How hard would it be to build a battery system that normally supplies
100% of the domestic power but, when depleted, switches over to supply
domestic power from the grid ? Also, I think it would be safe
assumption, or at least a reasonable simplification, to assume that
the
battery is always sufficient for the load, except when depleted. The
battery would always be charging from a solar array, never from the
grid.
It seems to me, a system like this would completely circumvent any
negative conditions imposed by power companies. Of course, once the
solar panels fill the battery, excess production is lost.
