New solar folding roof system in Davos increases winter electricity production

Solar folding roof system in Davos increases winter electricity production

The “energy city” Davos is relying on the power of the Davos sun and is taking a further step towards energy self-sufficiency. Above the Davos wastewater treatment plant, the first alpine solar folding roof system has been installed at an altitude of over 1,500 metres above sea level. This means that the Davos wastewater treatment plant will in future produce electricity for its own consumption in a decentralised and independent manner. This also in winter.

The Davos solar folding roof has 252 kWp installed PV capacity and will produce approx. 255,000 kWh of electricity per year. Of this, the Davos wastewater treatment plant will consume around 93 percent itself. Due to the high altitude and the generally low temperatures, solar plants in the mountains produce particularly efficiently. Because snow reflects the sunlight, the conditions for photovoltaic systems in the Davos Landwasser Valley are ideal.
