Except that by doing so, you'll drive the price differential down to
zero.  Not that that's a bad thing - off-peak power exists as an
incentive for people to invest in exactly this sort of thing, eg.
off-peak electric water heaters do this (sortof) on a tiny scale.
Just don't expect to make money from it forever, particularly if it
catches on (and since it's so great, that's to be expected)...  But at
least then power generation could be at a more efficient constant
rate, with the batteries levelling out the load.  In theory anyway.
