The Solar Keymark 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 fulfills additional requirements. The Solar Keymark was developed by the European Solar Thermal Industry Federation (ESTIF) and CEN (European Committee for Standardisation) in close co-operation with leading European test labs and with the support of the European Commission. It is widely spread across the European market and beyond. Note: The difference between the Solar Keymark and the CE-mark The Solar Keymark is a quality label and the CE-mark just attests that the product fulfills minimum legal requirements according to specific European directives.
