How to recognise a certified product?

The products certified with the Solar Keymark shall bare the official Keymark logo.

The Keymark shall in principle  be affixed to the product itself by being engraved, pressed, moulded, printed or by any other method.  If affixing to the  product itself is not possible  or practical , it shall be affixed  to the product ’s package,  the labelling, the instructions  for use, or accompanying commercial documentation.

The marking includes an identification code of the empowered certification  body which  has granted  the Keymark. The  allocation of this  identification code  is administered by CCB  for CEN and by the members of the corresponding  Keymark scheme(s) in the CENELEC area. The identification code must remain clearly legible.

Other marks used in conjunction with the Keymark shall not create confusion with it, nor shall they  reduce  its legibility and visibility.

For more details please check the Solar Keymark Database of Certified products.


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.
