Europe’s infrastructure is embracing the renewables boom, with one company determined to transform the continent’s railway lines into mini solar farms.
Last year, Swiss start-up Sun-Ways unveiled the world’s first-ever solar railway after rolling out 100 metres of photovoltaic (PV) panels in between active tracks in Buttes, a village in the Val-de-Travers district.
Originally planned as just a three-year trial, the railway was fitted with 48 specially-designed solar panels with a combined power of 18 kWp.
However, the positive results yielded just one year into the trial mean the installation of a permanent system along the railroad track is now likely, Euronews Earth has been told.
Solar panels are often installed at a specific angle to ensure they absorb the maximum amount of sunlight throughout the year.
In Spain, for example, the optimal angle for efficiency is between 30° and 35°. According to a 2022 study published in Science Direct, a 34° tilt on solar panels in the Iberian Peninsula resulted in annual production losses lower than one per cent.
It’s why sloped rooftops are naturally convenient locations to install panels – while garden fences, balconies and flat roofs will generate less energy in comparison.
Sun-Ways estimates that the loss of production due to the lack of inclination of the railway panels is only around 10 per cent. Still, in one year, the project has produced around 16,000 kWh.
To put this into perspective, this is roughly the same amount of energy an average UK home uses, where everything is powered by electricity (such as heating, hot water, lighting and appliances).
In theory, solar panels could be rolled out across the entirety of Switzerland’s 5,317 kilometre-long railway network – covering a size equivalent to 760 football fields or more than 50,000 times the trial coverage.
Sun-Ways estimates that this has the potential to produce around one Terawatt hour (TWh) of electricity every year, around two per cent of the country’s total energy consumption.
Transforming railway tracks into renewable energy hubs is no easy feat, and comes with its own set of unique challenges.
One of the biggest concerns, previously expressed by the International Union of Railways, is that the panels could suffer micro-cracks, lead to a higher risk of fires and distract train drivers due to reflections.
Sun-Ways has tackled these issues by building more resistant panels than what would be installed on rooftops, fitted with an anti-reflection filter.
Built-in sensors also ensure they work properly while brushes attached to the end of trains can remove dirt from the panels’ surface.
When asked if there were any issues within the first year of operation, Sun-Ways told Euronews Earth that “the plant worked perfectly” and that it didn’t have to carry out any “special maintenance”.
“For this first pilot project, the electricity is sent directly to the grid,” the company adds. “But we are already working to reinject the electricity produced with Sun-Ways power plants directly into the railway substations or into the train traction line.”
Following its successful trial in Switzerland, Sun-Ways has just signed a collaboration contract with an Italian business partner who is in contact with the country’s national railway infrastructure, Rete Ferroviaria Italiana.
Plans to launch a pilot project in the coming months will be unveiled soon.
Sun-Ways has also received government approval to install another solar railway in South Korea, while discussions are underway with Dutch, Chinese, Indian and Singaporean companies.
