Elon Musk says that Tesla is “working hard on increasing Powerwall production”, as delivery delays are extending into 2021.
California has strong incentives for installing residential energy storage capacity that has created more demand than Tesla, the market leader with the Powerwall, can handle right now.
Earlier this year, Tesla announced that it installed its 100,000th Powerwall home battery pack.
But Tesla is not the only one installing Powerwalls.
The company is also supplying the home battery pack to hird-party solar installers.
Several installers reached out to Electrek over the last month about longer than usual delays to get Powerwalls from Tesla.
Some installers told Electrek that orders that were already in place are now showing delays into Q1 2021.
In response to those delays, Tesla CEO Elon Musk said on Twitter today:
“Tesla team is working hard on increasing Powerwall production.”
The CEO didn’t suggest a timeline for a production ramp, but he confirms that the company is working to fix the supply constraint.
Last quarter, Tesla deployed 419 MWh of energy storage, which includes Powewalls, Powerpacks, and Megapacks.
A lot of people are speculating that the delays might be due to a Powerwall version 3 being announced at Tesla’s Battery Day in September.
Personally, I doubt it. I don’t think it’s impossible, but we have been reporting on supply issues with the Powerwall for a while.
I think it’s a more likely explanation.
Furthermore, Tesla focuses Powerwall supply for its own solar installations and I think those are increasing right now with the recent price cuts.
Combined with increased demand from third-party installers, the demand is probably off-the-hook for Powerwalls right now.
