Demand has exceeded supply for Tesla's utility-scale Megapack battery product, according to RJ Johnson, the company's head of commercial energy.
Limited battery cell production has curtailed production of multiple Tesla products, according to CEO and product architect Elon Musk, who spoke of the need to increase efficiencies and decrease costs.
Solar deployment also doubled, with 57 MW installed during Q3 after installations slowed in the first and second quarters of this year.
"We want to step back and rethink batteries from scratch, rethinking the fundamental physics," he said.
With this research and development effort, Musk said, he expects to produce batteries that cost half as much within a few years.
Musk predicted further growth for Tesla's Solar Roof, which he described as a "killer project" with promise to be realized next year.
He also hinted at a concept for a residential storage product that would incorporate energy storage and household heating and cooling "in a tight package.". »
