Though fires from solar panels are extrtemely rare, they do happen.  Failure of the solar panel is not what usually causes the fire, it is caused my impropoer installation of the system.   That is why we use the Lumos Powermount 2.0 Rail system for our panels.  These high quality rails are designed with a wire chase to keep your wires neatly organized and off your roof.  Using a wire chase also reduces the need for zip-ties, which can add stress to the jacket of the wire.  Doing so helps reduce the risk of wiring issues greatly and also helps to keep debris from being caught on your roof under the panels.
