A solar path in the Netherlands has proved successful and will now be trialled with heavier kinds of traffic.
The 90-metre long SolaRoad cycle path near Krommenie was initially opened in October 2014, built by a consortium including the Province of Noord-Holland and Strukton Civiel.
Project developers say solar roads can create renewable power to power public lighting, traffic management systems, households and electric mobility, without taking up space or visually polluting an area.
Tests have revealed the top layer is crucial to the path’s success – it must be transparent to efficiently generate energy, as well as be strong and skid-resistant.
SolaRoad will now be extended onto two roads exposed to heavy traffic, to study how it behaves under different loads and to learn about the impact of solar pavement on daily road management and maintenance.
The Province of Noord-Holland is providing €2.7 million (£2.4m) in funding for the pilot project.
