Swiss solar panels on railway tracks survive 11,000 trains, generate 16,000 kWh

Swiss startup Sun-Ways installed 48 removable solar panels along 100 metres of active railway track in Buttes in 2025. After more than 11,000 trains passed over them, the panels have generated over 16,000 kWh; a three-year pilot is assessing the safety and practicality of producing renewable electricity from railway space.
