The current MSP benchmarks for PV systems in 2022 real USD are $28.78/kWdc/yr (residential), $39.83/kWdc/yr (community solar), and $16.12/kWdc/yr (utility-scale, single-axis tracking). For MMP, the current benchmarks are $30.36/kWdc/yr (residential), $40.51/kWdc/yr (community solar), and $16.58/kWdc/yr (utility-scale, single-axis tracking).
Market prices can include items such as smaller-market-share PV systems (e.g., those with premium efficiency panels), atypical system configurations due to site irregularities (e.g., additional land grading) or customer preferences (e.g., pest traps), and specific project requirements (e.g., unionized labor).
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.
We model a baseline 8-kWdc rooftop PV system using 20.8%-efficient, 1.97-m2 monofacial monocrystalline silicon modules from a Tier 1 U.S. supplier, microinverters with an inverter loading ratio (ILR) of 1.21 imported from China with the Section 301 tariff, and a 5-kW/12.5-kWh alternating-current (ac) coupled lithium-ion storage system.
Key implications ‒ The cost of generating and storing renewable power has fallen almost without interruption for the past several decades. Although recent turmoil in supply and logistics chains has
