Even though PV systems can produce high voltages, the AC line voltages that come into all structures can be much more dangerous. On a recent fire, I noticed that the utility service drop was within easy contact and the insulation on the wires was missing in some spots. Since this is on the utility side of the meter, the current would be unregulated up to the limits of the wire, which could be close to 1,000 amps—a serious electrocution hazard.
