Full disclosure-former power company employee.
I haven't given it a look. Just over a 1 year old house so its well insulated, and we're at 8.something cents per kwh. Only way I'd look into it would be for 1-prices to jump and 2-they go to time of day charges for power. Solar could then be effective shaving off peak costs when the AC is ratcheting up. Even then, its not an assurred deal since most peak loading is now being carried by nat gas turbines, and gas is still cheap.
Factor in a carbon tax, or more gas line restrictions and that could change though.
Consumer Reports did an evaluation of 3 houses in the southeast a few years back. Looked at cost financed over time vs savings. IIRC, only one case came out ahead of the 3.
