To meet your needs.

Years of innovation in floating solar


Tests done on parts and components

We can adapt to a variety of pond types with reliable and bankable products.

Our solutions are designed based on our continuous R&D involvement, which started years ago. They are tested by trustful partners, and they are used in more than 250 floating solar projects around the world.

Our teams analyse your project, and they select the most appropriate technology and floating PV plant configuration considering your needs and the conditions of your pond site.

Hydrelio®, more than a product…

We systematically design the floating PV plant and the anchoring plan along
with supplying our products.

Anchoring by Ciel & Terre


Ancrage conventionnels - Ciel&Terre
Saha Park, Thailande – 480 kWp
Hybrid anchoring (bank and bottom) | Deadweights
Along with our anchoring design
expertise, we master anchoring
installation in numerous countries.
We are able to set up any
anchoring systems, bank as
well as bottom.
Ancrage Conventionnels - Ciel&Terre
Anhui CECEP, Chine – 70 MWp
Bottom anchoring | Screws
Ancrage conventionnels - Ciel&Terre
Don Sai, Thailande – 1.9 MWp
Bank anchoring | Percussive earth-driven anchors


Parabolic mooring line

Ancrage spécifique - Ciel&Terre
We apply our innovative spirit
to anchoring too so that the solutions we
propose are the most adapted to your
site’s constraints.

We pioneered the parabolic mooring
system, which we can design and
install for your floating PV project
when needed and applicable.

Pillar anchoring

Ancrage Spécifique - Ciel&Terre
We have developed an innovative
anchoring solution for dry ponds and
ponds where the water level
regularly fluctuates.

This pillar anchoring system
guarantees an optimal FPV plant lifetime
on such ponds.

Does your pond present specific constraints, like particular wave or snow loads, or it can dry out? Discover how to remove these constraints with our solutions.

Your electrical station on water

We offer you the floating barge solution to safely install inverters and transformers on water.

Thanks to this system we minimise the electrical losses due to the cable distance between the FPV plants and the banks.

Our test policy

Our solutions are innovative and designed for optimised performance. Their reliability expresses itself via the numerous projects in which they are used around the world, and it is proven by the tests they pass.


We have established a Research lab to continuously enhance the performance of our floating solar solutions.
We validate products, evaluate projects and test products under development. The tests assess the relevancy and the longevity of the solutions we offer you.
We have developed specific test benches.

  • Tensile bench with ‘Heating and Cooling’ chamber
  • PFS (Panel Fixation System) Bench
  • Wave Fatigue Bench
Product Lab - Ciel & Terre
Banc de traction avec chambre climatique Ciel & Terre

Tensile bench with ‘Heating and Cooling’ chamber

The mechanical strength of the product is evaluated
under different environmental conditions to understand and
replicate wind / load parameters present at
every floating solar site.

Banc PFS Ciel & Terre

PFS (Panel Fixation System) Bench

The fixation system is a critical factor for the life of a floating
solar plant. To check its precision, the system is analysed for
maximum tension, compression, and fatigue loads.

Test Lab Ciel & Terre

Wave Fatigue Bench

Wind and waves are the biggest loads that will affect a
floating solar plant. Using the know-how related to our
wave fatigue bench we accurately evaluate our products’
resistance to these loads.

We also have test sites.

Bassin de test - Ciel&Terre

Test site in France

They enable us to evaluate our product developments under real site conditions.

Bassin de test - Ciel&Terre

Monitoring site in Japan

We monitor some real-scale projects to study different points of consideration for floating PV plants.

Our technical partners

Our floating solar and anchoring solutions are validated by qualified companies and labs.
