Yes, grid-tie solar is all about the economics to the homeowner of renewable
energy production which is now CHEAPER than buying it from the coal plant.
But it is part of the grid which is what makes it so economical.  One still
has the issue of what to do with a power outage the 0.5% of the time, and
that can be met with many other cheaper alternatives... including a
transfer-switch so you can still use your solar panels and all their KW of
energy during an outage.

Good point.  That is another reason that Like briging all the solar panel DC
down to the basement and having the grid-inverter there, so if I ever needed
it, I couild use the raw solar DC output in other ways..

Ah, but it takes some aggression to move forward and to bring change to old
ways...
