Switzerland is set to pioneer the installation of removable solar panels on active railway tracks by 2025. This innovative project, developed by the start-up Sun-Ways in collaboration with EPFL, aims to enhance energy production by utilizing existing railway infrastructure without requiring additional land.
The pilot project will begin on a 100-meter stretch near Buttes station in Neuchâtel, with 48 solar panels expected to generate 16,000 kWh annually, powering local homes. The total budget for the project is CHF 585,000 (€623,000).
According to Joseph Scuderi, CEO of Sun-Ways, a specially designed train will install and remove up to 1,000 square meters of panels per day, enabling quick maintenance and repairs. This removable feature addresses one of the main challenges of integrating solar technology with railways.
If successful, the system could generate 1 TWh of energy annually, meeting 2% of Switzerland’s total energy needs. Sun-Ways also aims to expand internationally, with plans to introduce the system in countries like Spain, Romania, South Korea, and Australia.
Critics have raised concerns about the durability of the panels and potential issues with snow and ice. In response, Sun-Ways is developing anti-reflective surfaces and solutions to melt frozen precipitation, ensuring year-round functionality.
This project could serve as a model for sustainable energy production worldwide, reducing the environmental footprint by repurposing existing infrastructure.
