Over the past few years, there have been a number of media reports linking the PV system with fire. According to recent reports, the annual frequency of fire incidents for PV installations is 0.029 per megawatt. While this number may not seem alarming, however, with nearly 200 GW of PV systems now installed worldwide, an increase in incident reports is to be expected.
Arcs and residual current are considered the primary cause of serious fires in solar PV systems, which accounts for more than 60% of all incidents involving rooftop PV systems. Manufacturers, developers, and governments have been implementing measures for years to prevent arcing and system fires.
