6 FAQs about [Causes of photovoltaic inverter explosion and fire]
Are solar PV systems causing fires?
Our engineers and inspectors have inspected over 10,000 grid-connected solar PV systems in the past ten years. During this time, we have concluded that there are three main causes of fires: DC isolators, especially the DC isolators located at the roof (rooftop isolators), are a known common cause of fires in PV systems.
What causes a roof-mounted PV system to fire?
Incorrectly installed or defective system components have been the cause for several PV fires as well. In addition, numerous fires have started in roof-mounted PV installations due to DC arcs caused by inadequate ground fault protection. Several fire incidents involving rooftop PV systems are discussed below.
Are PV panels causing fires?
Half of the cases were caused by PV panel systems, and the other half were started from an external source. It is reported that approximately a third of the fires caused by the PV panel systems were due to PV component defects. The rest of the cases were equally caused by planning errors and installation errors (Sepanski et al., 2018).
Did the PV system cause a fire?
In total some 400 incident reports were found. Some 180 out of these reports found that the PV system caused the fire. Please note: For most incidents only a fraction of information was available. Thus, each topic of analysis may be based on a different number of events.
What causes a combustible material to ignite in a PV system?
These faults and other system failures, including cable insulation breakdowns, rupture of a module, and faulty connections, can result in hot spots that can ignite combustible material in their vicinity. Incorrectly installed or defective system components have been the cause for several PV fires as well.
Can a PV system fire cause property damage?
The following recommendations are intended to reduce the potential for property damage and business interruption caused by PV system fires. Most items refer to rigid PV modules (BAPV) since there is limited experience to date with BIPV and flexible PV modules. If possible, ground-mounted PV systems are preferred over roof-mounted installations.
