The aluminum rails and module clamps are imported from China and subject to 25% tariff. Each module is paired with a microinverter rated at 330 W ac, giving the PV system a rated AC power output of 6.6 kW ac, which corresponds to an inverter loading ratio of 1.22.
The representative residential PV system (RPV) for 2024 has a rating of 8 kW dc (the sum of the system's module ratings). Each module has an area (with frame) of 1.9 m 2 and a rated power of 400 watts, corresponding to an efficiency of 21.1%.
(EIA, 2023a) reported that 140 PV installations (greater than 5 MW AC in capacity) totaling 10.3 GW AC were placed in service in 2022 in the United States. This represents an average of approximately 73 MW AC; 86% of the installed capacity in 2022 came from systems greater than 50 MW AC, and 52% came from systems greater than 100 MW AC.
