10u152, I don't know where you live, but you seem to be quoting US solar prices. Tragically, US prices are 2x-3x that of Australian residential solar prices. Generally Australian prices are $10k-AUD for a 10kw array or roughly $6.6k USD for 10kw,[1] compared to the $20-25k USD in the US depending on location.

High US residential solar prices are a policy/political choice the US makes! [2]
