Pilot Project - World premiere
Our pilot project, a 100-meter photovoltaic installation on a railway line open to traffic, was inaugurated on April 24, 2025 in Buttes (canton of Neuchâtel), marking an important phase in our development.
48 solar panels of 380W for a power of 18kWc
Other pilot projects are taking shape with SNCF in France, but also in Canada and South Korea, and discussions are already underway with potential partners in China, Australia and the United States.
As we continue our journey, we are focused on optimizing technology, developing our partnerships, and expanding our operations to make a meaningful contribution to the energy transition.
