“I mean, the battery storage attachment rates increased significantly over the course of the last couple of years. It used to be two or three percent. Now it's like 25%.”

The claim, plainly

The battery storage attachment rate for residential solar systems in the US increased from 2-3% to approximately 25% over a few years leading up to 2022.

Assessment

Industry tracking data from Wood Mackenzie, SEIA, and Lawrence Berkeley National Laboratory (LBNL) demonstrate that the nationwide residential solar-plus-storage attachment rate in the United States was approximately 8% to 11% between 2020 and 2022, not 25%. LBNL's Tracking the Sun report recorded the national residential attachment rate at just under 10% in 2022 (rising to 12.3% in 2023), while Wood Mackenzie reported national rates of 6% in Q1 2020, under 11% in 2021, and 11.1% in Q1 2023. The nationwide attachment rate did not reach 25% until Q1 2024. While specific individual installers (such as SunPower at 24% in Q1 2022) and select state markets reached higher levels, the overall U.S. residential market was materially below the claimed 25% at the time the statement was made in early 2022.

According to Wood Mackenzie (The state of US distributed solar-plus-storage, June 2024), the national residential storage attachment rate was 6% in Q1 2020, under 11% in 2021, and did not reach 25% until Q1 2024.
Lawrence Berkeley National Laboratory's Tracking the Sun (2024 Edition) data recorded the U.S. nationwide residential solar battery attachment rate at just under 10% in 2022 and 12.3% in 2023.
Wood Mackenzie's August 2023 analysis found that only 11.1% of residential solar installations in the U.S. in Q1 2023 were paired with storage.
