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%.
We assume the solar technology is photovoltaic (PV) with single-axis tracking. A solar PV-battery (PV-battery) hybrid system is a single-axis PV system coupled with a four-hour battery storage system. Costs are expressed in terms of net AC (alternating current) power available to the grid for the installed capacity.
The DC conductors are connected to 220 three-phase string inverters, each rated at 10 kW ac, giving the PV system a rated AC power output of 2.2 MW ac, which corresponds to an inverter loading ratio of 1.37. The inverters are made in China in a plant that produces 100,000 of them each year and are subject to 25% import tariff.
