The Solar Keymark was developed by ESTIF, now Solar Heat Europe, and European Committee for Standardisation (CEN) in close co-operation with leading European test labs and with the support of the European Commission.

It is a voluntary third-party certification mark for solar thermal products, demonstrating to end-users that a product conforms to the relevant European standards and full fills additional requirements.

The Solar Keymark is used in Europe and increasingly recognised worldwide and is solely dedicated to:

  • Solar thermal collectors (based on European standard series EN 12975)
  • Factory made solar thermal systems (based on European standard series EN12976)
