HelioRec has deployed a 2 kWp floating solar demonstrator at Les Salins in Arles, France, to validate floating solar technology in one of the world's most challenging hypersaline environments. The project evaluates corrosion-resistant materials, mooring systems, and electrical components exposed to salt-saturated water and salt spray, paving the way for future large-scale floating solar power plants in highly saline industrial and coastal locations.
