In 2022, the home energy storage market exploded. According to the data released by EVTank, the newly installed number of global home energy storage reached 15.6GWh in 2022, with a year-on-year growth of 136.4%.

EVTank estimates that 52.6GWh of energy storage will be installed globally by 2025, and 172.7GWh by 2030. By then, the cumulative installed global energy storage capacity will reach 748.9GWh.

Home energy storage belongs to lightweight energy storage, which is oriented to the user side, similar to consumer goods. Home energy storage system is generally composed of energy storage system and photovoltaic modules. At present, the home energy storage system market is mainly composed of energy storage battery and inverter split machine, but the development trend of high-end market is all-in-one machine.

Typical home energy storage system specifications are a 5kw PV system +10kWh storage battery, or a 10kw PV system +20kWh storage battery. Taking 5kw+10kWh home storage system as an example, energy storage battery accounts for the largest proportion of equipment cost, accounting for 48%, inverter, photovoltaic module accounts for 24% and 22%, respectively.

In terms of industry chain, the home storage market also has upper, middle and lower reaches. The upstream of Home storage is mainly a variety of component manufacturers, including battery manufacturers (BYD, LG, Peineng Technology, Panasonic, Yiwei Lithium Energy, Haichenenergy Storage, etc.), inverter manufacturers (Tesla, Jinlang Technology, Goodway, etc.), photovoltaic module manufacturers (segen, sunrun, etc.), and other component manufacturers. The midstream of Home storage is mainly a variety of integrators, brands and installers, including Tesla, BYD, Sunpower, Segen, Sonnen, Sunrun, SunPower, etc. Downstream is a variety of home storage users.

EVTank data shows that the top 4 global home storage markets in 2022 from high to low are the European market, the United States market, Japan market and Australia market.

The European market is the largest household energy storage market in the world. Due to its strong dependence on imported energy (natural gas), energy shortage caused by Russia-Ukraine conflict, combined with high electricity price and government policy support, the newly installed household energy storage in Europe will be 5.68GWh in 2022, accounting for 36.4% of the global market, and its cumulative installed capacity will exceed 10GWh. Germany, Italy, Austria and the UK will be the TOP4 countries in the European home storage market in 2022.

EVTank has conducted a detailed study and analysis of the market shares of major home energy storage system providers and major home energy storage battery providers. In terms of home energy storage system providers, Tesla, Pinone Technology and Huawei occupy the top three market shares of global system providers. Tesla has benefited more from the U.S. home energy storage market, while companies like Pinergy Technology and LGES have benefited from Europe.
