Photovoltaics are still running after a year under Swiss trains
Solar boss reckons challenges are regulatory, not technological
It is just over a year since a pilot project to install photovoltaics on a railway line kicked off. According to the CEO of Sun-Ways, the company behind the scheme, the challenge was not so much technical as regulatory.
The project, a 100-meter photovoltaic installation on a railway line open to traffic, was inaugurated on April 24, 2025 in Buttes, Switzerland. It's fair to say it went well; the 48 solar panels wedged between the tracks have generated more than 19 MWh to date.
According to the company's CEO, Joseph Scuderi, more than 11,000 trains have passed over the solar power plant without incident. There has been no impact on railway operations or solar generation.
It's a novel idea – use the space between rails for solar power generation. While the angle of the panels might not be ideal, the losses would...
