Solar Keymark – Solar thermal power collectors and systems


Solar Keymark is a voluntary third-party certification for solar thermal power collectors and systems, recognised Europe-wide.
The mark was developed by ESTIF (European Solar Thermal Industry Federation) and by CEN (European Committee for Standardisation) with support by the main test laboratories and the European Commission.
Certification of solar thermal collectors and systems according to standards UNI EN 12975 (part 1), UNI EN ISO 9806 (formerly UNI EN 12975 (part 2)) and UNI EN 12976 (part 1 and 2) guarantees actual compliance of the components of a solar thermal plant with European standards as well as their quality, safety, functionality and is a binding condition to obtain the incentives provided for installation of a thermal solar system according to the New Thermal Account.
Standard UNI EN ISO 9806, which replaces UNI EN 12975 – part 2 – has introduced updates to the test procedures for assessing durability, reliability and safety for fluid heating collectors (glazed, unglazed and hybrid).
All products certified after 1 January 2015 must comply with the new standard and the existing certificates concerning the previous standard may be renewed as long as the test report is no more than 10 years old.

ICIM, recognised for issuance of the Solar Keymark since 2003, is now one of the 13 European Certification Bodies and caters for manufacturers and dealers who wish to place their products on the market with the Solar Keymark.
ICIM provides services for certification and issuance of the Solar Keymark for products:

  • solar collectors (glazed, unglazed, vacuum pipes, modular);
  • solar systems;
  • hybrid thermal-photovoltaic panels (PVT);
  • solar concentrators.
