I need a sanity check with respect to costs of a DIY system. Assuming I am performing all the work myself. Costing, and sourcing panels, inverters, wiring, etc...
From project solar, they advertise $1.26 per Watt for a DIY install. It seems to be a decent price, but when I go out and quote 18kW of panels @$0.30/Watt, $2600 for grid tie inverters, $1k-$2k hardware (wire, breaker box, mounting hardware), I am calculating about $0.43/Watt after federal tax incentives. So what gives? Surely I'm missing something. I also cant seem to find this math being done by others. So I have a low confidence in it. Please feel free to beat me up
Heres my hardware lineup
45 x Hyperion 400w panels (HY-DH108P8B) - $5577
2x Growatt 10kW Grid-Tie Inverter - $ 2600
Hardware - $2000
Total = $ 10,177 ($7124 after incentive) or (0.395/Watt)
