Solaredge SE 6000H Inverter
$16,600
-$1,280 ODOE
-$1,920 Energy Trust
-$3,484 Federal tax credit

$9,916 final cost
$1.55/watt

2 weeks later my parents are getting:

Nameplate output: 8.88 kW
Annual production: 11,000 kWh
Hyundai 370W panels x24
Power Optimizer x24
Solaredge SE7600H Inverter
$23,000
-$5,000 ODOE
-$9,000 Energy Trust
-$2,340 Federal tax credit

$6,600 final cost
$0.75/watt

Other than the obvious difference for the size of the systems, is your parent's additional cost savings due to their age?
