The average residential consumer uses 29.6 kWh per day so 2.24 days of storage is 66.3 kWh- pretty close to 50 kWh! Also worth noting that the average daily power consumption for electric cars would only be ~8.5 kWh per person.

Yeah... and being actively fought against, annoyingly. Variable rates aren't even available to most people.
You're talking about variable rates? Hawaii is a good example of what the future might look like, unfortunately. The power companies there are fighting very hard against variable rates because it would make solar way, way more feasible. It's kind of an extreme example because solar power could virtually eliminate Hawaiian power companies at a very substantial cost savings and a very short timescale, but the same principal elements are present everywhere in the mainland US too.
Australia has a lot of variable rates though, so that's nice for them.
Yes, I was talking about variable rates. Australia is a slam-dunk for solar because of the great weather/insolation plus the high cost of electricity.
Hawaii's economics are midway between Australia and the mainland US, they won't be able to resist for very long. At the least, the utility companies there can't resist buying solar for themselves! http://fortune.com/tesla-solarcity-battery-solar-farm/
