In some states, like NY (I believe), even if you disconnect
from the grid, the property owner is charged a monthly
having-the-grid-available fee.
If PV owners are charged a grid-maintenance fee, then
so should all others connected to the grid, especially
if their usage is small, right?
Most low-net users are already charged a monthly
minimum, usually around $5 to $10, usually per
meter, I would guess.
The only way to fight it, I guess, is to move most of
your usage to peak time, so that there is very little
over-generation during the day. For example, charge
cars or other batteries during high generation, rather
than at night, when the grid is under-utilized,
and power is usually less expensive.
However, since the Utility generally collects enough
to make a fixed percentage profit on their expenses,
they generally would love having more expenses, I think.
