      abstract     = {This case study highlights the potential of UV fluorescence
                      imaging as an emerging photovoltaic (PV) module inspection
                      tool allowing the cost and time of the field inspection to
                      be considerably reduced and opening a gateway to
                      high-throughput operation. The application of UV
                      fluorescence imaging is advanced beyond its reported
                      capabilities by combining this technique with near-infrared
                      absorption spectroscopy and electrical measurements. This
                      combined approach allows for the identification and
                      assessment of polymer backsheets and encapsulants, i.e.,
                      detection of polymer-related features (e.g., degradation,
                      corrosion) as well as other anomalies (e.g., cell cracks and
                      hot cells) with otherwise inaccessible cost- and
                      time-effectiveness. In particular, 1890 PV modules in a 2
                      MWp PV power station show critical issues, including inner
                      backsheet cracks and an insulation resistance below 1 MΩ
                      identified for $40\%$ of inspected strings and assigned to
                      specific backsheet type populations. With an average
                      throughput of 400–500 modules per hour, the present
                      approach demonstrates a large potential for acceleration and
                      cost-reduction of the PV plant inspection. It provides
                      significant insights into system performance enabling
                      proactive operation and maintenance of PV systems.},
