Solar-Paved Highway


Wattway is a patented French innovation that is the fruit of five years of research undertaken by Colas, a world leader in transport infrastructure, and the INES (the French National Institute for Solar Energy). By combining road construction and photovoltaic techniques, Wattway pavement provides clean, renewable energy in the form of electricity, while allowing for all types of traffic.


Wattway debuted with a pilot site in France in 2015, and through a partnership with Hannah Solar, The Ray will be the first pilot in the U.S. A 50-square meter-installation of Wattway solar paving panels that will be installed at the West Point Visitor Information Center adjacent to The Ray in the fourth quarter of 2016.


Wattway can be applied directly over existing paving, which gives it the potential to be an energy-generating retrofit for highways like The Ray. Wattway can potentially feed electricity into the grid, and can power public lighting and road signs and signals in cities, towns and remote areas. It can also provide electricity to electric vehicle charging stations (bikes, motorbikes and cars), positive energy buildings, and transport infrastructure.
