The Solar Keymark
The main quality label for solar thermal
The Solar Keymark was created to certify solar thermal products of high quality at European level. The aim is to reduce trade barriers and promote the use of high quality solar thermal products in the European market and beyond.
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 fulfils additional requirements. The Solar Keymark is used in Europe and increasingly recognized worldwide.
