They are priced according to five different power ratings to provide a relevant system comparison and a more precise estimate. The power rating of an energy storage system impacts system pricing, where larger systems are typically lower in cost (on a $/kWh basis) than smaller ones due to volume purchasing, etc.
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:
These benchmarks help measure progress toward goals for reducing solar electricity costs and guide SETO research and development programs. Read more to find out how these cost benchmarks are modeled and download the data and cost modeling program below.
The AC-coupled system assumes a DC/AC ratio of 1.4, resulting in a DC size of 210 MW. AC-coupled systems are typically built at a higher DC/AC ratio than standalone PV to maximize the amount of available energy to charge the battery energy storage system (BESS) without sacrificing PV output while the BESS is charging or idle.
The benchmarks in this report are bottom-up cost estimates of all major inputs to PV and energy storage system installations. Bottom-up costs are based on national averages and do not
