Although I have no plans to put them on my house, I like the idea of rooftop solar shingles--especially if they can be integrated with the grid to pick up some of the daytime load.
Firefighters, however, have a different set of concerns. For example:
If there is a solar electric system involved, "pulling the meter" will only kill power coming in from the utility grid. Other circuits may remain live — household circuits if the system has battery backup or an auto-start gasoline generator, and PV circuits whenever the sun is shining. Multiple disconnects for various parts of the system are very common.
Some people in this county have roof-top solar panels. I am not aware of any in my little volunteer department's primary service area, but that is perhaps because I have not seen every single house.
