The concept

As the energy transition becomes reality, imagine a road able to harvest solar energy and produce energy locally.

The world’s 1st ever photovoltaic road surface
Wattway is a patented French innovation that is the fruit of 5 years of research undertaken by Colas, world leader in transport infrastructure, and the INES (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.

A new vision for roads
Wattway produces electrical energy without overtaking farmland or natural landscapes, and contributes to increasing the share of photovoltaic electricity in the energy mix, both in France and worldwide.

The advantages

performance énergétique


Pavement is only occupied by vehicles some 10% of the time. Imagine the solar resources of this surface area, facing the sky.
20 m² of Wattway panels provides enough electricity to power a single home. (Source ADEME/CEREN 2014 – average French household for 1,000 sun hours/year – not including heating).

adhérence et résistance


How to reconcile the fragility of photovoltaic cells and the robust structure of a road? Wattway is composed of cells inserted in superposed layers that ensure resistance and tire grip. The composite material is just a few millimeters thick, making it possible to adapt to thermal dilation in the pavement, as well as vehicle loads, a guarantee of durability and safety.

Pose sur chaussée existante


If Wattway is so revolutionary, it’s also because of the way it is installed! No need to rip out the existing structure, Wattway can be applied directly on the current pavement, without any need for civil engineering work.
