tesla ceo elon musk unveils home battery; is $3,000 cheap enough? - home battery system
To overtake the electric vehicle market, Tesla announced it would start selling large batteries to store electricity for homeowners.
The Powerwall home battery starts at $3,000.
Tesla CEO Elon Musk released the new battery on Thursday night, a much-anticipated and speculation.
The surface of Powerwall is smooth, with a depth of only about 7 inch, and can be installed on the garage wall or on other surfaces, either indoors or outdoors.
4 feet high and 3 feet wide.
Explaining the company's strategy to use solar power, Musk said: "We have a convenient fusion reactor called the Sun in the sky.
You don't have to do anything; it just works.
"The device is aimed at homeowners who want to do any combination of three things: store backup power, minimize peak-
The time to use electricity is completely out of the commercial grid.
Powerwall is considered to have (or want)solar panels.
When the sun does not come out, the big battery can supply or replenish the energy needed by the family.
On its Powerwall website, Tesla said: Musk said Tesla is now taking battery orders and added that the first deliveries will be completed in three to four months.
In recent days, the details of the new battery project have become the subject of speculation, from Tesla reshaping itself as an energy company to the cost of the project to homeowners.
Powerwall prices range from $7 KW to $3,000
The hourly model of the 10 KW-hour version and $3,500.
These prices do not include DC-to-
AC power inverters or installations, but still far below an analyst's $20,000 estimate of NPR's Steve Henn in the days before Tesla's announcement.
In a report on Friday morning's edition, Steve told Tesla's partner, JB Straubel.
With regard to the founder and chief technology officer of the battery, the company hopes that this will help to completely change the grid.
From Steve's story: Steve also spoke to battery skeptic Robert Bryce, a writer and homeowner who said the battery had to be very cheap for him.
Forbes writer Christopher Helman said with a 7 KW-hour or 10 KW-hour configuration, "This means that the 10 KW-hour system can provide 10 hours and 1,000 watts for your home.
But after analyzing the costs and benefits of the system, Helman added, "If you don't have a solar system large enough to get your home completely out of the grid, then, it doesn't make sense to pay 30 cents per kilowatt hour to get power through Powerwall.
"For many, it remains to be seen whether Tesla's starting price of more than $3,000 is enough to increase the economy of solar energy.
BBC reporter Richard Taylor believes that "Elon Musk's use of Tesla's expertise in high construction is a strong business reason --
Put them in efficient car batteries at home.
But he added, "The business strategy is a bit like the battery itself: the impact is great, but the release is slow, and it will only bring significant benefits over time.
