How do you protect a solar system from a fire?

On the surface, the process seems simple, however, there are many steps required to ensure safety. Firefighters arrive at the scene of a fire, and then identify the solar system on the structure, shut it down, watch for hazards as they extinguish the flames, and make sure the scene is safe when they leave.

Are solar panels safe for firefighters?

The DC power generated by solar panels cannot be completely de-energized while exposed to light, making standard electrical safety protocols insufficient. Firefighters must maintain safe distances from solar arrays and use appropriate personal protective equipment (PPE) rated for electrical hazards.

How do firefighters protect solar panels from electrical hazards?

Firefighters should establish clear paths to ventilation points that avoid crossing over or cutting through solar panels whenever possible. A minimum clearance of 4 feet should be maintained between ventilation holes and solar array edges to ensure structural integrity and prevent electrical hazards.

Are PV systems a fire hazard?

PV systems can pose several hazards during firefighting efforts, including the risk of electrical shock from live system components, especially due to electrical current flowing through water. Firefighters are also at risk from mechanical and thermal stress on the glass of PV modules.

Can firefighters respond to solar energy fires?

As solar energy systems become more common, firefighters need to be equipped with the knowledge to safely respond to fires involving PV-equipped structures. SETO awardee, IREC, developed free, self-paced, interactive online training and live workshops designed specifically for firefighters.

Should firefighters work near PV systems?

Firefighters should prioritize safety when working near PV systems. The National Electric Code outlines the required minimum distances between live electrical parts and firefighting equipment to prevent electric shock.
