But now, things might change. Tesla Motors will sell a big home battery this fall, it seems, based on the technology they developed to hold their cars' charges.
It might work like this:
“We are trying to figure out what would be a cool stationary (battery) pack,” Forbes had quoted Musk as saying at the time. “Some will be like the Model S pack: something flat, 5 inches off the wall, wall mounted, with a beautiful cover, an integrated bi-directional inverter, and plug and play.”If that works, and if it's affordable, unlike the Tesla, the battery is something for us to look into once we can make progress generating our own electricity.
