Tadink, thanks for the info. I am not really worried about tax credits and would prefer my money work for me, rather than paying a huge chunk up front.
3.56 kW system. Call it 3.6kW.

$3600 for 16 x 225 Watt panels.
$3200 for 16 x micro inverters

They are getting $10K for the racks, wiring and install? I think you might be able to find it cheaper than that.

Flip it the other way. How much are you paying for electricity right now? @$0.20/kWh and the 30% tax credit, the unit produces $1560/yr. And I bet your average $/kWh is above $0.20.

Show me an investment where $16K (really $11.2K) is going to pay out $1560 per year.
