From my recollection of a documentary I watched a few years ago: You can cut power to the burning building if the fire hasn't already destroyed the circuit(s) itself, solar panels though are not bound to the utilities thus can't be shut off remotely and could give electric shocks to the firefighters/left-over occupants. IIRC there were some nasty accidents that happened like this.
