New solar absorber coatings are developed and used in advanced collector designs with improved efficiency. The operation temperature as well as the stagnation temperature as the main durability load for the absorbers were increasing during the past due to these innovations. Especially the highly selective new coatings have to suffer by these stronger loads. The service life estimation procedure developed in the framework of research activities of the IEA Solar Heating and Cooling Programme (Task 10 and Working Group Materials in Solar-Thermal Collectors) were based on load profiles for less advanced absorbers and collectors and did not take into account the impa...
