Tesla’s Solar Panels to Be Sold Only With Powerwall

Tesla Inc.’s solar panels and roof will only be sold together with its Powerwall battery, according to Chief Executive Officer Elon Musk, as the company seeks to convince investors and users of its viability in the residential energy technology sector.

Solar power from these panels will feed exclusively to Powerwall, he said in a series of tweets. The Powerwall will only interface between utility meter and house main breaker panel for simple installation and backups during utility dropouts, Musk said.
