Switzerland successfully tests solar-powered railway

A groundbreaking "solar railway" project in Switzerland has successfully completed its initial tests, attracting interest from multiple countries. The innovative system, developed by startup Sun-Ways, proposes powering trains by integrating solar panels directly into the railway tracks.

Tests conducted on a 100-meter section of track near Bütt, Switzerland, have yielded promising results, prompting regional authorities to consider permanent installation. Over its operational period, 48 panels on the test section generated approximately 16,000 kilowatt-hours of energy, comparable to a household's annual electricity consumption.

While the system faces challenges, such as the optimal angle for solar panels and potential panel contamination, developers are addressing these issues. They claim energy loss due to the lack of tilt is only 10 percent and propose using brushes on rolling stock to clean the panels. Concerns about fire risks from micro-cracks and glare affecting train drivers have also been raised by the International Union of Railways.

Despite these concerns, Sun-Ways has already secured a cooperation agreement with an Italian company involved with the national railway infrastructure operator, Rete Ferroviaria Italiana. The startup is also in discussions for solar panel installations in South Korea and is negotiating with firms in the Netherlands, China, India, and Singapore, highlighting the global potential of this renewable energy solution for transportation.
