The infrared thermography inspection of the PV power plant was requested and the inspection was planned to be executed in several phases.
The PV tracker system consists of 16 inverters with 66 trackers. 60 trackers have 3 combiner boxes each and 6 trackers have 2 combiner boxes each. Each combiner box is connected to 20 strings with a 19 Modules/String. The modules were 325 Wp, 330 Wp and 335 Wp Monocrystalline from SunEdison.
Adva Therm tasks were infrared thermal imaging of all PV modules (72,160 units), MC4 Connections and Module junction boxes, 198 DC Combiner boxes, and 16 Inverter rooms including DC Isolating Switches, Inverter Panels, AC Electrical Panels, Transformers and MV Switchgear.
The final and most important part was to study, analyze and prepare a fully detailed Infrared thermal report which includes all and every heat anomaly analyzed in a separate page including temperature profile and the recommended solution with repair priority that conforms to international standards.
