Solar thermal

Solar panels harness the sun’s energy directly to heat water.


  • Solar thermal is very efficient: on a small surface, much thermal energy can be produced in an environmentally friendly way.
  • Solar thermal contributes to preparing thermal energy independently and in the long run, at competitive and predictable costs.
  • Most cantons and many communes support solar heat by granting subsidies and tax deductions.
  • Solar thermal plants effortlessly combine with all types of heating systems.
