Twenty-one square meters of monocrystalline solar panels have been installed on the terrace of the panorama restaurant "Le Kuklos" on the Berneuse Mountain above Leysin. Each square meter produces on the average 169 kW of energy per year, which yields an annual production of 3,550 kWh. The energy powers the motors that rotate the second level of the restaurant on its axis. In addition, running hot water is also heated with the help of the solar panels. The adjoining nature trail offers diverse information on renewable energy. Interactive posts offer a vivid experience of the topic.
