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%.
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.
The total cost over the service life of the system is amortized to give a levelized cost per year. In the PV System Cost Model (PVSCM), the owner's overnight capital expense (cash cost) for an installed PV system is divided into eight categories, which are the same for the utility-scale, commercial, and residential PV market segments:

The performance ratio featured a standard deviation of 11.7%, indicating significant variability in the performance of individual systems, with only one or two systems achieving model-estimated energy delivery. Some level of underperformance is expected, and 100% availability would be prohibitively expensive to pursue.
Previously, FEMP developed an approach to evaluate the performance of solar photovoltaic (PV) systems at federal sites. The methodology was used to evaluate the performance of 75 federal PV systems and compile statistics regarding KPIs of PV system performance.
It is interesting to observe in Fig. 11 that the case of SSR of 99.44 % (i.e., nearly 100 % of energy consumption is provided by PV and ESS) is dominant in most of impact categories (9 over 12).
The KPIs reported are Availability (% up-time) and Performance Ratio (PR). If the PV system output was zero or less than 5% of the model estimate, then the time interval was counted as “unavailable.” For hours when the PV system was “available,” the measured energy delivery was divided by a reference yield to calculate PR.
