uv induced degradation

Fraunhofer ISE’s study uncovered critical degradation effects caused by moisture ingress and UV irradiation in accelerated aging.

In this year’s ultraviolet-induced degradation (UVID) testing, engineering advisory and test services provider Renewable Energy Test Center (RETC), has noticed that 40% of modules tested have returned with a red-flag result.

PV Tech Power spoke with Lukas Jakisch of PV testing company TÜV Rheinland about the developments and challenges facing the sector.
