Battery storage was paired with 37 percent of new residential solar power systems in the United States in 2025, PV Magazine and pv magazine Global reported. The attachment rate increased from 25 percent in 2024, according to figures from the Lawrence Berkeley National Laboratory. [1][2]
PV Magazine noted that adoption of paired storage systems accelerated both in California and in other states across the country. Energy storage units are increasingly moving from an optional addition to a standard component of rooftop solar installation projects. [1]
Residential energy storage systems store electrical energy locally for later consumption and are usually built using lithium-ion rechargeable batteries managed by intelligent charging software. Companies are also developing smaller flow battery technology designed for residential deployment. [3]
Home storage devices represent smaller-scale versions of grid energy storage systems that support distributed generation. When combined with local electricity generation, residential batteries can eliminate power outages for off-grid homes. [3]
In short
- 37 percent of new U.S. residential solar systems included battery storage in 2025.
- The residential solar battery attachment rate rose from 25 percent in 2024.
- The data comes from the Lawrence Berkeley National Laboratory.
- Residential storage devices typically use lithium-ion rechargeable batteries.
