ASTANA Expo 2017 – Future Energy
From June 10 to September 10, Astana Expo 2017 will host an international event designed to appeal to the international community’s sense of responsibility about this year’s theme: Energy of the Future. For the occasion, a Wattway photovoltaic panel will be presented in the main exhibit pavilion. Four theme-based pavilions will also be open:

  • “World of Energy” reveals possible solutions to ensure development of more sustainable energy in the future with the help of physics and science experiments
  • “Energy for the Future”illustrates the concept of energy saving and energy efficiency.
  • “Energy for All”presents the mechanisms of access to energy for the planet’s inhabitants
  • “My Future Energy” focuses on personal responsibility for efficient and economical use of energy

First ever US Wattway solar road installed in Georgia
The first Wattway experimental site in the United States was inaugurated in December 2016 in Georgia. Launched at the time of Paris COP 21, Wattway is currently evaluating many applications on experimental sites around the world. The Ray Foundation, the Georgia Department of Transportation and Wattway have partnered together for the first installation in the United States on the stretch of road known as “The Ray C. Anderson Memorial Highway”. The 18 mile section of Interstate 85, Georgia, is dedicated to testing and creating the highway of the future.
Fifty square meters of Wattway solar panels have been installed at the Georgia Visitor Information Center in West Point, GA which will be powered by energy generated by Wattway.

The first kilometer of Wattway Solar Road in Normandy
On Thursday, December 22, 2016, the first major Wattway Solar Road project was inaugurated by Ségolène Royal, French Minister of the Environment, Energy and the Sea.
This Wattway trial section, which is made up of some 2,880 photovoltaic panels, is located on Route RD5 between Tourouvre south exit and the intersection with Route N12 in le Gué-à-Pont. The electricity produced by the solar road will be sent out to the Enedis* network (*French electricity provider). The innovative and ambitious project is perfectly in line with France’s energy transition law.

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.
20
20 m² of Wattway panels can supply the electricity requirements of a single home.

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).

adhérence et résistance

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.

Pose sur chaussée existante

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.

Its applications

to power public lighting in a city of 5,000 inhabitants.

Towns and cities

In urban areas, the need for electricity is growing. How to produce and how to transport the energy we need? These are some of the most important environmental issues of our times. With Wattway, electricity can be produced and used locally. Wattway fits perfectly into the smartgrids* model that will be used to design the cities of tomorrow.

In cities, Wattway’s applications are endless: public lighting, urban furniture, buildings, homes, signs, etc.

Isolated, off-grid areas

In some remote areas, it is sometimes difficult and costly to supply the infrastructures and villages with electricity. Without having to undertake any major construction work, Wattway provides developing countries with a new, durable solution for short circuit renewable energy.

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.
