World record solar fence realized in Basel
The world's longest solar fence with a length of over one kilometer is being built along the Reinach - Münchenstein streetcar line. The lighthouse project combines renewable energy generation with urban infrastructure. A pioneering step towards sustainable urban development.
A new safety fence was required as part of the BLT streetcar line route renewal. Instead of a conventional solution, the project focuses on functional added value. A vertically installed solar fence. The combination of safety infrastructure with bifacial photovoltaic modules makes double use of existing areas without additional land consumption, a decisive advantage in urban areas.
High performance along the rail
A total of over 400 high-performance bifacial modules will be installed, which can absorb solar radiation on both sides and convert it into electricity. The predicted maximum output is 194 kWp. The integration takes place on a specially developed frame system in basalt gray, which blends harmoniously into the cityscape. This system was developed in cooperation with the company Next2Sun, which specializes in vertical photovoltaic solutions.
Sustainable energy from the fence
The project is being implemented in stages. While the first construction phase of the fence has already been completed, the installation of the photovoltaic modules is now beginning. The project is being realized as part of a collaboration between Solarzaun GmbH, BLT and Alpsteinzaun Tor AG. The integration into the existing streetcar renovation construction site enabled smooth implementation.
Research and prospects
The project is also being supported by the scientific community. Professor Hartmut Nussbaumer from the ZHAW sees the solar fence as a pioneering model for urban energy solutions. Particularly noteworthy is the energy production at times of day when conventional PV systems, such as those on roofs, work less efficiently. The system therefore complements conventional photovoltaic strategies and improves the seasonal security of supply.
Model with a signal effect for cities worldwide
With the world’s longest solar fence, Basel is setting a strong example for the intelligent combination of mobility and energy infrastructure. The project combines technical innovation with urban integration and is expected to serve as a model for similar approaches in other regions. For specialists and managers in urban development, energy planning and infrastructure management, this model offers concrete suggestions for a sustainable future in urban areas.
