I imagine a series of rotating masses so if any single or several fail
(earthquake, etc.) the system wouldn't collapse.
 
As you say, there is little inertia in these solar systems unlike water or fuel
generated power.

If every solar inverter was networked and controlled in
voltage/current/phase angle, by some intelligent system controller,
one might not be so dependant on rotating mass.

As solar and wind get to be dominant, micromanagement of power sources
and loads will be necessary to ensure uptime.

(That's a big part of the green agenda: control everything.)
