A big advantage to solar as I see it would be the ability to have electricity even when the utility is down - all your neighbors would be envious!!

The grid-tie systems that I've been reading about (like these tiny units),
Enphase Micro-Inverters
Shut right down if the grid power starts acting up. If the grid goes dead,
so does your system..
For home backup power during a blackout, you would need a more complex system.
One that includes a battery system and a mains disconnect.
Or a disconnect box similar to those used with gas generator backup.
