CSR in Tesla deal to sell Powerwall

By Angela Macdonald-Smith December 14, 2015, 2:50pm

CSR Bradford expects to charge "under $10,000" to supply and install a 7 kilowatt-hour Powerwall. Tesla
CSR has expanded into home batteries, sealing an alliance with the world's best known battery maker Tesla Energy to sell the Powerwall system to Australian households through its Bradford division.

Anthony Tannous, executive general manager of CSR Bradford, said the move to broaden the product range came after keen interest from both home building developers and directly from consumers and was a logical add-on to the company's solar business.

"This for us was a perfect fit," he said. "We think there is going to be good interest in the new home market as well as the retrofit market."

CSR Bradford expects to charge "under $10,000" to supply and install a 7 kilowatt-hour Powerwall, with installations beginning in early 2016, Mr Tannous said.

A complete 4 kWh solar PV system, with inverter and battery could be installed for less than $15,000.

The deal between CSR and Tesla follows last week's agreement between Origin Energy and the Californian company that will see Origin sell the Powerwall system as part of an integrated package involving a battery, rooftop solar panels and an inverter.

Tesla is understood to be close to tying up other deals to broaden its sales channels in Australia, and is also accepting direct customer orders on its website.

Australia is seen as a prime target market for battery suppliers because of the high penetration rate of rooftop solar, which allows households to make greater savings on energy use when combined with a battery.

Mr Tannous said CSR Bradford, as the country's largers manufacturer and reseller of insulation products that had expanded into solar photovoltaic panels and solar how water, had been considering going into batteries for some time.

"We've been looking at batteries for the last two years and from our research Tesla is probably the pick of the lot," he said, pointing to data on the amount of power the systems can hold and their performance on discharging electricity.

He said Tesla's electric vehicles were evidence of the effectiveness of Tesla's battery technology.

"To be honest, probably the thing for me is that they've got a  battery powered car out there that has been going around for a while - It's probably the only system you can test-drive!" he said.

High costs are still an issue for home batteries, resulting in payback periods of perhaps 8-9 years using a battery by itself, or six to seven years when combined with solar panels, Mr Tannous said, estimating the payback based on his own home in Sydney and using current electricity charges.

He said it was too early to give battery sales targets.

unfortunately at $10k it's not economical at this stage :(  well that sucks :(

System is still too small and too expensive for most users IMHO. I don't think people realise that there have been gel pack batteries available for solar storage for a couple of years now. The batteries are much bigger and heavier and nowhere near as pretty as the Tesla lithium package; but you get more Kw of storage for any given $ spend. I have 24kw of battery storage (battery cost about $22k) which when combined with a 10kw solar system is enough to run a big air-conditioned 2 story house and an electric car for about 4 days in a "mains off" test last month.

and as you say Scott, it's too small. 7kw wouldnt really run house off grid for very long.

what life will you get with the batteries?

The life of the batteries is largely determined by the charge/discharge cycles. If it is set up right and you work them within the optimum range they should last over a decade. My solar guy reckons much longer; but we shall see.
If you blast them to full charge and run them constantly to full discharge you will nuke the batteries in no time.

The other factor to consider is that this technology is in its early stages and prices will come down over time. Think computers in the 1990's or the first plasma TV's.  By the time my batteries die the replacements will be much better and much cheaper.
