Solarville and Sundust have completed the realisation of a photovoltaic system for the SOMOSA model ward in Winterthur. The system with a nominal output of 63 kWp was planned by solar company Solarville and installed on the roof of the socio-educational home and adolescent psychiatric clinic.

In 2018, Sundust installed a 115 kWp PV system in western Switzerland in collaboration with Solstis. This supplies the Dr Gab's brewery in Puidoux with solar power. As brewing beer is an energy-intensive process, a large proportion of the solar power can be consumed locally. In 2023, Sundust installed an additional 202 kWp, thus utilising the entire roof area.
