Unused bodies of water offer huge potential for Floating-PV systems
From disused coal quarries and mineral extraction pits to unused reservoirs, Floating-PV offers tremendous potential for contributing to the renewable energy transition across Europe.
It allays the debate over land use and allows owners of artificial lakes to make the most of their bodies of water.
A huge potential in France
The territory of France abounds in lakes from former quarries as well as water reservoirs for various uses (drinking water, irrigation, etc.). These sites, whose geographical distribution is relatively homogenous on the national level on the one hand, and which are often neglected or undervalued on the other hand, can be given a second lease of life thanks to our Floating-PV solution.
In addition, this upgrading has the advantage of being long-term, as the life span of such an installation is at least 30 years.
Floating-PV technology allows for generation of electricity in a reliable, sustainable and long-term manner with minimum impact on aquatic life and optimum grip on the water.
The experience we have gained from the deployment of large Floating-PV projects in the Netherlands has given us unique know-how that is available throughout the project life cycle, from development through construction to operation.
Floating-PV offers considerable advantages
Our Floating-PV technology has many advantages: reduction of evaporation from bodies of water, fast construction and optimised maintenance, as well as improved yields thanks to the cooling effect of the water coupled with the large surface areas used.
These advantages offset the increased installation costs of Floating-PV systems compared to ground-based solar systems of the same size.
The reduction in evaporation through Floating-PV systems can play a decisive role in the more southern regions of Europe, where water supplies are being hit hard by increasingly frequent droughts.
Thanks to these installations, owners and managers of water reservoirs can potentially obtain double benefit by collecting rental income on the one hand and preserving the water reserves of their lakes on the other. With regard to reservoirs of drinking water, our technology is certified not to produce any pollutants.
The vast possibilities of Floating-PV: significant figures for Germany
A study carried out by research institute Fraunhofer ISE shows the considerable potential offered by Floating-PV. Assuming the use of only 10% of all German man-made lakes suitable for Floating-PV (taking into account all exclusion criteria such as nature and landscape protection, recreation/leisure activities, etc.), its potential would be more than 2 GWp in Germany.
410,000 homes could be supplied with power in this way with a neutral impact on the environment. With this solar energy production, over a million tonnes of CO2 could also be saved each year.
Furthermore, the research institute Fraunhofer ISE estimates that floating solar can potentially generate 1.6 to 5.5 GW in Germany just from the lakes from lignite mines.
According to a study by the World Bank, there is a potential of 204 GWp across Europe alone, if we use 10% of the man-made freshwater reservoirs.
More water evaporates from reservoirs than is consumed by humans.
