The separated leads look just like overheated printed circuit board
traces. You can see the discoloration on one where it rises up off the
substrate, which acts as a heatsink.

wow.  too bad they couldn't have pre-installed some aerial pyrotechnics
under the panels in some sort of weatherproof container, when the panels
went up they could've also enjoyed a nice pyrotechnics display, would've
made a great video for anti-PV people.

b.w.

I'm surprised the Fire Department didnít knock down the house to put the
fire out.

A UL listed panel means that its been tested  for Fire and Safety. If it
goes on fire it will not burn on its own (i.e. 94-V0)
and no one can be harmed if its installed properly.  Usually this is
needed for insurance purposes.  Now a days  it is really a high risk to
not use a UL panel.

Cheers
