Firefighters putting out a fire may need to cut into walls or the roof in order to put out a fire. Since there are potentially energized wires in the walls and in the roof, a hazard exists for firefighters. Normally you can turn off the power to a house by removing the electrical meter (at least here in the US anyway), which emergency personnel may do if they are concerned about cutting into energized wires.
I figured that, whether power came in from a solar panel or the grid, the danger of energized wires would exist regardless. Did not realize they would be able to disconnect the burning house from the grid. Though I wonder what they'd do if the meter is inside the house.
