Sonnenbatterie, the battery company that recently poached Tesla’s top German team, is announcing an all-in-one residential PV and storage system for €9,999 ($10,645). Sonnenbatterie is expecting to launch the community initiative today with its 8,000-strong customer base. Schröder said this community exchange model, rather than Sonnenbatterie’s pricing, was the key part of today’s announcement because of the benefits it brings to storage customers. “This model of sharing electricity makes conventional utilities in Germany obsolete,” he said.
