What is the Solar Keymark?

1 Introducing SK

The Solar Keymark is a voluntary third-party certification mark for solar thermal products, owned by CEN/CENELEC.

Every certified product is in full conformity with the relevant European standards and fulfils additional requirements to assure constant quality. This level of quality is maintained by initial type testing and by regular controlled of the products and their production sites by independent inspectors. Consumers and authorities can fully rely on the certified products.

For these reasons the Solar Keymark is the basis for most European supporting schemes and it is also increasingly recognised or adapted worldwide.
