The world’s first stretch of solar road has opened in France.

Some 2,880 photovoltaic tiles have been installed on 1km of road at Le Gué à Pont, west of Paris on the RD5 between the southern exit of Tourouvre and the crossing with the N12. The installaton is by Colas-owned Wattway.

It has been officially opened by French minister for the environment, energy and sea Ségolène Royal and was funded by the ministry.

The energy produced by this road will be returned to the network with an expected annual production of 280MWh. On average, the estimated electrical output will reach 767 kWh per day, with peaks of up to 1,500 kWh per day in summer.

The section of road will be monitored to see how it performs under average traffic of cars and trucks.

France eventually aims to install 1,000km of solar roads.
