Solar Energy
Actions speak louder than words: St. Moritz sets a global example in nature conservation and environment protection and has realized a comprehensive energy project in an altitude between 1,170 and 3,057 metres. Hydropower, sun and wind are used consistently from the valley floor up to Piz Nair. The 'Clean Energy Tour' is the best way to explore all of the installations. The tour leads to the wind turbine facility on Munt da San Murezzan (2,666 m), the 180 ultramodern solar panels of the Corviglia funicular to Switzerland's oldest power station situated below the Lake St.Moritz using hydropower.
Facilities and installations on the mountain
- Piz Nair bottom station (2,486 metres): The photovoltaic system on the building’s facade was installed in 2003 at a cost of CHF 250,000. The 95 polycrystalline solar modules with Schott silicone cells have a 12-14.5% efficiency rate. The installed capacity is 10 kWp, average solar power 11,500 kWh per annum.
- Piz Nair summit station (3,025 metres): In 2002, CHF 321,000 was invested in the photovoltaic system of 104 polycrystalline Shell-Siemens solar cells on the building’s facade. With a 12-15% efficiency rate, they supply an installed capacity of 13.2 kWp and produce an annual average of 13,000 kWh of solar power.
- Corviglia funicular: The photovoltaic system along the railway track was installed in 2003 at a cost of CHF 367,000 and immortalizes the names of the 76 sponsors on the panels. The 180 monocrystalline solar modules by Shell-Siemens with a 12-15% efficiency rate have an installed capacity of 19.8 kWp. On average, they produce 19,000 kWh of solar power per annum.
- San Murezzan wind plant (2,666 metres): The 6.2 kW AV7 light-wind plant was installed in 2002 for CHF 223,800 and on average produces 10,000 kWh per annum.
