Is it reasonable to expect a “8-15% return on investment” on a Powerwall 2?
Last month, Lyndon Rive, Tesla’s Vice President for Energy Products, stood up in front of a large group of people, including me, and promised the Powerwall 2 will deliver a return between 8% and 15%. [Read more…]
Unless your local electricity network provides a local variation to a new Australian Standard that becomes mandatory on Thursday, it may be illegal to install a Powerwall 2 plus solar on a single phase. [Read more…]
Last Thursday in a trendy re-purposed Substation near Melbourne, Elon Musk’s cousin Lyndon Rive claimed he could solve SA’s energy woes in 100 days.
How?
By installing 100-300MWh of batteries.
Big Call.
A day later, via Twitter, Aussie tech billionaire Mike Cannon-Brookes asks Musk if he’s serious about “100MW1” of batteries in 100 days. Musk wagers he’ll deliver and install them in 100 days or it’s free. [Read more…]
Look what Santa got for Christmas.

See you next week, with a turkey sandwich and a post rounding up what happened in Australian Solar Land during 2016.
The full spec and warranty of the Powerwall 2 reveal a cost per warranted kWh almost half that of its nearest rival.
[Update March 13: Tesla has cancelled sales of the DC Powerwall 2 in Australia and the first installations of the AC version of the Powerwall 2 will now apparently be done in April.]
Yesterday, Tesla kindly sent me the Powerwall 2’s full data sheet and warranty. We already knew the headline specs:
Storage: 13.5kWh
Power: 5kW steady, 7kW Peak
Price: AUD$8,000 + GST and Installation
But there were lots of questions over the exact configuration and warranty details that could make or break Tesla’s shiny new battery. Most of these questions have now been answered.
Here’s what the new specs reveal: [Read more…]
I feel so strongly about this that I though I’d shout at a video camera about it for 7 minutes. Hit me up in the comments if you think I’m being too harsh.
Simon Hackett with an early customer’s double Zcell off grid system.
Yesterday, Aussie solar veteran Tony Smith left an interesting question at the bottom of our ZCell battery review. Tony asked, for an off grid application, how to handle the fact that the ZCell battery needs to shut down so it can perform maintenance mode every week or so: [Read more…]
A response to Keith De Lacey’s article in the Australian last week.
The Australian recently published an opinion piece by the Director of an oil shale company and former Chairman of Macarthur Coal, entitled, “Solar And Wind Power Simply Don’t Work – Not Here, Not Anywhere“.
This was surprising because the solar panels above my head are producing electricity right now. And since I know exactly how much I paid for them I know they are definitely economically worthwhile. Also, because I know exactly how much the STCs I received as part of Australia’s Renewable Energy Target were worth I know the rooftop solar system would still pay for itself even without subsidy.

How does the LG Resu compare to the Tesla Powerwall?
If you are looking at a 6.4kWh Lithium-Ion battery for use with your solar power system in Australia right now, you are probably tossing up between a LG Chem Resu 6.4Ex and the Tesla Powerwall.
To help you decide which one is for you – here is a side by side comparison, and some commentary on their warranties below. [Read more…]
Duracell has just announced its first product in the home battery storage market – competing directly with Tesla.
Well, it finally happened. After sitting on the sidelines as the solar battery storage boom unfolded around it, the world’s biggest name in batteries has finally joined the party.
Today, April 1, at a glittering press event in Bethel, Connecticut, Duracell’s VP of Solar Storage, George Leclanche, unveiled the Duracell Ultra Lithium Home Battery – which will be available in priority markets including Australia by the end of the year. [Read more…]
