Answer 1

The correct order of components for a residential rooftop PV system layout is: Solar PV Modules, DC Disconnect Switch, Grid-Tie Inverter, Breaker Box, AC Disconnect Switch, REC Generation Meter, Utility Distribution Meter, and Utility.

Step-by-step explanation:

The correct order of components for a residential rooftop PV system layout is as follows:

1. H. Solar PV Modules: These are the panels that convert sunlight into electricity.
2. E. DC Disconnect Switch: This switch allows the system to be disconnected from the DC power source.
3. C. Grid-Tie Inverter: The inverter converts the DC electricity from the solar panels into AC electricity.
4. F. Breaker Box: This box distributes the AC electricity to the different circuits in the house.
5. B. AC Disconnect Switch: This switch allows the system to be disconnected from the AC power source.
6. G. REC Generation Meter: This meter measures the amount of electricity generated by the system.
7. D. Utility Distribution Meter: This meter measures the amount of electricity used by the house and any excess electricity that is exported to the utility grid.
8. A. Utility: The utility grid is the main source of electricity for the house when the solar panels are not producing enough.
