California PV Energy Storage Prices

How much does solar PV cost in California?

We assume that the installation cost of residential solar PV systems in California is $3.75/W in 2020, given that the median installed price of such systems before incentives in California was $3.81/W in 2019, and we assume a same price drop (−1.7%) for 2019-2020 with that in 2018-2019 ( Barbose et al., 2020 ).

How much does a storage system cost in California?

The average cost of a storage system in California in 2023 is $1096 per kWh, resulting in an average installation cost of $14,252 for a 13 kWh system. As of October 2023, the cost of a storage system in California ranges from $12,114 to $16,390.

Are solar PV & energy storage costs rising in Q1 2022?

U.S. Solar Photovoltaic System and Energy Storage Cost Benchmarks, With Minimum Sustainable Price Analysis: Q1 2022 details installed costs for PV and storage systems as of the first quarter (Q1) of 2022. Prices soared throughout the U.S. economy between Q1 2021 and Q1 2022, for the PV and energy storage markets in particular.

What is PV and storage cost modeling?

This year, we introduce a new PV and storage cost modeling approach. The PV System Cost Model (PVSCM) was developed by SETO and NREL to make the cost benchmarks simpler and more transparent, while expanding to cover components not previously benchmarked.

Will California's New PV rules affect PV-plus-storage systems?

In the longer term, analysts expect the new rules to constrain PV-only deployment in California and ultimately spur the deployment of PV-plus-storage systems, which have higher upfront costs (Wood Mackenzie and SEIA 2022b). Our interviews also indicated market and policy trends affecting system costs between Q1 2022 and Q1 2023.

Do solar-plus-storage systems save money in California?

Assuming current lifecycle costs and rate structures, solar-plus-storage systems do not offer savings for most households in California, unless subsidies or tax breaks are implemented. The savings in utility bills through battery arbitrage often cannot compensate for the high upfront cost.
