Battery storage attachment rates continue inching upwards. In 2023, 12% of all new residential PV installations and 8% of all non-residential installations included battery storage. As usual, Hawaii was in a category of its own, with residential and non-residential storage attachment rates of 95%.
The US solar industry installed 7.5 gigawatts direct current (GW dc) of capacity in Q2 2025, a 24% decline from Q2 2024 and a 28% decrease since Q1 2025. Solar accounted for 56% of all new electricity-generating capacity added to the US grid in the first half of 2025, with a total of 18 GW.
There is economic potential for up to 490 gigawatts per hour of behind-the-meter battery storage in the United States by 2050 in residential, commercial, and industrial sectors, or 300 times today's installed capacity. But only a small fraction could be adopted by customers, according to the latest.
