SOLAR KEYMARK TESTING OF SOLAR THERMAL PRODUCTS
The Solar Keymark is the official CEN1 certification scheme for thermal solar collectors and factory made thermal solar systems. The Solar Keymark requires that the products fulfil the requirements of the European Standard series EN 12975 and EN 12976 and that this is confirmed by an accredited test laboratory. Furthermore, additional requirements such as a yearly inspection of the production line and a physical inspection of the product every second year have to be fulfilled. Although the Solar Keymark is relatively young, as it was introduced to the market in 2003, up to now (summer 2007) approximately half of all solar thermal collectors sold in Europe are already qualified with a Solar Keymark. A large number of the tests required for awarding the Solar Keymark were carried out at the Test and Research Centre for Solar Thermal Systems (TZS) located at the Institute for Thermodynamics and Thermal Engineering (ITW), University of Stuttgart. This paper describes the tests required for Solar Keymarking of thermal solar collectors and factory made thermal solar systems. Furthermore the experience gained during a large number of tests and factory inspections is reported. Finally, aspects of a further improvement of the Solar Keymark scheme rules are outlined.
