☀️ Solar power, right between the rails
In Buttes, in the canton of Neuchâtel, Sun-Ways is testing removable solar panels installed directly between the rails of an active railway line.
One year into the pilot, more than 11'000 trains have passed over the installation, while the system has generated more than 16'000 kWh of solar electricity.🚂
The project shows how existing infrastructure could open up new possibilities for renewable energy production, while remaining compatible with railway operations and maintenance.
Supported by Innosuisse, with the contribution of partners including HEIG-VS, BKW, Canton de Neuchâtel, Canton de Vaud, GESTE Engineering, MECCAD, Romande Energie, RM Voie ferrée, Scheuchzer SA, SIG, SNCF, Transports Publics Neuchâtelois SA (transN) and Viteos.
