Sonnwende GmbH

Sonnwende plans photovoltaics for single and multi-family homes as roof-mounted or in-roof systems. Beyond the classic roof, the company also fits PV into carports, noise barriers and balcony railings. For storage, salt-based systems without lithium are available alongside the usual solutions. Installation is done by in-house teams, and the company also handles the administration, including the funding application.

Heat pumps and wood heating run through sister company LWS in Therwil, alongside charging stations with energy management and hot water solutions. Sonnwende operates in Basel and the surrounding municipalities, with projects in places such as Riehen, Allschwil and Bottmingen. The company is a member of Swissolar and listed as a solar professional. The content is in German.
