The massive growth of PV farms, both in number and size, has motivated new approaches in inspection system design and monitoring. This paper presents a review of imaging technologies and methods for analysis and characterization of faults in photovoltaic (PV) modules.
Gallardo-Saavedra et al. reported that the time needed to complete an inspection of a PV site with a capacity of 3 MW, with 17142 modules, was 34 working days, and to post-process and analyze the results another 26 working days .
Starting from well-known mathematical models of PVMs, Pinceti et al. propose an innovative approach to correlate the results of a thermographic inspection with the power losses and the consequent income reduction, as a valid tool for supporting decisions about the maintenance actions on PV plants .
This test evaluates the current-voltage characteristics of PV strings. The heat generation of PV modules is inspected by the IR thermal camera. By knowing the deviation of the temperature, problems like the bypass diode in the PV arrays can be detected. Additional inspections are also available for inspections outside Category 1 and Category 2.
The conventional approach to PV module inspection is to use a hand-held infrared sensor and perform visual inspection in-situ by a human operator. The main disadvantages of this method, when applied to a large-scale PV power plant, are that it is time-consuming and costly .
Thus, a proper monitoring of the PV panels is required. The current state of the art is that, despite lot of algorithms and hardware which were developed so far, online monitoring of PV systems is still in the prototyping stage and yield only limited fault information before a mature and standardized metrology can take place.
