The issue of the externally accessible utility disconnect switch is one
of the relative magnitude of the risk - we all live with other more
significant risks every day that we feel that are acceptable...
I think in many cases the utility goes overboard on requiring the
disconnect when it is clearly not going to be used due to the location
and access issues involved. I have seen several sites where the desired
location of the disconnect and the type required by the utility made the
installation uneconomical. Most of the lineman I have talked with say
they will pull the meter if they had a real concern about the system.
The reason why PV systems will not island in the real world is due to
physics - which is pretty reliable stuff in my experience. The
comparison to nuclear power is not fair - Nuclear power, in contrast, is
bound to fail because of the physics involved.
