Was that fire isolated to the array, or did it spread to the building too? I have seen so many j-boxes were a connection has come loose, then arcs. This is particularly true of systems with wirenuts. If enough sunlight is present, and the wires begin to arc, then the arc could travel out of the box, and start a fire.
I have serviced many modules that have failed, and found melted j-boxes and cables melted off the backs of panels. Recently, I pulled a module off of a roof, and nearly half the module's backing was blackened and charred. Many of those failures could have lead to a fire. We are all at risk of this happening.

Most likely reverse polarity of a string or whole combiner box feeder at the inverter. Details to come. Bill.
