Finally the Tesla’s founder  Mr Elon Musk introduced its new business called “Tesla Energy” , this new business is focused on ending our dependence on grid power and switching instead to solar energy.

The first product from the tesla energy is ” Tesla Powerwall” . This is  a stationary battery that can power a household without requiring the grid. The battery is rechargeable lithium-ion – that comes in a 10 kWh version for $3,500, or a 7 kWh model for $3,000. The Unit is about three feet by four feet in size and six inches thick, and comes with integrated heat management and  can fit either on the inside or outside of the wall of your home.

Like regular batteries, they can be used together — up to nine can be stacked up together to create a strong and reliable power source. Musk said he believes they can help people in emerging markets or remote locations ‘leapfrog’ the need for existing power systems, in a similar way that mobile phones have become more important than landlines in remote parts of the world.

“The issue with existing batteries is that they suck and they are expensive, unreliable and bad in every way.”

says Elon Musk

The big brother of Tesla powerwall is called “PowerPack” Musk and his team describe it as an “infinitely scalable system” that can work for businesses, in industrial applications, and even public utility companies, that comes in 100 kWh battery blocks that can scale from 500 kWH all the way up to 10 MWh and higher.

“Our goal here is to change the way the world uses energy at an extreme scale.”

Musk’s ambitions with the battery are tremendous during the event he said that With 160 million Powerpacks, we could power the United States, he said, and with 2 billion, the world. The entire presentation and party, Musk said, was powered by stored solar energy.

“This is within the power of humanity to do, It is not impossible, it is something that we can do. But there’s going to [need to] be other companies involved.”

Musk added that Tesla will continue its policy of open-sourcing patents to help make that happen.


As to the fact even you heard about Powerwall today or its announced today – The Powerwall has been tested for a year, and has already been on sale to select customers. For its big brother PowerPack System , Tesla will start taking orders later this year and then really ramp up production as Tesla’s battery

Musk has made electric cars a (stylish) reality, and is pioneering space exploration with SpaceX. Tesla Energy is another concept which, though beyond the realm of most people’s understanding, has potentially huge consequences if Tesla can execute as Musk believes it can.

“This is a feasible thing, It’s very important to appreciate that.”
