The Recognition of Fires Originating from Photovoltaic (PV) Solar Systems

There has been an observable increase in the fitting of photovoltaic (PV) solar panels on the roofs

properties has been attributed to PV systems. This thesis examines the ability of fire examiners to

investigating the effect of internal heating in direct current (DC) isolators to the point at which they

This clarified that national fire data cannot identify the specifics of electrical fires. Validity of these

of fire, (especially when associated with PV systems), of some fire staff responsible for collecting

recognise fires originating from PV systems. Evidence for fires occurring in PV systems in Kent

evidence. This provided an indication that a potential common point of failure, which may lead to

probably within the DC isolator switch itself. Experimentation revealed that internal heating of a

structural integrity and therefore allowing an arc to be established. Observable post fire indicators

from pyrolysis of isolator insulating material.

Finally, areas for further experimental research and training of fire staff are suggested as well as

the modification of recording mechanisms and building regulations.
