As you say, there is little inertia in these solar systems unlike water or fuel generated power.

 The sun is *still* shining.  Why can't *it* supply the power
to all of the distributed inverters around the country at the
appropriate phase angle?  You only need storage if your
actual source of power disappears, relative to the load.
 I.e., turn excess generation capacity to "braking mass"

The sun disappears every night, and less sunlight gets through when the sky clouds over. Extra solar panel area and grid scale storage makes this easier to deal with.
