"Tesla is not just an automotive company," the automaker said. "It's an energy innovation company. Tesla Energy is a critical step in this mission to enable zero emission power generation."
The Tesla Powerwall, a rechargeable lithium-ion battery unit for homes, will go on sale in late summer at a wholesale price of $3,500 for 10kWh models and $3,000 for 7kWh models. Prices do not include installation. The system uses the same batteries Tesla produces for its electric vehicles.
"The unit mounts seamlessly on a wall and is integrated with the local grid to harness excess power and give customers the flexibility to draw energy from their own reserve," Tesla said.
Edmunds says: Tesla says it wants to help wean the world off fossil fuels and it is expanding far beyond cars to do this.
