Hydrelio, floating photovoltaic solar panels to be installed on bodies of water

Hydrelio, floating photovoltaic solar farm system

Hydrelio is a system for developing floating photovoltaic solar farms in a simple, affordable, easily scalable and sustainable wayaccording to its developers, the French company Ciel & Terre.

The innovative floating solar platform Hydrelio makes it possible to install standard photovoltaic solar panels on large water surfacessuch as reservoirs, lakes, irrigation canals, ponds, among others.

It’s an easy-to-install, cost-effective alternative to ground-mounted solar farms, in areas where you don’t want to waste it. Aquaculture farms, wastewater treatment plants, cooperative irrigation reservoirs, among others, are companies and organizations that can benefit from this technology, taking advantage of the synergy created between the solar installation and the water. of the tank.

Hydrelio® is modular, scalable, adaptable to most photovoltaic panels and compatible with many types of water bodies.

The solution aims to solve the problems of ground and roof mounted systems. It is particularly interesting in areas where land is scarce and/or particularly expensive, for various reasons: the need to preserve agricultural land, in areas with a high population density, in small or island countries, in countries with large mountainous area.

Hydrelio also tries to solve the problem of unused water surfaces for a positive purpose such as the production of green energy.

Additionally, floating solar power generation and power consumption can approximate grid infrastructure, as Hydrelio can be placed on many water surfaces.

The technology reduces solar exposure of water, thereby limiting water evaporation and also reducing algae growth and eutrophication which deteriorate water quality. It is particularly interesting for irrigation basins, dams or drinking water reservoirs, for example. In addition, solar cells are more efficient due to the natural cooling effect of water.

In addition to savings in the field, there are other advantages:

  • Thanks to the cooling effect of the water in the solar panels, these systems produce more energy than ground-based systems of similar size.
  • By shielding the water from the heat of the sun, these platforms prevent evaporation, thereby increasing the return on investment.
  • They improve water quality and reduce maintenance costs by reducing algae growth.
  • Aerators and water circulation devices, powered by solar energy, can be integrated into the system, which oxygenate it and keep it in good condition, saving on chemicals and maintenance. They call this technology Aquago, and it was developed by a subsidiary of the company.

Obviously this system does not require excavation work or the use of concrete. The floats are made of HDPE plastic, are 100% recyclable and easy to remove. They can be used without health problems, even in tanks containing water intended for use as drinking water.

The innovative Hydrelio floating solar technology has already been put to the test, and Its estimated lifespan is about 30 years.. Since 2011, the system has been tested in a pilot project in France, where it has demonstrated its efficiency and proper functioning.

They are currently developing several projects, one of 12 MW and another of 4 (in the south of France), which will provide clean electricity to thousands of homes without wasting precious agricultural land. Other floating solar projects are in the execution, study or design phase in different parts of the world.
