Despite Solar Roof’s problems, Tesla’s Powerwall has apparently been a hot product last year. The company announced on Twitter that it has sold more than 200,000 Powerwall units so far, roughly double its sales at this time in 2020.
When the power is off, Powerwall can provide powerful backup batteries for solar panels and other customers. As Twitter user Andru Edwards pointed out in a tweet quoted by Tesla, this saved some customers during the power outage.
He said: “My neighbors started texting to ask how my lights are on.”
Tesla CEO Elon Musk also suggested that during the storm that hit Texas in April, power Utility companies may be able to use Powerwalls to release stored electricity back to the grid in the future.
If it can manufacture a greater number of products, it may obviously ship a greater number of products. Tesla recently stated on its first-quarter earnings conference call that it had a backlog of multiple quarters on Powerwall.
It also announced in April that without the Powerwall division, it would no longer sell its Solar Roof panels, which should further stimulate demand.
This will allow people to power more things or larger houses, although the battery can still maintain 13.5kWh of power, but the power consumption will be faster.
