Elon Musk has recently announced on Twitter that, Tesla’s solar products will soon only be sold together with the company’s Powerwall battery, Integrating them into a single product will making installations easier and home backup more seamless during outages. The change will affect both Tesla’s Solar Panels (which sit on top of an existing roof), and Solar Roof.
Signs of Tesla’s intention to bundle its solar products with the Powerwall were reported last month by Elektrek, who spotted that the company was only accepting new Powerwall orders when combined with a Tesla solar panel project.
Powerwall supply shortages were thought to be to blame for the shift, with demand and wait times increasing for the home battery solution. In the fourth quarter of 2020, Tesla installed 86 mega-watts (MW) of solar energy, a 59 percent increase compared to the same period the previous year.
Alongside the change, Musk announced an upcoming software update for the Powerwall, which he says will enable upwards of a 50 percent power increase depending on production date.
