Fire In House With Solar Roof Panels Installed

When properly installed, photovoltaic cells do not cause fires. In cases where it has
been reported that there was a fire in house with solar roof panels installed, it was
not the panels, but improper electrical wiring leading to them, or some other malfunction,
and can cause a hazard if firefighters don't know that a system is installed. Let's take
a look at some other important factors to consider about this alternative electrical source.

In some locations, firefighters carry "hot sticks" which can detect electrical wiring, but
these tools only work for AC current. DC is what PV cells produce, and it is converted into
AC by the inline system inverter. If a home starts burning while the occupants are away,
there should be some method in place that will alert emergency personnel that a solar power
system is engaged.

When these units are mounted and connected, they should be inspected by qualified personnel.
There should be a rooftop shutoff valve to stop the flow of electricity in a box which is
clearly labeled on the outside of the cover. All indoor and outdoor portions of the conduit
needs to be labeled at each 10 feet, and all batteries enclosures should also be clearly labeled.

PV modules and the batteries they are charging up contain chemicals that are toxic if they are
released during a fire. Unless the emergency people know these units are there, they can be
engulfed by these fumes and be placed in much greater danger to loss of life or limb. These
units are quite heavy and can increase the possibility of roof collapsing when the flames causes
a compromise in the integrity of the structure.

These PV sections can become slippery, especially when they become wet, and can pose a risk
to the emergency people who are trying to put out the fire. Technicians, and other emergency
personnel are in danger of stepping on them without know they are there because the smoke from
the fire can obstruct their view.

When these devices are present, they also pose a risk by blocking possible entry points and
pathways that are typically used by emergency crews in fighting incendiary conditions. When
these modules are installed, care should be taken to leave sufficient room between the units
to allow safe passage, in the event of an emergency.

Controlling the amount of ventilation in a situation where a house is burning, is one of
the means by which the emergency crew can use to help bring the situation under control and
extinguish the flames. Due to their size and placement, these units can inhibit the efforts
at ventilation. A section of the roof should be exposed between the units in case there is a
need to ventilate the roof.

Each panel should be equipped with an arc-fault detection device that will shut down
individual modules in the event they should start arcing. All areas of operation should be
free of rodents and pests which compromise the wiring. And, a schematic should be registered
with the fire department for reference in the event of a fire in house with solar roof panels
installed.
