Project solar panel: One-of-a-kind example of a photovoltaic system combining a back-ventilated glass facade featuring Längle Glas fastening elements. The three solar panels are roughly 13 m in height and always turn with the sun. Due to this smart system the energy return is 25 % higher compared to conventional compounds.
