(PDF) Infrared Thermal Images of Solar PV Panels for Fault
In [36], the authors have verified that high accuracy fault identification is possible by performing thermal imaging analysis of PV panels and using radiation sensors.
One of the significant challenges is the fault identification of the solar PV module, since a vast power plant condition monitoring of individual panels is cumbersome. This paper attempts to identify the panel using a thermal imaging system and processes the thermal images using the image processing technique.
Utility-scale PV power plants are impacted by common solar panel faults, which can be observed as hotspots in thermal imagery. Algorithms that detect solar panels and hotspots, if present, can benefit the utility-scale inspection process. Preliminary results demonstrate the opportunity and challenges of thermal imagery for PV.
RELATED WORK A. Thermal Imaging Thermal imaging collected through infrared (IR) cameras has emerged [25-32] as a powerful technique for PV fault detection. These IR thermography cameras have recently become accessible to consumers and professionals due to advances in manufacturing and the relaxation of foreign military-use concerns.
