SolarRoad units installed in cycle path in Estampes

French road building contractor Charier has introduced the SolarRoad kit (SRK) on a newly laid cycle path in Etampes, France. Two SRK units convert sunlight to electricity and provide lighting for a roundabout near Etampes, a small commune of around 26,000 people about 50km south-west of Paris. The installation helps Charier meet sustainability objectives within the framework of the Paris Agreement. An SRK has four elements of 2.5m x 3.5m and delivers around 3,500kWh per year, which according to Solar R

Two SRK units convert sunlight to electricity and provide lighting for a roundabout near Etampes, a small commune of around 26,000 people about 50km south-west of Paris. The installation helps Charier meet sustainability objectives within the framework of the Paris Agreement.

An SRK has four elements of 2.5m x 3.5m and delivers around 3,500kWh per year, which according to 8663 SolaRoad is enough energy to power an average household for one year.

The solar panels can be driven upon but also carry cables. They contain LED lights to create lines and signage without paint and heating elements to prevent snow and ice accumulation. Microprocessors let the panels communicate with each other, a central control station, and vehicles. The glass has a tractioned surface which is equivalent to asphalt.

The technology can be applied to a business park, courtyard, square, bike path or a footpath. It can provide energy for lighting, illuminating a shop window, heating, Wi-Fi access points or - as now in Groningen, the Netherlands - a charging point for e-bikes and mobile phones.

This is more controllable and increasingly at lower cost than grid power or diesel gensets, cleaner, and often less subject to interruption. It is taking new forms as revealed in the IDTechEx Research report, “High Power Energy Harvesting 2016-2026”.

  • Dutch SolaRoad powers ahead
    May 10, 2016
    In late 2014, SolaRoad, reportedly the first solar roadway, was opened in Amsterdam, along 70m of a cycle path between two suburbs of the Dutch capital. SolaRoad consists of a cycle path constructed of concrete modules measuring 2.5m x 3.5m. In one lane, solar cells are fitted underneath a tempered glass top layer of around 1cm thickness, covered by a rough, transparent coating. The solar electricity from the road is fed into the electricity grid.
