Aging and lifetime investigations#
When developing new key optical components, such as reflectors, reflector systems and absorbers, long-term stability must be taken into account, as must tests conducted to check these qualities using accelerated aging. Working alongside our Test Lab PV Modules, we carry out the following investigations, which also all feature optical quality testing.
- Temperature cycling tests
- Humidity/frost and humidity/heat tests
- Hail tests
- UV tests
Where test standards are available, we test the materials and components according to these guidelines.
We also investigate aging and soiling patterns of the reflective material used in concentrating collectors caused by outdoor exposure. We currently expose reflectors to outdoor conditions in Freiburg (temperate climate), in the Negev region in Israel (climate in which solar thermal power plants are typically found) and on Sicily (maritime climate).
