I don't live in the 'outback' and I didn't install my panels and they 
have all approvals. Our 1.5 kW system (with a 2kW inverter for 
expansion) cost $2000AU complete, installed. Honestly. They were $2300 
with a govt subsidy, then when it was removed guess what - the price 
dropped anyway.

But looking around, it seems one area Americans may be being got at.
If they really do cost $7-9 per W there it would be truly prohibitive.
If that's the case I can see your point.
