As any energy production system, photovoltaic (PV) installations have to be monitored to enhance system performances and to early detect failures for more reliability. There are several photovoltaic monitoring strategies based on the output of the plant and its nature. Monitoring can be performed locally on site or remotely.
Thermal imaging sequences were processed to emphasize defect signals. Optical stepped thermography combined with post-data processing is a fast and effective way to discover solar panel faults. In Natarajan et al. (2020), PV cells are classified into two categories using a simple machine-learning technique based on image processing. Faulty .
Anomaly detection is indispensable for ensuring the reliable operation of grid-connected photovoltaic (PV) systems. This study introduces a semi-supervised deep learning approach for fault detection in such systems. The method leverages a variational autoencoder (VAE) to extract features and identify anomalies.
Additionally, using the same MS, we propose a recursive linear model to detect faults in the system, while using irradiance and temperature on the PV panel as input signals and power as output. The accuracy of the fault detection for a 5 kW power plant used in the test is 93.09%, considering 16 days and around 143 hours of faults in different .

Line-to-line fault detection for photovoltaic arrays based on multi-resolution signal decomposition and two-stage support vector machine.
What are the performance metrics for a photovoltaic fault detection system?
(False Negative): it occurs when the photovoltaic system presents a fault and the detection system does not signalize it. Based on this, one can define the following performance metrics for the proposed fault detection system: E = T N T N + F P . 6. Fault Classification
What is fault detection in PV systems?
Fault Detection In general, fault detection for PV systems is based on the modeling of the system in order to compare the results from modeling with real-acquired data, indicating a fault event every time the difference between modeling and acquired data is above some predefined threshold [ 16 ].
How does automatic PV failure detection work?
Authors in introduce an automatic PV failure detection based on statistical correspondence between potential causes of failures, results of simulation and the extraction of parameters of the PV system model using Matlab/Simulink.
Can neural networks detect faults in photovoltaic systems?
A fault diagnosis technique for photovoltaic systems based on neural networks is proposed by (Chine et al., 2016 ). Two different algorithms are developed to detect and classify eight different faults. The results demonstrated that this technique is highly capable of localizing and identifying the different kind of faults.
