You are sketching the layout of a residential rooftop PV system to share with your installation team. Place these system components in the correct order by entering the corresponding letters with no punctuation or spaces. Use all components listed below. Note: Two of these components are not specifically labeled in the associated video lesson, but should be readily identifiable. You can begin and end on either end of the system- both answers will be scored correct.
A. Utility
B. AC Disconnect Switch
C. Grid-Tie Inverter
D. Utility Distribution Meter
E. DC Disconnect Switch
F. Breaker Box
G. REC Generation Meter
H. Solar PV Modules
