Solar Railways Gain Traction in Europe

WireByte Staff · July 5, 2026

Swiss start-up Sun-Ways' trial of the world's first solar railway in Switzerland has yielded positive results, with the installation of a permanent system along the railroad track now likely. The trial produced 16,000 kWh of energy in one year, despite a 10% loss due to the lack of inclination of the panels. The technology could become common in Europe, transforming railway lines into mini solar farms.

Key points

  • Swiss start-up Sun-Ways has successfully trialed the world's first solar railway in Switzerland, producing 16,000 kWh of energy in one year.
  • The trial involved 48 specially-designed solar panels with a combined power of 18 kWp, installed between active tracks in the village of Buttes.
  • The positive results have led to plans for a permanent installation along the railroad track, with the technology potentially becoming common in Europe.
  • The solar panels suffered a 10% loss in production due to the lack of inclination, but still generated significant energy.
  • Experts estimate that sloped rooftops are ideal locations for solar panels, but Sun-Ways' technology can still be effective on flat surfaces like railway tracks.

Swiss start-up Sun-Ways has made significant strides in the field of renewable energy with the successful trial of the world's first solar railway in Switzerland. The trial, which was originally planned as a three-year experiment, has yielded positive results, with the installation of a permanent system along the railroad track now likely.

The trial involved 48 specially-designed solar panels with a combined power of 18 kWp, installed between active tracks in the village of Buttes. Despite a 10% loss in production due to the lack of inclination of the panels, the system still generated a significant amount of energy, producing 16,000 kWh in one year.

The technology has the potential to transform railway lines into mini solar farms, making it a viable option for renewable energy production in Europe. Experts estimate that sloped rooftops are ideal locations for solar panels, but Sun-Ways' technology can still be effective on flat surfaces like railway tracks.

As the world continues to transition towards renewable energy sources, innovations like Sun-Ways' solar railway technology are crucial in reducing our reliance on fossil fuels and mitigating the effects of climate change.
