New Wattway pilot site in Nabonne
66m² of solar road were installed on a carpool area in Narbonne (Highway A9, exit 38). The goal of the installation is to provide a clean energy, stored an then used to power roadside equipment locally (here, the light for the pedestrian path).
Wattway wins a trophy at the CES Las Vegas 2019!
The wattway autonomous generator was presented at the “francophone village”. Among 80 start-up and companies, Wattway won the silver Smart City award as well as the second “Grand Jury Prize”.

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.
X2
By the year 2050, global energy needs will have doubled.
10%
Roads are only occupied by vehicles 10% of the time.
20m²
20 m² of Wattway panels can supply the electricity requirements of a single home.
The advantages
ENERGY
PERFORMANCE
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).
GRIP
AND RESISTANCE
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.
INSTALLED DIRECTLY
ON EXISTING PAVEMENT
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.
The Colas Group
The Colas Group is a world leader in the construction and maintenance of transport infrastructure.
Striving to meet the challenges posed by mobility, urban development and environmental issues, Colas has built a reputation since it was founded in 1929 as an innovative, responsible Group.
After years of research in a partnership with the INES, Colas is now able to combine its expertise in roads with that of photovoltaic technology, paving the way to Wattway, the world’s first photovoltaic road surface.

Colas wins a Climate Solutions Award for the Wattway Solar Road
As part of the COP21 United Nations Conference on Climate Change, Colas has won a Climate Solutions Award for the Wattway Solar Road. The selection jury, whose members include experts in resources and climate matters, has honored Colas with a Favorite Award in the Mitigation – Large Enterprise category.
Organized by Ademe, C3D, le Crédit Coopératif, Orée, Solutions COP21, The Shift Project and World Efficiency, the Climate Solution Awards are given out to highlight the best solutions for alleviating and/or adapting to climate change.
