6 FAQs about [Photovoltaic inverter alarm hazards]

Are PV systems a fire hazard?

There is currently no national UK guidance specific to fighting fires involving PV systems. In most respects, fires involving photovoltaics are little different from any fire involving live electrics, however, PV systems do present some new risks to fire-fighters:

Are PV panels a hazard?

This hazard grows if the support beams are weakened during a fire. The modules could also fall during the fire, endangering both inhabitants and first responders. Be careful during the designing process and consult with the structural engineer if necessary. Always inform firefighters of the presence of a PV system on the roof. 4.

Are photovoltaic power systems causing fires?

Over the past few years, there have been a number of media reports linking photovoltaic power systems (PV) with fire. With the prevalence of PV systems now in the UK, an increase in incident reports is to be expected.

What are the risks associated with a PV system?

There may be restricted access to isolation switches. General electric shock risk from PV systems and the production of potentially very high voltage DC electricity. Parts of the system are always live while the PV modules are exposed to daylight. Risk of electric shock if cables are cut or become damaged by fire.

What happens if a solar PV system is damaged?

If they or you are however not complying with the correct design, installation and maintenance guidelines, insurance cover may be void in the event of a claim on fire damage caused by your solar PV system. Reportedly fire damage from a PV system at a farmhouse in Devon resulted in uninsured losses of over £800,000. What do I need to do?

Are solar electric/photovoltaic systems a threat to fire safety?

Research commissioned by the DCLG and carried out by BRE on fire safety and solar electric/photovoltaic systems, identifies the major obstacle facing firefighters: “In contrast to the power used by conventional mains electrical equipment, the power that PV systems generate is DC (direct current) and parts of the system cannot be switched off.
