Tesla’s Battery Put in the Shade by Current and Cheaper Kit
7th May 2015
Courtesy of Bloomberg, the world gets an idea of what the retail from-the-installer price of the battery might look like (rather than the wholesale price the ‘leccy car maker announced last week).
The Elon Musk-led system seller SolarCity, Bloomberg reports, will ship an installed 10 kWh Powerwall for US$7,140 (ouch outright purchase) or $US5,000 plus a nine-year lease.
To match a 16 kW generator that sells in the US for just US$3,699, the reporter works out, would require around US$45,000 worth of Powerwalls on the lease deal.
Bloomberg New Energy Finance doesn’t imagine the Powerwall making a dent in European markets like Germany, where the economics of solar power are well-understood. Its take is that “the economics of an average home with rooftop solar are not significantly enhanced by including the Tesla battery”.
