Solar Keymark Certification

What is the CE markding of solar collectors?



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 is used in Europe and increasingly recognized worldwide.

The Solar Keymark is a CEN/CENELEC European mark scheme, solely dedicated to:

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

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 the main quality label for solar thermal products and is widely spread across the European market and beyond.

 Who can certify ST products?

Certification Bodies empowered by CEN Certification Board for issuing Solar Keymark licenses. These Certification Bodies ensure that the products and their manufacturers comply with the requirements of the Solar Keymark Certification Scheme.

The empowered Certification Bodies require from the costumer testing according to:

  • EN 12975-2: Solar thermal systems and components - Solar collectors
  • EN 12976-2: Solar thermal systems and components - Factory made systems

From recognised Test Labs, i.e., Test Labs that comply with the requirements of the Certification Body and are entrusted by this to carry the according to the relevant EN Standards and the SK scheme rules.

 What is the CE marking of solar collectors?

CE marking is a mandatory conformity mark for products placed on the market in the European Economic Area (EEA). The letters "CE" stand for "Conformité Européenne" ("European Conformity").

Main 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 fulfils minimum legal requirements according to specific European directives. In general the CE marking is not a quality mark but this depends on the directives regulating specific industrial goods.

By including the CE marking on a product, a manufacturer ensures that it conforms with the essential requirements of the applicable EC directives.

 CE-marking related to Construction Product Directive (CPD)

CE-marking of solar collectors related to the Construction Product Directive (CPD) is under preparation. 

More specific info related to collectors.

 CE-marking related to Pressure Equipment Directive (PED)

As solar collectors are pressurized, the question arises if they are touched by the regulations of the EU pressure equipment directive (PED).
