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.
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 .
The purpose of this paper is to review different monitoring techniques of large photovoltaic (PV) plants. They can be categorized into cameras or non-cameras-based techniques which both yield complementary information.
In most of the cases, PV plant monitoring is still done using different types of voltage and current sensors which are typically attached to PV strings, rather than to a single solar panel. Thus, the detection, classification, and localization of faults still require advanced machine learning and signal processing algorithms.
Despite the above listed challenges, I-V and P-V curve measurement is the actual industry standard technique for inspecting and evaluating the performance of a solar plant. Another alternative is to deploy current and voltage sensors for online monitoring of the PV plant which are typically deployed inside the inverters.
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 .

PV Inspection
Visual inspections are important to detect major problems, like broken fuses, obvious panel issues, etc. Nevertheless this method only allows detecting few issues. As an example after a hailstorm only a few modules were exhanged at a solar power plant. Detailed investigations showed that a lot more modules were affected by the hailstorm.
