  • Tesla unveils batteries to power homes

  • US electric carmaker Tesla Motors has unveiled batteries that can power homes and businesses

  • as it attempts to expand beyond its vehicle business.

  • Chief executive Elon Musk announced the firm would build batteries that store solar energy

  • and serve as a back-up system for consumers during blackouts.

  • The device would allow consumers to get off a power grid or bring energy to remote areas

  • that are not on a grid.

  • Tesla plans to start shipping the units to installers in the US by this summer.

  • In a highly anticipated event near Los Angeles, Mr Musk said the move could help change the

  • "entire energy infrastructure of the world".

  • "Tesla Energy is a critical step in this mission to enable zero emission power generation,"

  • the company said in a statement.

  • The rechargeable lithium-ion battery unit would be built using the same batteries Tesla

  • produces for its electric vehicles, analysts said.

  • The system is called Powerwall, and Tesla will sell the 7kWh unit for $3,000, while

  • the 10kWh unit will retail for $3,500 to installers.

  • To help comparisons, Tesla provided estimates of how much energy is used by different devices

  • in the home. A flat-screen TV uses about 0.1kWh, a tumble dryer 3.3kWh and a laptop 0.05kWh.

  • Energy comparison firm USwitch estimates that a small family in a three-bedroom house in

  • the UK uses about 3,200kWhs of electricity a year.

  • Mr Musk said the company would partner with SolarCity to install the home batteries, but

  • there would be more companies announced. Mr Musk is SolarCity's chairman and largest

  • shareholder.

  • The sales of battery storage systems for homes and businesses could yield as much as $4.5bn

  • in revenue for Tesla, according to Deutsche Bank.
