6 FAQs about [Howang Photovoltaic Inverter Explosion Accident]

What happened to the three inverters used for the solar plant?

The three inverters used for the solar plant. Maintenance teams quickly identified the source of the fire. Indeed, traces of wear on the cables that connect the modules to the transmission terminals had been observed since October 2021.

How to reduce re accidents in large scale applications of solar panels?

In order to minimize the risks of re accidents in large scale applications of solar panels, this review focuses on the latest techniques for reducing hot spot effects and DC arcs. The risk mitigation solutions mainly focus on two aspects: structure recon guration and faulty diagnosis algorithm.

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.

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.

How many solar panel related re accidents are reported in Netherlands?

In the same year, another 15 events of solar PV module related re accidents were reported in Netherlands . In 2012, a solar panel related re occurred in a warehouse in Goch, Germany, which caused a burning area of about 4000 m2 . The root cause of the solar panel related re accident is usually associated with a de cit in the PV system.

What happens if a PV array explodes?

As shown in Figure 7, explosion accidents during the combustion period in PV arrays have a large impact on the safety of operation and maintenance personnel. The explosion mainly come from the IGBTs and capacitors inside the inverter . The power of a capacitor explosion can penetrate a 2 mm thick steel plate.
