The fire brigades are well aware of how to deal with PV panels these days...

Yep - unless life is at risk, stay outside. The risk of live cables or
the panels falling though the roof is too great to risk the lives of
firemen, just to save property. In Germany, the insurance companies
won't even insure firemen who enter a burning building with solar panels
on the roof and they are experts at assessing risks.
