The long term plan of Tesla CEO Elon Musk to establish a widespread energy solution might finally be coming to fruition. After the public adoption of his electric cars, the Tesla Model S and Roadster, Musk has now moved on to the release of both a battery for residential use and a larger battery for industrial application, called the Powerwall and Powerpack, respectively.
Powerwall is a rechargeable lithium-ion battery designed for energy storage for residential consumers. According to Tesla it is primarily designed “for load shifting, backup power and self-consumption of solar power generation.” Two variations of the Powerwall have been released: a 10 kWh model which is listed at $3,500 and a 7 kWh model listed at $3,000. Their big brother, the Powerpack, is expected to be released in 100 kWh capacity blocks and is designed to be scalable from 500 kWh to 10 MWh.
