The objectives of this project are the analysis of aging processes and the development of accelerated aging tests for solar thermal collectors and their components. The exposition of collectors in extreme climatic conditions enables the verification of these procedures and the development of degradation models.

The cooperative project by the Fraunhofer Institute for Solar Energy Systems ISE (coordination) and the University of Stuttgart’s Institute for Thermodynamics and Thermal Engineering (ITW) runs for a period of four years. It is funded by the German Federal Ministry for Economic Affairs and Energy (BMWi) / Project Management Jülich (PTJ) and supported by the participating industrial partners.
