Elon Musk’s Tesla Motors company officially announced the upcoming release of a product, a 7 or 10 kWhr household battery that it calls the Powerwall:


The rechargeable Lithium ion based battery leverages Tesla’s current expertise and manufacturing resources in this area for it’s electric cars, and targets owners of residential solar panels.

In states like Arizona and Wisconsin where there will be significant fees on solar owners to hook up to the grid, owning your own source of energy storage to deal with solar intermittency will look more and more attractive to solar-owners going forward.
