Who are we? esfera - your reliable provider for solar energy. Started as an architecture and real estate appraisal start-up in Bern, we have developed into a modern energy company in solar energy. Our photovoltaic systems convince not only through fast delivery times, but also through transparent processes that involve our customers at all times. Benefit from our support and always stay informed about the progress in planning, material supply and installation. With us you get the all-round carefree package!

Energie Genossenschaft Schweiz has been building photovoltaic systems for private homes, apartment blocks and housing/building cooperatives since 2012. From the system switch to the interconnection for self-consumption - we realise your desired system with passion and in (almost) any weather. In this way, we make a valuable contribution to the decentralised energy transition. Because the sun shines for free and solar energy is the right alternative. The base stations of our experienced installation teams are located in Bern, Zurich and Lucerne. Thanks to our co-operation in Graubünden, we also cover eastern Switzerland.
