The BKW FMB Energy Ltd plant on the Stade de Suisse Wankdorf consists of 5,122 solar modules covering an area of 6,540 m². These produce an energy yield of approximately 700,000 kWh per year. This is enough to supply around 200 average households with electrical energy per year. It is the world’s largest stadium-integrated solar power plant. In summer 2007 the plant will be expanded to 1.35 MWp in a second phase.
