Sun-Ways Completes 11,000 Train Solar Pilot in Switzerland

SWITZERLAND – Sun-Ways, a Swiss startup specializing in railway-integrated photovoltaics, has validated its between-rail solar panel system under live traffic conditions, surpassing 11,000 train pass-overs without structural failure or safety incidents. The pilot project, conducted on an undisclosed Swiss rail corridor, used a custom deployment machine built by Scheuchzer AG capable of installing 300 meters of panels per hour. No official start date for the pilot was disclosed, but founder Joseph Scuderi confirmed to Swissinfo that both safety and electricity generation targets were met.

What Are the Technical Specifications?

The Sun-Ways system uses interconnected photovoltaic panels mounted directly between the rails on existing track infrastructure, without requiring track removal or service interruptions during installation. Deployment relies on a specialized rail-mounted machine developed by Scheuchzer AG, a Swiss railway infrastructure contractor, which lays panels at a rate of 300 meters per hour — equivalent to more than 500 panels per day. The panels feed generated electricity into nearby grids, stations, terminals, or railway facilities depending on local configuration. Exact panel dimensions, wattage per panel, total pilot installation length, and peak power output were not disclosed by the company at this stage.

Key Technical Data

Where Does This Technology Stand in the Market?

Sun-Ways enters a small but active field of companies targeting railway rights-of-way for solar generation. Bankset Energy, a Franco-Swiss firm, has been testing a comparable between-rail PV concept since 2017 and claims a generation capacity of up to 0.5 MW per kilometer of track on pilot sections in Switzerland and Germany. Italian manufacturer Greenrail offers a different approach — embedding photovoltaic cells directly into railway sleepers — with trials on regional lines in Italy and a reported output of 35 MWh per kilometer annually under optimal conditions. Sun-Ways differentiates through its mechanized deployment system, which addresses a key barrier to scaling: installation speed without traffic disruption. That said, all three approaches remain pre-commercial, and no national rail network has adopted track-integrated solar at scale. (Source: Bankset Energy, 2021; Greenrail, 2020)

Editor’s Analysis

The Sun-Ways pilot matters less for its electricity output — which remains undisclosed and likely modest — than for the operational proof it provides: photovoltaic panels can survive the vibration, debris, and electromagnetic environment of an active railway without compromising safety. Switzerland’s dense rail network, with roughly 5,300 route-kilometers (Source: Swiss Federal Statistical Office, 2023), represents a theoretical solar catchment that avoids the land-use conflicts plaguing ground-mount installations across Europe. The real test, however, will be economic: maintenance access, panel cleaning at scale, snow and ice performance in Alpine conditions, and levelized cost of electricity versus rooftop or trackside alternatives remain unquantified. If Sun-Ways can publish those figures from its next-phase deployment, rail infrastructure investors and network operators facing net-zero mandates will have a concrete benchmark to evaluate.

FAQ

Q: How much electricity can solar panels between railway tracks generate?
A: Sun-Ways has not published specific output figures from its Swiss pilot. For context, competitor Bankset Energy estimates approximately 0.5 MW per kilometer of track under favorable conditions, though actual yield depends on panel efficiency, orientation, shading, and local solar irradiation.

Q: Can trains still run normally when panels are installed between the rails?
A: Yes. Over 11,000 trains passed over the Sun-Ways installation during the Swiss pilot without operational interference or safety events, according to founder Joseph Scuderi. The panels sit below the rail head and do not obstruct wheel passage.

Q: Where will Sun-Ways deploy the system next, and when?
A: No subsequent deployment site, timeline, or commercial rollout date has been officially confirmed by Sun-Ways. The company has stated that larger-scale testing is needed before network-wide adoption can be considered.
