Swiss energy firm Axpo has built a snaking wall of solar panels on Switzerland's longest dam to maximize green energy generation throughout the winter months.
The Lake Muttsee dam in the central Swiss canton of Glarus is almost 2,400 meters above sea level and surrounded by snow-capped peaks, which Axpo’s AlpinSolar project team describes as a crucial benefit.
"One of the qualities of alpine solar plants is that especially in winter they produce up to three times more electricity than a comparable facility in the midlands," said Jeanette Schranz, communications lead for renewables at Axpo.
