A solar railway trial in Switzerland has produced 16,000 kWh of energy in one year, leading to potential expansion across Europe. This system may transform railway lines into solar farms, capable of generating significant renewable energy.
In Switzerland, the start-up Sun-Ways completed a one-year trial of the world's first solar railway, installing 100 meters of photovoltaic panels along active tracks in Buttes. Initially planned as a three-year experiment, the success has prompted consideration for permanent installations along the railway.
The solar installation consists of 48 panels with a combined power of 18 kWp and has produced around 16,000 kWh of electricity. This amount of energy is comparable to the average energy consumption of a fully electric UK home. If implemented across Switzerland's 5,317 kilometers of railway, Sun-Ways estimates potential annual production of around 1 TWh, contributing to 2% of the country's total energy consumption.
The solar panels on railway tracks lose about 10% efficiency due to their mounting angle. There are concerns regarding safety, including the risk of micro-cracks in panels, potential fires, and driver distractions from reflections. Addressing these challenges is crucial for wider deployment.
The successful trial in Switzerland could set a precedent for other European countries looking to integrate renewable energy with existing infrastructure. Transforming railway lines into solar energy producers aligns with Europe's push towards sustainability and carbon reduction.
