Tesla, under the leadership of South African-born Elon Musk, last week revealed that it will sell batteries capable of powering homes and/or businesses.
The battery in question, named, the Powerwall, was termed by Musk: “To be a fundamental transformation of how energy is delivered.”
The Powerwall charges using the electricity generated from solar panels. According to Tesla the idea is that the battery generates energy during the day when the sun is at its peak and delivers the electricity during peak-demand time zones.
The residential battery also has the added advantage of being a backup electricity supply when unexpected load shedding occurs. In the event of an electricity outage, the Powerwall automatically switches to battery energy.
Transferred from Tesla’s automotive lithium-ion battery technology, the Powerwall can store 10kW hours of battery charge while several batteries can also be connected together. Setting the Powerwall technology apart from existing batteries is internet connectivity – enabling users to monitor and effectively use electricity stored by the Powerwall.
Pricing for Tesla’s electricity solution starts at US$3 000 (36 000 ZAR).
