Solar Keymark – Quality for Europe

Logo Solar Keymark

Solar Keymark is the official European quality hallmark for solar collectors and systems. It was introduced by the European Committee for Standardization CEN. The Solar Keymark shows the purchaser that a product conforms to the relevant European standard and is regularly monitored by an independent organisation.

The Solar Keymark certification is issued based on the following:

  • Testing to the relevant European standard
    EN 12975 for collectors, EN 12976 for compact systems.
  • Manufacturer quality management
    The manufacturer should operate an appropriate quality management system (at least ISO 9001). Audits are carried out in every case.
  • Sampling
    Collectors and systems submitted for certification are taken from the production line by an independent test laboratory.
  • Regular monitoring of manufacturer’s products and quality management system
    Both products and production processes are regularly monitored by a test laboratory.
    Any changes to products should be reported.


For transparency purposes the results of all tests carried out are published on: www.solarkeymark.org

In the framework of a project supported by the Solar Keymark Certification Fund, SPF offers the Argus newsletter. This newsletter provides up-to-date information about all changes in the European Solar Keymark database.
