Tesla revealed that the cumulative number of installations for its Powerwall home energy storage systems has exceeded an astounding 500,000 units. This impressive achievement firmly establishes Tesla as the industry leader in the rapidly expanding sector of home energy storage.
Surpassing the previous milestone of 250,000 units reported on November 17, 2021, Tesla has successfully installed an additional 250,000 Powerwalls within a remarkably short span of just 18 months. Such a staggering growth rate suggests an average annual output surpassing 150,000 units and, according to some reports, possibly even twice that figure.
The latest iteration of Tesla’s Powerwall boasts an impressive usable battery capacity of approximately 13.5 kilowatt-hours (kWh), with a total capacity of 14 kWh. Furthermore, it delivers a continuous power output of up to 5 kilowatts (kW), and an impressive 7 kW for brief 10-second bursts.
For those seeking an even more advanced and integrated solar battery system, Tesla offers the Powerwall+. This exceptional unit comes equipped with two distinct inverters—one for the battery and another for solar energy. With a nominal energy capacity of around 13.5 kilowatt-hours (kWh), the Powerwall+ provides an independent continuous power output of up to 7 kilowatts (kW) when operating off-grid. However, when combined with a solar system under full sun, it can achieve an astonishing off-grid power output of up to 9.6 kW.
With a combined Powerwall capacity of 500,000 units, the total energy storage potential amounts to an estimated 6.8 gigawatt-hours (GWh). It is worth noting that the actual figure is slightly lower due to earlier versions of the Powerwall having different battery capacities, such as 7 kWh or 10 kWh.
The cost of Tesla Powerwalls varies depending on the specific model, market conditions, and the number of units being installed. It is crucial for customers to also factor in the associated installation costs when considering their investment.
To provide a perspective on pricing, a single Powerwall unit in the United States may be priced at approximately $8,700. However, it is important to highlight that the cost per unit decreases as the number of units increases. For instance, a bundle of three units could be procured for less than $24,000. Tesla has also acknowledged the presence of various incentives and, notably, a $500 rebate currently available to eligible customers.
