Launched with a large fanfare in Orne in 2016, this 1km stretch was not profitable and damaged without delivering the expected wattage.
The 1-kilometer-long road, launched today by Tourouvre-au-Perche (Orne), Ecumenical Secretary of Ségolène Royal in 2016, is part of a 2,800 m2 photovoltaic panel. It is very damaging to dark brown. At the end of May, one hundred meters were simply removed and too bad to repair.
Originally developed by Colas and its subsidiary Wattway, this future road would provide sufficient energy for the city street lamps of 5,000 inhabitants. And the revenue from the sale of electricity was to give the Orne department € 10,000. But the balance sheet, which raised about 5 million euros in three years from launch, is well below expectations.
Drop in yield
In the first year, Sun Road produced more than 50% of the 767 kWh per day. Since then, production has been steadily declining. Regarding the expected financial income, they were divided into at least two.
So we are far from the hope that the Ségolène Royal started in 2016. "The road to producing energy through the sun is actually the first big one. She said at the time. Multiply this type of project to reduce the realization cost. " She estimated that within five years, 1,000 km of roads would be covered by solar panels.
After all, Colas Wattway will continue the experiment for two new years. The road will be completely rebuilt over a short length of 400m. With slabs "25% more efficient in electricity production" The Orne department still believes. He hoped to continue the experiment and voted for € 100,000 at the end of June.
In Orne, the sun road did not keep its promise.Ouest-France.fr
