Tesla has announced that it produced its one millionth Powerwall. An impressive milestone that is, unfortunately, overshadowed by some questionable math.
Powerwall is by far the most popular home battery pack system, especially in North America.
It has popularized residential energy storage and made it now ubiquitous with new rooftop solar energy installations in the US.
Tesla managed to significantly ramp up production and installations in the last few years.
In June 2023, Tesla announced that it had installed 500,000 Powerwalls since launching the first version of the product in 2016.
After launching the Powerwall 3 last year, Tesla claimed that it was now producing 700,000 Powerwalls per year.
However, we were confused a few months later when Tesla celebrated producing 1,000 Powerwalls in a single day, considering 700,000 units in a year is twice as many.
Now, Tesla has announced that it has built its one millionth Powerwall:
Here are the timelines of Tesla’s milestones regarding the deployments and production of the Powerwall:
It took Tesla roughly two years to go from 500,000 to 1 million Powerwalls despite claiming to be scalable of producing over 300,000 units per year since 2023 and 700,000 per year since 2024.
We recently noted that Powerwall is not only a highly popular home battery pack, but it is also a best-selling solar inverter, as the latest version, Powerwall 3, includes an inverter.
Electrek’s Take
Kudos to everyone involved in achieving this milestone. It is impressive, and I think Powerwall is a great product.
It’s just sad that it is hard to trust Tesla these days, and the math doesn’t add up here, as explained in this article.
I might be reading too much into this, but it’s my job to track Tesla closely, and therefore, I do note those inconsistencies.
It will be interesting to see what happens with the Powerwall program in the coming months and years with the tariff situation as the product currently relies on battery cells imported from China.
