Yeah, that number is way off, by a factor of 2-3!  It's really more like
$3-5/W nowadays...  And that's *BEFORE* any federal or state subsidies.
I've priced out a 7.2kW array with micro-inverters at around $25k.
Alas, my limiting issue is viable roof real estate.

You really should recheck your numbers.  Solar has come down in price
SIGNIFICANTLY in the past 2-3 years!
