It’s been one of the worst-kept secrets for a while, and now Elon Must has officially unveiled Tesla’s ambitious new battery tech that could eventually power your house.
It’s called the Powerwall, and once Tesla actually starts cranking these out in mass production, it’ll represent one of the best and most accessible batteries to actually store energy generated by solar panels. The ambitious new lithium ion battery tech comes in a 10 kilowatt-hour (kWh) model and a 7 kWh model. (Context: Refrigerators use 0.2 kWh, and it takes about 0.1 kWh to light a room.) So, ideally, these could be used to store and power a home at night, or to kick in during emergencies.
The battery (it’s that fancy box mounted to the left side of the car in the above shot) weighs just 220 pounds and is housed in a rectangular case that can be mounted inside or outside a residence. The whole thing is just 7 inches thick, which ain’t bad for a battery. You can also “stack” several of them to power large homes or buildings. The best part? The entry-level battery will cost $3,500, well below the $10,000-$30,000 asking price of comparable batteries from competing companies.
Though this is an ambitious move in itself, Popular Science reports Musk is working to develop a much larger version of this battery that could power businesses and make a real impact in the renewable energy space in the years to come.
