Paving the way for more power from world's first solar road

03 January 2017

The world’s first solar road has been created in Normandy, France and is made of 2,880 photovoltaic panels over a 1km stretch.

The Minister of Environment, Energy and Sea, Ségolène Royal, unveiled the road on 22 December 2016. The trial site and project is part of the energy transition law which involves innovative and ambitious project achievements. 

The electricity produced by the many PV panels will be sent straight to the Enedis (French electricity provider). Daily production will differ depending on the weather but the expected annual production is approximately 280MWh. On average, the estimated electrical output will reach 767kWh per day, with peaks up to 1,500kWh per day in the summer months. 

An information panel installed near the road will indicate the immediate production as well as the total production since the installation. This panel will be powered by electricity generated via the Wattway panels. 

For Wattway’s director, Jean-Charles Broizat, this project is an important step in Wattway solar road development: “We are still on an experimental phase. Building a trial site of this scale is a real opportunity for our innovation. This trial site has enabled us to improve our photovoltaic panel’s installation process as well as its manufacturing, in order to keep on optimising our innovation.”
