In the beautiful mountains of Villars-sur-Ollons (VD), the 810-metre-long solar railings stretch across the entire façade of the Hotel Victoria. For the Hotel Victoria, a wish has come true: the integration of a solar solution into the existing architecture.The idea of using solar railings for the entire hotel came about when all the balustrades had to be replaced. Solar solutions on balustrades are particularly profitable in the winter months. While modules on the surrounding roofs are snowed in, the 480 bifacial modules produce a total output of 70 kWp. The future-oriented technology has an expected energy production of 15-20% of its energy. In combination with the solar park on the roof of the hotel, a considerable amount of renewable energy is generated.
