Back 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.

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.
