Half a dozen solar roads transform the vision of infrastructure. The race for functional and sustainable projects continues its course, now the routes are presented that can not only be used to travel with our vehicles, but they can also have other functionalities, such as the production of clean energy to research the balance with the environment.

New solar road projects are planned from the United States to remote areas of China, some are already underway.

Different concepts one idea; launch solar roads.

From Japan, France, on the Nevers Magny-Cours circuit and a suburb of Toulouse, to Georgia in the United States, solar road pilot projects have been launched.

Solar roads.

The couple formed by Julie and Scott Brusaw founded the brand called Solar routes In 2006, Julie came up with the idea while trying to be aware of the environment, in which sense Scott applied his knowledge in engineering and both made sense of the vision of turning it into reality through modular solar panels. covered with tempered glass.

The approach of the creators is that in the United States there are almost 53 thousand square kilometers of roads, parking lots, driveways, playgrounds, sidewalks or bike paths and from which you can achieve good performance if you put solar panels on it. the first experiment was conducted in Idaho.

According to his calculations, his idea could “produce around 14,085 billion kWh of electricity in one year “If only 4 peak production hours are taken into account each calculated day in the northern United States, if the same proportion is taken in the south, electricity production would increase exponentially.

Wattway in Japan, France and the United States.

For nearly six months, the Colas group’s creation initiatives began to launch their pilot projects, in Japan, France and the United States, the premise of Wattway, the product of Colas, is that “A one-kilometer paved stretch of road from Wattway can provide electricity to power street lighting in a city of 5,000 people.”


Since 2016 this idea has implemented its pilot projects in France, there the starting signal was given by creating the first solar road in the world, the first kilometer of this type of road was launched in Tourouvre-au-Perche, built with Wattway. The road consists of nearly 3,000 solar panels on the sidewalk that are capable of generating clean energy to power the city’s street lights.


A few months after its establishment in France, the Wattway system arrived in the United States. 50 meters of solar highway has been installed on a road near the Alabama border. The road is part of a project presented by the Ray C. Anderson Foundation which have nearly 30 kilometers of surface to test technologies operating with renewable energies.

The project obtained recognition, the road section stood out for its premise in terms of saving lives since “It has reflective dots that use color to communicate important data to drivers in real time, such as the presence of ice (with black), thick fog, a crash ahead or erratic drivers, this with the Smart system. Road Dot formed with LED lights from solar energy and battery backup, as well as the autonomous functions enabled by a mesh network that acts in real time ”.


Wattway’s participation in Japan goes hand in hand with an American brand, the 7 / Eleven store, they presented in the Asian country nearly 60 cutting-edge technologies in pursuit of the goal of reducing the environmental impact of consumption. energy, improving the working environment for employees, among others. The pilot project was presented and launched almost six months ago.


China inaugurates the first solar highway

The Asian giant is also engaged in the race to build clean highways based on renewable energy, in this case in Jinan, the one-kilometer Chinese solar highway inaugurated in the region was carried out by the company Qilu Transportation Development Group.

Formed by several layers, one of the solar panels, the lower insulation and on the upper transparent concrete. An area of ​​5,875 square meters is covered in both lanes, as well as an emergency lane. According to the data, this system can generate one million kWh of clean energy per year.

Cycle paths can also generate clean energy.

This is the case of the Netherlands, a country which has a network of cycle paths which connects almost all of its territory. The company Solaroad installed the first in Krommenie, after one year of use the generation of 70 kWh per square meter was confirmed, enough energy for three houses, this result exceeded the expectations of its creators.
