Photovoltaic road surfacing
Wattway is a patented French innovation, the fruit of five years of research by Colas and INES, France’s national institute for solar energy. It is the world’s first photovoltaic road surfacing solution that generates electricity from clean and renewable solar energy, while providing a safe surface for all vehicular traffic.
Since the launch of this solar road solution, about 50 pilot projects around the world have demonstrated Wattway’s robustness. These projects vary in size, and have been developed to test multiple uses:
- Powering street lights and urban equipment (in Mainland France and the United Kingdom)
- Powering electric vehicle charging points
- Generating additional energy for buildings (in France, Reunion Island, Canada, the United States, Japan and Luxembourg)
- Supplying energy to local power grids (in France and the Netherlands)
These experiments under real and highly varied conditions have resulted in further improvements in performance and resilience for the solution. In 2019, Colas began marketing Wattway Pack, a turnkey solution that allows roadside equipment to function autonomously.
