Sun-Ways’ unique approach to solar energy production involves placing one-meter-wide solar panels between railway tracks. This ingenious solution could potentially cover hundreds of kilometers of Switzerland’s railway network, generating approximately 1 TWh of solar energy annually. This output represents about 2% of the country’s total energy consumption.
The innovation goes beyond mere energy production. These solar panels can directly power :
The public electrical grid
Overhead power lines for trains
This dual-purpose functionality enhances the project’s efficiency and utility.
The installation process is remarkably efficient, utilizing a special train wagon that unrolls the solar panels between the rails like a carpet. This mechanical system can install the equivalent of 1,000 square meters of solar panels in just a few hours. Sun-Ways has filed a patent application for this unique, removable system, which is currently unparalleled worldwide.
Pilot project and future prospects
Following approval from the Federal Office of Transport (FOT), Sun-Ways is set to launch its pilot project on a 100-meter stretch of the TransN 221 line, near the Buttes station in the canton of Neuchâtel. The initial phase, scheduled for 2025, will involve the installation of 48 solar panels, each with a capacity of 380 W. This setup is expected to produce 16,000 kWh of energy annually.
If successful, this innovative approach could be widely adopted across Switzerland and potentially in other European countries by 2030. The project’s significance lies in its ability to harness renewable energy in unconventional spaces, much like the concept of photovoltaic panels in the middle of oceans.
Sun-Ways stated, “As controversies grow around the installation of solar power plants in the Alps, Sun-Ways technology could provide a relevant answer to the necessary increase in solar electricity production. Indeed, it exploits unused space without disrupting train traffic or track maintenance and inspection work.”
