UV preconditioning test

The UV preconditioning test is a test procedure to evaluate the impact degree of ultraviolet degradation of solar panels.
UV Preconditioning Test: set up
UV preconditioning is an irradiance test used to find out to which extend solar panels are susceptible to ultraviolet (UV) degradation and consequently performance losses. This extreme condition test, which is mostly applied during solar panel certification and research, is usually performed before the thermal cycle and humidity freeze tests.
The UV preconditioning test is performed at a temperature of 60°C ±5°C, while subjected to UV irradiation (UVB and UVA+AVB).
