Detection of acetic acid in a photovoltaic (PV) module during a combined acceleration test of ultraviolet (UV) irradiation and damp-heat (DH) is important to reveal degradation mechanism in PV module during an exposure test. We have proposed a non-destructive method of acetic acid by tin film sensors and succeeded in detection of acetic acid in PV module during DH test. In this study, we aim to detect acetic acid in PV module during combined test of UV irradiation and DH by tin film sensors.
