a) EL image of a fielded module with damaged cell interconnects. Highlighted cells show an example of a cell interconnect failure Type 1 (orange), Type 2 (green), Type 3 (Red) and Type 4 (Purple). b) Boxplot showing the maximum cell temperature trend in drone altitude and cell disconnection severities compared to healthy cells. Irradiance of the inspection >800 W/m².
