Why do PV panels need a fault diagnosis tool?
Continuous determination of faults must be carried out to protect the PV system from different losses, so a fault diagnosis tool is essential to the reliability and durability of the PV panels. Fault detection and diagnosis (FDD) methodologies include three main approaches as shown in Fig. 3.
What are the fault detection methods for PV system?
The fault detection methods for the PV system are classified in the visual (discoloration, browning, surface soiling, and delamination), thermal (thermal extraordinary heating), and electrical (dark/illuminated I - V curve measurement, transmittance line diagnosis, and RF measurement).
How to identify a fault in a PV panel?
The faults in the PV panel, PV string and MPPT controller can be effectively identified using this method. The detection of fault is done by comparing the ideal and measured parameters. Any difference in measured and ideal values indicate the presence of a fault.
