The electric car company Tesla wants to make people independent of the mains. With the help of their new powerful battery and solar panels on the roof they hope that more people's homes and businesses will be able to become self-sufficient of electricity.
The owner, Elon Musk, hopes that both individuals and large companies will start using this renewable energy from Tesla Energy's new product PowerWall.
- Our goal is to change the way the world uses energy in an extremely large scale, said entrepreneur Elon Musk in his presentation at Tesla's design center in California.
To the sounds of heavy rock and a cheering crowd, Elon Musk presented the new batteries. Solar electricity could mean a lot for the inhabitants of the poor countries where power outages are common. The battery storage capacity is so huge that periods without sun do not break the supply of electricity. It stores energy in the panels during the day's sunny hours for use in dark periods.
Elon Musk hopes that the battery will experience the same trend as when mobile phones did the continued expansion of fixed telephony redundant.
The battery is connected to the internet and can be used as a backup power source for the home, or, provided that your house has solar panels on the roof, to make it completely independent of the power grid.
What's new about this? Solar energy has been here for years.
For $3,000 the customer receives a battery with a capacity of 7 kilowatt hours (kWh), equivalent to around 70 hours of television viewing or the energy required to vacuum for seven hours.
The battery will come in two variants, a Power Pack for the household that is approximately 1 x 1.5 meters wide and 15 centimeters thick in an elegant shape and various colors for hanging anywhere in the home. A larger version of PowerWall for companies, with 100 kWh, is also underway. The factory that will manufacture them is now being built in Nevada, USA, and is expected to be completed next year.
A wall of these, well do the math.
- We have this handy fusion reactor in the sky called the sun. Without us having to do anything, it works, said Elon Musk when he introduced the product. A product he hopes will sell in two billion copies, which would be required to transform the world's energy supply.
In his utopian vision, 160 million PowerPacks could provide energy to the United States and two billion units will solve the world's energy needs.
That Tesla would introduce a new product, and that it was about batteries, have been a secret for months.
