Physical category Physical faults internal to PV cells, such as cracked cells, broken solder joints and shorts between a cell string and the metal substrate, are reported to cause fires within various types of 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.
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.
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.
External influences that can cause solar panel fires include moisture and water ingress into parts of the PV system, such as the DC and AC connectors. Additionally, consideration should be given to things such as build-up of dirt, bird droppings, and foliage on PV panels. These can lead to shading, causing hot spots that can escalate to burning.
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.
