Floating Solar: The New Alternative to Traditional Solar

Established in 2006 as a renewable Independent Power Producer (IPP), Ciel & Terre has been fully devoted to floating PV solar since 2011. The company pioneered the first specific and industrialized system – named Hydrelio® – to make solar panels float on water, with criteria such as cost-effectiveness, safety, longevity, resistance to winds and waves, simplicity, drinking water compliance and optimized electrical yield.

Today, Ciel & Terre is manufacturing its Hydrelio® system in 8 countries: Japan, France, South Korea, China, Brazil, Taiwan, the United States and United Kingdom. With a track record of more than 200 MWp using the Hydrelio® system, Ciel & Terre is expecting to increase this number to 330+ MWp in 2018.

Along with the supply of the Hydrelio® system, Ciel & Terre also provides a full range of services to its customers. From site identification to financing solutions, with full PV plant engineering, with anchoring design and installation, with float and panels assembly on the water surface, and operation & maintenance services. As the niche industry originator and market leader, Ciel & Terre is investing more than 5 % of its turnover in R&D to continuously improve its system to reduce costs and adapt to every market needs.
