By the end of 2015, Tesla’s Powerwall will be made available. While no companies have been specified, Tesla has said a “growing list” of its energy partners in Australia will be able to help customers get the super-power battery for their houses, as reported by Dispatch Times.
The Powerwall, essentially a lithium ion battery module, stores backup electricity from solar panels. Charged during off-peak hours, the stored electricity is then provided during peak hours. First unveiled in May in the U.S. by Tesla chief executive Elon Musk, the company said that Australia is an ideal location for the launch of Powerwall because of its escalated power costs and solar resources. “Our goal is to fundamentally change the way the world uses energy”, Musk said in May.
According to CNET, the Powerwall was launched in the US in 7- and 10-killowatt hour modules, which were priced $3,000 and $3,500, respectively. This was clubbed with an industrial 100kWh Powerpack.
Tesla’s push to introduce Powerwall in Australia has lowered local prices of battery storage products, according to a June study by Bloomberg New Energy Finance. These products include the Samsung device that is marketed by Solar Juice, and an AU Optronics storage device marketed by AGL Energy in Queensland. The study also suggested that there will be 33GWh worth of storage, along with 37GW of rooftop solar, within the next 20 years in Australia.
“Powerwall will enable solar customers to store solar energy they produce during peak sunlight hours with a newly announced power of 3.3kW, continuous and peak,” the company said. “They can then use this energy in the night time hours, rather than purchasing electricity at the retail price and selling their solar back to the grid for the feed-in-tariff rate.”
The 7- and 10-kWH Powerwalls will be made available locally, the company announced. While the former is expected to sell more among users looking to manage peak and off-peak energy use, the 10kWH will be targeted for ruler properties as a backup solution.
