The demand for solar in the US is high, but number of skilled laborers willing to be on a roof is very low. Last year I called almost 40 installers, every one of them was booked out for at least 6 months, some for a year. So, they can demand a premium. Cost of hardware is also a lot higher. I was able to get panels for about $1/watt, iirc in AU it's closer to $0.45/watt (not installed, just the hardware).
