The core activity of Solargenossenschaft Lyss (SGL) is the planning, construction and operation of photovoltaic systems (PV systems) for the generation of solar power. The company offers its members the opportunity to invest in a sustainable energy transition and thus align energy production in the region with the future. SGL focuses on the construction of PV systems on suitable roof surfaces, such as the roof of the fire station or the municipal workshop in Lyss, and sells the produced solar power to its members or into the distribution grid.
