According to Straits Research, the global residential battery market valued at $21.8 billion in 2025, is projected to grow from $25.77 billion in 2026 to $98.34 billion by 2034 at a CAGR of 18.22% during the forecast period 2026–2034.
Residential batteries store electric energy for future use. Lithium-ion or lead-acid batteries are the most common types, as they can handle charging and discharging cycles well. These batteries have proven incredibly beneficial in outlying areas without a dependable grid connection. The market for these batteries is expected to expand as more homes install rooftop solar power. Users can store energy for use during blackouts thanks to these rooftop solar installations.
The cost of lithium-ion batteries has fallen significantly over the past ten years. A lithium-ion battery was estimated to cost around USD 123 per kWh in 2021. Throughout the previous few years, the price has been steadily declining; compared to 2010, the price dropped by more than 85% in 2021. The two key reasons for the drastic cost decline are the steady improvement of battery performance and the increase in production volume, particularly in China. In addition, battery manufacturers across Asia-Pacific, particularly in China, have lower prices than the average prices. Low labor costs are a primary reason for the lower prices in China.
Furthermore, the decline in the average price of lithium-ion batteries is expected to continue and reach approximately USD 82/kWh by 2025, making the Li-ion battery market much more cost-competitive than other battery technologies across the residential sector. The trend is expected to increase the use of lithium-ion batteries in markets, such as residential energy storage systems (RESS), paired with renewables, like solar photovoltaic, during the forecast period.
As renewable energy technologies like solar gain prominence, there will likely be more possibilities for battery energy storage. Lithium-ion batteries are now preferred because of their high energy density, high output voltage, and low self-discharge rate. New lithium-sulfur batteries, however, have a 2600 Wh/kg higher energy density and a 2-volt open circuit voltage than conventional lithium-ion batteries. The lithium-sulfur battery is composed of a lithium-negative pole and a sulfur-positive pole.
Lithium's negative pole disintegrates into the electrolyte during discharge, and lithium ions go to the positive pole of sulfur to create polysulfide ions (Li2Sx). The lithium-ion moves to its negative pole as the polysulfide ion breaks down while being charged. Polysulfide ions gradually lose some of their solubility. As the reaction nears completion, Li2S2 and Li2S separate from the solution and create a solid residue that lowers the mobility of the positive pole sulfur and the battery's capacity. In September 2021, a business named Lyten presented the next-generation lithium-sulfur battery. These developments should boost market growth.
Based on region, the global residential battery market is bifurcated into North America, Europe, Asia-Pacific, Latin America, and the Middle East and Africa.
Asia-Pacific is the most significant global residential battery market shareholder and is expected to exhibit a CAGR of 18.91% over the forecast period. Abundant natural and human resources support several developing economies in Asia-Pacific. India and China are the two regions that provide the most to the region's revenue, which makes up the majority of it. These nations are expected to demonstrate tremendous growth potential over the forecast period. The Chinese market is anticipated to expand throughout the forecast period due to regulatory and policy support from the government. With subsidies and installation goals, the Chinese government has already demonstrated its capacity to catalyze a rapid increase in domestic demand for solar-related technology. In addition, residential rooftop solar capacity in China grew by 7.41 GW in the first nine months of 2020 and by another 64.61% in the following year. In September 2021, the nation's residential rooftop solar capacity increased by 2.14 GW.
Europe is estimated to exhibit a CAGR of 17.12% over the forecast period. Germany is among the largest markets for residential energy storage in Europe and across the globe. Due to the nation's ambitious energy transition initiatives and goal of lowering greenhouse gas emissions by at least 80% (relative to 1990 levels) up until 2050, the market for energy storage has seen a considerable uptick recently. The country also plans to phase out nuclear power plants by 2023, which is expected to increase renewable energy development to compensate for the reduced power-producing capacity. According to Germany Energy Storage Association, at the end of 2020, residential energy storage systems capacity was approximately 831 MW. Approximately 70% of residential solar PV systems are installed with battery storage systems, with an average capacity of 8.5kWh, slightly more than the average 8kWh in 2019. In 2020, according to the German Solar Industry Association (BSW-Solar), approximately 88,000 new residential storage systems were installed in Germany. Overall, battery storage systems increased to around 272,000 by December 2020. Furthermore, in 2019 and 2018, the country installed 60,000 and 40,000 residential batteries, respectively, and the demand for residential batteries increased by approximately 47% in 2020, thereby driving regional market growth.
