Sunrun Accounts for Nearly 48% of U.S. Residential Battery Storage Installed in 2025
Sunrun installed nearly half of all residential battery storage capacity deployed in the U.S. in 2025. According to the Solar Energy Industries Association's inaugural U.S. Energy Storage Market Outlook report, the residential energy storage sector added 3.1 gigawatt-hours of new capacity in 2025. Based on Sunrun's own reported results of 1.5 gigawatt-hours installed during the same period, the company estimates this represents approximately 48% of the sector's total. Sunrun has now installed more than 237,000 storage and solar systems, representing approximately 4.0 gigawatt-hours of Networked Storage Capacity. That amount is equivalent to 44% of the 9 gigawatt-hours of residential energy storage installed across the U.S. since the industry's inception, based on SEIA's cumulative data.
