Analysis of Photovoltaic Panel Damage Accident

What causes solar panel re accidents?

According to , approximately 51% of the PV related re accidents is related to installation errors or poor quality of PV modules, which further causes cable faults on PV modules. On the contrary, the hot-spot effect is liable for a relatively lower percentage of the solar panel re accidents.

What happens if a fault occurs in a solar PV system?

Reduced real time power generation and reduced life span of the solar PV system are the results if the fault in solar PV system is found undetected. Therefore, it is mandatory to identify and locate the type of fault occurring in a solar PV system.

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.

What happens if a solar PV module is damaged?

Hydrogen compounds such as HF and HCL that are toxic are produced during the re accident of solar panels. In 2009, 1826 PV modules with a generation capacity of 383 kW solar PV arrays were damaged in a re accident in California, USA . In the same year, another 15 events of solar PV module related re accidents were reported in Netherlands .

What happens if a solar panel is damaged in a fire?

Hydrogen compounds such as HF and HCL that are toxic are produced during the fire accident of solar panels. In 2009, 1826 PV modules with a generation capacity of 383 kW solar PV arrays were damaged in a fire accident in California, USA .

How to avoid solar PV re accidents?

Existing approaches to avoid solar PV re accidents mainly include preventive actions. The preventive actions include array recombination and detection algorithm research. The studies illustrate the recon guration of PV modules or PV arrays, and the studies intro-duce algorithm to detect the faulty PV modules.
