Underwriters Laboratory (UL)3741 addresses safety processes and principles for evaluating, and recognizing compliance for, rapid-shutdown PV arrays that protect firefighters from shock hazards on rooftops with solar panels.
To achieve UL 3741 certification, products must pass a series of tests designed to simulate situations firefighters may encounter on a solar rooftop. The testing analyzes what happens when first responders fall on damaged solar panels while wearing typical protective gear.
