Dan:
Your observation is absolutely the truth. I was required to install a
disconnect when I put my system in. Every time I see a line crew in the
neighborhood I would stop them and ask if they new there was a grid-tie
system nearby. The answer was always that their plans did not indicate
grid-tie systems.

PS: When we remodeled I replaced my service and removed the disconnect.
