Switzerland is once again at the forefront of clean energy innovation with a world-first project: the installation of removable solar panels on active railroad tracks. Developed by the start-up company The Way of the Sun in collaboration with the Swiss Federal Institute of Technology (EPFL), this groundbreaking system will undergo a pilot phase on a track in Neuchâtel starting in 2025. The project aims to retrofit existing rail infrastructure with solar power, providing a scalable and eco-friendly energy solution that doesn’t require additional land.
The “Sun-Ways” technology allows solar panels to be installed between the railroad tracks, enabling trains to pass without obstruction. “This marks the first time solar panels will be placed on active railroad tracks,” says Joseph Scuderi, CEO of Sun-Ways. The panels will be installed by specialized trains designed by Swiss track maintenance company Scheuchzer, with a capacity to lay up to 1,000 square meters of panels per day.
A key feature of the system is its removability, addressing a common challenge faced by previous solar initiatives. The solar panels can be easily removed for maintenance, a crucial innovation that makes solar energy viable on rail networks. “The ability to dismantle the panels is essential,” Scuderi explains, noting that this overcomes the challenges that have previously prevented the use of solar power on railroads.
The three-year pilot project will commence in spring 2025, with 48 solar panels to be installed along a section of railroad track near the Neuchâtelbutz station, which is located 100 meters away. Sun-Ways estimates that the system will generate 16,000 kWh of electricity annually—enough to power local homes. The project, which is funded with CHF 585,000 (€623,000), seeks to showcase the potential of integrating solar power into the rail network.
Despite its promising potential, the project faces some challenges. The International Union of Railways (UIC) has expressed concerns regarding the durability of the panels, potential microcracks, and the risk of fire. There are also fears that reflections from the panels could distract train drivers. In response, Sun-Ways has worked on improving the panels’ anti-reflective surfaces and reinforcing materials. “We’ve developed more durable panels than traditional ones, and they may even include anti-reflection filters,” Scuderi explains, addressing these concerns.
Weather conditions, especially snow and ice, have also been flagged as potential issues, as they could impact the panels’ performance. However, Sun-Ways is actively working on a solution. “We’re developing a system that melts frozen deposits,” says Scuderi, ensuring that the system remains operational throughout the year.
The concept of installing solar panels on railroad tracks could significantly reduce the environmental impact of energy projects. By utilizing existing infrastructure, the system avoids the need for new solar farms and their associated environmental footprint. “This aligns with the global trend of reducing the environmental impact of energy projects and meeting carbon reduction goals,” Scuderi points out.
If successful, this pioneering initiative could serve as a model for countries around the world looking to expand their renewable energy capabilities. “We believe this project will not only help conserve energy but also offer long-term economic benefits to governments and logistics companies,” says Danichet, underscoring the potential for cost savings.
In conclusion, Sun-Ways’ innovative technology could revolutionize the way solar power is integrated into transportation networks. As the world seeks scalable, sustainable energy solutions, Switzerland’s groundbreaking solar rail project could represent the breakthrough the renewable energy industry has been waiting for.
