About Helion Energy AG

Helion Energy AG operates at Spühlstrasse 4 in St. Gallen in the fields of heating, HVAC and renewable energy. The company covers a broad spectrum: from solar energy and photovoltaics to heating installation, charging infrastructure for electric vehicles and servicing of solar systems.

This results in a coherent offering centred on a household's own energy supply: as a solar energy equipment supplier and heating contractor, heat generation and power production can be combined, while the EV charging station integrates mobility. The solar energy system service area also provides support and value retention for existing installations.

Helion therefore addresses homeowners and clients in St. Gallen and the surrounding area who want to approach solar, heating and e-mobility as a coordinated overall system. Further information at helion.ch.
