NREL has released an inaugural report highlighting utility scale energy storage costs with various methods of tying it to solar power: co-located or not, and DC- vs AC-coupled.
In 2024, solar photovoltaics (PV) were, on average, 41% cheaper than the lowest-cost fossil fuel alternatives, while onshore wind projects were 53% cheaper. Onshore
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 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).
When PV and battery storage are co-located, they can be connected by either a DC-coupled or an AC-coupled configuration. DC, or direct current, is what batteries use to store energy and how PV panels generate electricity. AC, or alternating current, is what the grid and appliances use.
When choosing between DC and AC, the technical factors that affect the system’s performance must be considered, as well as costs. The cost of the co-located, DC-coupled system is 8% lower than the cost of the system with PV and storage sited separately, and the cost of the co-located, AC-coupled system is 7% lower.
We chose a 100-MWdc PV system because that was the approximate average size of U.S. utility-scale systems reported in EIA (2022). The per-unit cost results are meant to be generally applicable to systems with PV sizes between about 50 and 200 MWdc.
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).
