all soil types, from topsoil to rock with pre-drilling, with no earthworks or excavation. They can be loaded immediately and the installation remains fully reversible.

The answer to differential settlement. Placed on ground beams, ball-joint feet are used where digging is not possible: backfilled land, engineered landfill sites, buried services. The structure compensates for uneven ground of up to 10%.

Cost-effective, quick and easy to install. Requiring no accessories, driven piles suit stable soils and offer good shear resistance, which allows wider spacing between piles. With no impact on the soil, they are removed simply by pulling them out.

Versatility

  • Our foundations adapt to all sites and soil types. Where pre-drilling is needed, no concrete is required.
  • Our structures adapt to sloping ground of up to 35°, blending in seamlessly even on complex topography.
  • Our rail system is compatible with all PV modules and gets the most out of bifacial modules.

Durability

  • Each project undergoes careful design and rigorous structural sizing to the Eurocode, ensuring the integrity of the structure throughout the plant’s lifetime.
  • Thanks to their zinc-magnesium coating, our structures withstand harsh environmental conditions (corrosion classes C3 to C5).
  • Where the ground allows, our foundations need no buried concrete at all: our structures are then fully removable and leave no trace on the site after decommissioning.

Efficiency and safety

  • Thanks to their adjustability and our rail system, our structures allow fast module mounting.
  • Access from below is safer, greatly reduces work at height and makes servicing easier throughout the life of the plant.
  • Systematic marking of the assembly bolts makes periodic checks easier.
