What is a PV hazard control system?

According to the Code and a UL standard, a PV hazard control system is a listed PV system that can be made essentially hazard-free to fire service personnel when placed into a hazard-free state by a PV rapid shutdown system initiator.

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.

Will shutting down PV systems protect first responders?

Shutting down PV systems in accordance with the National Electric Code requirements will protect consumers and first responders. SETO has funded work with Sandia National Laboratories and Underwriters Laboratory to quantify the potential risks that first responders face when fighting solar rooftop fires.

How does pvprotect prevent a fire?

This allows for fires to be detected early and located accurately. In the event of a fire, PVProtect automatically initiates the suppression to prevent uncontrolled spreading.

Do combustible cladding & curtain walls need a fire spread test?

For the vertical fire spread testing, the current local building codes require combustible claddings and curtain walls pass large-scale façade fire spread tests (NFPA 285, ISO 13785 etc.) exposing the BIPV to the window flame. ???

How can we manage the fire risk of existing PV installations?

In order to manage the fire risk of existing PV installation assets, and to accommodate the significant projected growth in the number of installations, there is an emerging need for harmonised, disciplined, and robust training and recognised competencies for system maintenance, underwritten by recognised authorities.
