Energy prices are high, the grid is increasingly unstable, and solar panels and giant batteries are more affordable than ever. No wonder Tesla Powerwall sales are accelerating, according to Electrek. But competition is getting fierce, with newcomers like Anker and EcoFlow joining the mix just this week.
In a (now-deleted, as of 12:20PM ET) post, the Tesla Powerwall Twitter account said it had “Just surpassed 500k Powerwall installs globally!” and promised a $500 rebate per unit. The tweet has not been reposted so far.
