Over the next five years, France will install 1000 kilometres of solar roadway using Colas' Wattway solar pavement.
The collaboration between Colas, a transport infrastructure company, and France's National Institute for Solar Energy (INES) is sanctioned by France's Agency of Environment and Energy Management.
The new Wattway system does not replace the road itself, but is designed to be glued onto the top of existing pavement.
