Tesla announces low-cost batteries for homes

02.05.2015 | The Guardian | www.guardian.com

The electric car company Tesla has announced its entry into the energy market, unveiling a suite of low-cost solar batteries for homes, businesses and utilities, “the missing piece”, it said, in the transition to a sustainable energy world.

The batteries, which will retail at $3,500 in the US, were launched on Thursday at a Tesla facility in California by the company’s ambitious founder, Elon Musk, who heralded the technology as “a fundamental transformation [in] how energy is delivered across the earth”.

Wall-mounted, with a sleek design, the lithium-ion batteries are designed to capture and store up to 10kWh of energy from wind or solar panel. The reserves can be drawn on when sunlight is low, during grid outages, or at peak demand times, when electricity costs are highest.
