Based on our bottom-up modeling, the Q1 2021 PV and energy storage cost benchmarks are: $2. 65 per watt DC (WDC) (or $3. 05/WAC) for residential PV systems, 1.
Are solar photovoltaic system and energy storage cost benchmarks a unique fingerprint?
Dive into the research topics of 'U.S. Solar Photovoltaic System and Energy Storage Cost Benchmarks: Q1 2021'. Together they form a unique fingerprint. Ramasamy, V., Feldman, D., Desai, J., & Margolis, R. (2021).
The modeled $/kWh costs for 600-kW Li-ion energy storage systems vary from $469/kWh (4-hour duration) to $2,167/kWh (0.5-hour duration). The battery cost accounts for 41% of total system cost in the 4-hour system, but only 11% in the 0.5-hour system.

What are the cost parameters for a commercial Li-ion energy storage system?
Commercial Li-ion Energy Storage System: Modeled Cost Parameters in Intrinsic Units Min. state of charge (SOC) and max. SOC a Note that, for all values given in per square meter (m2) terms, the denominator refers to square meters of battery pack footprint. The representative system has 80 kWh/m2.
On the other hand, PV and storage market prices are influenced by short-term policy and market drivers that can obscure the underlying technological development that shapes prices over the longer term.
