6 FAQs about [Abnormal response of external fan of photovoltaic panel]

What are internal and external PV faults?

The internal PV faults take place inside a PV module (underneath the protective glass), on the level of PV cells, and strings. External faults localize outside the PV module protective glass and are perceived as either temporary mismatch or permanent mismatch faults.

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.

Are faults a problem in solar PV systems?

PV faults in solar PV array results significant power loss, lower reliability, very fast panel degradation, and further risk of fire (Gokmen et al. 2013 ). This chapter presents a comprehensive literature review along with a critical analysis of fault diagnosis and condition monitoring for solar PV systems. Major contributions are:

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 causes internal faults in PV cells?

Internal faults are mainly due to the manufacturer's defects: the impurities in the PV cells raw material, as well as the low semiconductor's quality used during the fabrication process, yield eventually to further complications under the operation of the PV system.

Does failure affect the reliability of solar PV systems?

The failure of the components affects the reliability of solar PV systems. The published research on the FMEA of PV systems focuses on limited PV module faults, line-line contact faults, string faults, inverter faults, etc. The literature shows that the reliability analysis method is used to evaluate different faults in PV systems.
