Why install floating solar systems ?

Simply because in many countries, there is a lack of space to install large scale ground-mount solar systems.

In parallele of small and medium scale rooftop systems in the housing and in the industry, large scale floating power plants are necessary for the solar energy to contribute to the energy mix.

Confronted to the public authorities' wish to avoid taking away large farmlands for ground-mount solar systems, we must find acceptable ecological alternative solutions.

Opportunities on inland water bodies are large in Europe and in many other countries. Quarrie lakes, dams, irrigation reservoirs, water-treatment sites or lands liable to flooding, possibilities for the installation of floating PV power plants are infinite! And most of the time, they are close to a grid connection point.

As an example, the State of Karnataka, in India, has 36 000 irrigation lakes of more than 24 acres, while farmland and electricity are missing.

Therefore, we developed and launched on the market our patent floating technology, Hydrelio©, as a reliable and cost-effective technology so that floating solar systems can represent a serious alternative to ground mounted solar systems.

Design to resist to a wide variety of natural conditions, and to produce cost-effective solar electricity, the Hydrelio© solution allows the realization of large scale floating solar systems, and thereby contribute to a better energy balance.

At Ciel & Terre, our mission is to help everyone to catch and use this precious energy. It is also our passion.
