Top 10 powerwall home energy storage manufacturers in the world

As for related manufacturers, the top 10 power wall manufacturers for home energy storage are Tesla、Pylon Tech、Sonnen、LG Energy、Alpha ESS、BYD、Enphase Energy、E3/DV、Panasonic、Generac. Among them, the market share of the top five manufacturers has been more than half, and the market concentration is high.

1.Tesla

Founded in 2003, Tesla (TSLA.O, THE United States), relying on Japan’s Panasonic terpolymer lithium battery technology, combined with its own experience in BMS and energy storage system integration, developed an home energy storage system (6.32%) for home, commercial and utility users in 2015 and formally entered the home energy storage industry.

Among them, the Tesla Solar Roof and Tesla powerwall(battery capacity 7 ~ 13.5kWh)are for home use, and the commercial part is mainly medium-sized energy storage battery Powerpack (industrial and commercial for small public; With a maximum power of 130kW and a storage capacity of 232kWh) and Megapack (large utility, energy generation).

Tesla powerwall home energy storage has been in short supply, lithium battery supply has been in short supply. 100,000 tesla powerwall home energy storage (13.5KWh each) were installed in 2020, and Tesla raised the price from $6,500 to $7,000 and then to $7,500 last year. Mr Musk recently said there was a chance of selling 1m tesla powerwalls on an annualised basis next year, close to 20,000 a week.

Tesla powerwall home energy storage has strong competitiveness in the Local market of the United States, almost occupying more than 50% of the market share in the United States. In 2021, Tesla, Enphase Energy and LG Energy respectively occupy 33%, 31% and 21% market shares in the US home energy storage market, and CR3 is up to 85%, indicating high industry concentration.

At tesla’s general meeting of shareholders in 2020, Musk said he was very optimistic about the “photovoltaic + energy storage business”, and said that as the supply of auto parts is in short supply this year, the powerwall odm company has allocated limited resources to cars, and the home energy storage business is expected to develop vigorously next year with the easing of supply.

From the perspective of Tesla’s energy storage installation, energy storage installation has a certain seasonality, and the third and fourth quarters usually show the peak season. In a single quarter, the second quarter of 2021 has a significant increase of 204% year-on-year to 1274MWh.
