6 FAQs about [Photovoltaic module explosion expected accident]

What causes fire incidents involving photovoltaic (PV) systems?

Currently the number of fire incidents involving photovoltaic (PV) systems are increasing as a result of the strong increase of PV installations. These incidents are terrible and immeasurable on life and properties. It is thus very important to understand the causes, effects and how prevent the occurrence of incidents.

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 .

Are PV cells a fire hazard?

The prerequisite of reaching the full provision is further research on PV fire and its impact on the overall building fire safety while the current studies are at the stage of looking into the performance failures and faults of PV cells rather than the PV building systems.

How to prevent solar PV fire accidents?

Existing approaches to avoid solar PV fire accidents mainly include preventive actions. The preventive actions include array recombination and detection algorithm research. The studies [40-50] illustrate the reconfiguration of PV modules or PV arrays, and the studies [51-78] introduce algorithm to detect the faulty PV modules. FIGURE 9.

What happens if a PV module catches a fire?

PV modules power generation systems are mainly installed on the rooftop, which can be threatened to fire incident. If its catches by fire, care should be taken in fighting the fire, and it should not respond similar to others conventional sources of electricity.

What causes a PV module fire?

Factors lead to PV module fire accidents. In PV modules, series connected cells are usually used. Some PV cells suffer from partial shades from surrounding objects, such as fallen leaves, dust accumulation, and bird drops while other PV modules do not, hot spots may be produced due to non-uniform power generation status amongst the PV cells.
