Hybrid PV/Battery/Generator [RE-wrenches]

Graham:

Interesting idea but...
Check out some of Tom Hund's (Sandia) work on this subject.
As I recall, his conclusion was that the round trip cost for the energy
was about $0.35 per kWh.
Not quite enough to make it worthwhile even with time of day net
metering.
Perhaps the economics will be a bit better with the advanced batteries
in EV's.

Check out this website http://www.acpropulsion.com
They are developing electric cars that charge up at night with grid 
power, then sell the power back to the grid during peak demand.  From 
what I have been told, the founder Allan Cocconi, is a genious when it 
comes to inverter technology.  I know this dosn't help with solar 
projects in the works now, but there is some intersting stuff on the 
site.
