Solar folding roof in Davos increases winter electricity production

The "energy town" of Davos relies on the power of the Davos sun and takes another step towards energy self-sufficiency. The first alpine solar folding roof system has been built above the sewage treatment plant Davos at an altitude of over 1,500 metres. This will enable the Davos sewage treatment plant to produce decentralised and independent electricity for its own consumption in the future. This will also be possible in winter.

The Davos solar folding roof has 252 kWp of installed PV power and will produce approximately 255,000 kWh of electricity annually. WWTP Davos will consume around 93 percent of this itself. Due to the altitude and the generally low temperatures, solar plants in the mountains produce particularly efficiently. Because snow reflects sunlight, the conditions for photovoltaic systems in Davos' Landwasser Valley are ideal.
