Initially specialized in the integration of rooftop and ground-mounted PV systems, Ciel & Terre® (C&T) has then followed the path of innovation to develop the first patented and industrialized water-based PV technology HYDRELIO®. In response to land use conflicts, this solution consists in installing PV modules on inland and artificial water bodies, converting unused water surfaces into profitable areas producing energy. Ciel & Terre has been distributing its solution and developing floating PV plants for commercial, industrial and local government institutions since 2011. Benefiting from a unique track-record, HYDRELIO® system has been installed in 25 countries, on the 5 continents.
