Global residential energy storage capacity installations are projected to reach 46.1 GWh in 2026, according to InfoLink Consulting's latest Global Residential Energy Storage Market and Shipment Database.

Europe remains the key contributor to the market, with capacity additions set to reach 15.4 GWh, InfoLink said. Germany, Italy and Austria continue to perform strongly, while the Netherlands and the UK are seeing significant growth driven by policy support. Eastern European markets led by Ukraine are also emerging rapidly.

Capacity additions in Oceania and Asia are gradually approaching Europe's levels, with Australia's Cheaper Home Batteries Program expected to make the country the world's largest single-country residential storage market this year.

Asia's growth is led by Pakistan, the Philippines, Vietnam and Japan, where frequent outages and high residential electricity prices are driving demand. The Americas, Middle East and Africa remain smaller markets, with demand centered on the U.S., South Africa, Nigeria, Kenya, Iraq and Israel for backup and off-grid power.

Fox ESS, Sigenergy and Deye ranked as the top three global suppliers by first-half shipment volumes, with market shares of 11.5%, 11.3% and 11% respectively. No supplier holds an overwhelming advantage, with the market remaining highly fragmented.

The report identified five key trends in the 2026 residential energy storge market: rising adoption of all-in-one PV-plus-storage systems; suppliers expanding into commercial and industrial and balcony micro-storage; integrated whole-home solutions combining PV, storage, EV charging and heat pumps; growing attention to AI capabilities and virtual power plant connectivity; and increasingly differentiated product needs across regions.
