Tesla’s solar panels will soon only be sold in bundles with Powerwall

The new policy was announced just hours after Musk responded to a tweet from Ark Investment Management’s director of research Brett Winton, who had complained that his Tesla solar panels hadn’t generated any electricity since installation because he was waiting on his local utility company to approve the connection.

Tesla’s solar products will soon only be sold together with the company’s Powerwall battery, CEO Elon Musk announced on Twitter. Integrating them into a single product will making installations easier and home backup more seamless during outages, according to Musk. The change will affect both Tesla’s Solar Panels (which sit on top of an existing roof), and Solar Roof (which replaces a home’s existing roof slats).
