Ciel & Terre’s scope of expertise

Let’s start our tour of the floating solar island, shall we ? We are currently on the bank, standing between the grid connection point and the FPV array. Before starting, let us present you what is the scope of Ciel & Terre on a floating solar project from FPV plant engineering to Operation and Maintenance. Download our leaflet to learn more about our floating solar expertise.

Cable way

We include the layout of the cable ways into the Floating solar plant design. It allows an easy and quick cable management to connect the FPV island to the grid connection point. Find out more about our cable ways solutions :

About the maintenance walkway

As the floating expert, we pay attention to every innovation and to the changes which appear on the market. Our Hydrelio® aiR range has been developed to be compatible with the wider scope of PV panel sizes.
Their functions ?

  • Ensures connection with the main floats
  • Provides sufficient spacing between panels adapting to the environmental conditions
  • Used as a maintenance walkway for the system

Hydrelio® aiR 1440


Secondary floats range size : Available from 685 to 1700mm

Hydrelio® aiR Optim


Secondary floats range size : Available from xxx to xxxmm

Electrical device supports

We have created special systems to have a smart installation of the inverters and junction boxes on the plant. Our solutions are adapted to our Hydrelio® floats. They enable the electrical devices to fix safely on to the floating PV plant and enhance cable management and increase electrical efficiency.

In addition to our floating solar panels technology

  • We have developed a floating barge for you to install your inverters or transformers and to minimize the electrical losses related to the routing of the cables to the banks.
  • We have also created a wave breaker which reduce significantly the waves around the floatovoltaic plant, providing an optimized environment four you floating solar farm.

Easy maintenance pathway

To ease the maintenance and operation activities, we have created a maintenance float. This specific float optimizes the comfort, the stability and the buoyancy of the floating solar plant.
