“…Moreover, the algorithm complexity is O(mn(log(m) + 1)), where the logarithmic term comes from the ordering required in line 9 in Algorithm 1. Notice that in other research papers such as [7,32] or specialize reviews such as [8,23], the computational complexity of the solutions are not addressed.…”

“…Imaging methods are currently expensive and time consuming, whereas electrical characterization is cheaper and more flexible [24]. The latter methods also can be further split into several branches: signal processing and statistical methods (e.g., [8,25,26]), i − v curve characteristics analysis (e.g., [27,28]), power losses analysis or efficiency analysis (e.g., [17,29,30]), current and/or voltage measurements (e.g., [31,32]), and artificial intelligent methods (e.g., [9,33,34]). The diagnosis algorithm implemented in this work is based on the IF-THEN rules presented by the authors in [35] and follows the diagnosis branch based on current-voltage measurements.…”

“…The fault diagnosis of photovoltaic array can be carried out by analyzing the variation of time series waveform. The authors of [19] deployed the voltage sensor by distinguishing the odevity of the number of the photovoltaic array string, meanwhile, formulated the positioning rules for each fault to achieve accurate location of faults. Abd El-Ghany et al [20] installed a diode in each photovoltaic string and adopted the change rate of instantaneous voltage and current to detect the fault of photovoltaic system.…”

“…PV modules are often installed in the harsh outdoor environment and thus tend to suffer several kinds of faults, causing unexpected safety issues, power losses, and even fire hazards 4 6 . Actually, not only will the transport of the PV modules but also their storage and unsuitable handling during installation lead to performance reduction or potential faults 7 . Dust is an unavoidable factor that affects solar PV module performance and is considered as one of the major factors that contribute to the formation of hot spots 8 , 9 in a PV module.…”
