Tesla Says Powerwall 2’s Return Will Be 8-15%. Really?

powerwall spruiker

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…]

Will it be illegal to install a single phase Powerwall 2 from Thursday?

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…]

Billionaire’s Gambit – Why we should accept Musk’s offer.

deal

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…]

The full spec and warranty of the Powerwall 2 reveal a cost per warranted kWh almost half that of its nearest rival.

[Update 13th March: 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…]

Why over hyping batteries hurts the solar industry.

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.

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…]

Keith De Lacy Is Not Right About Solar And Wind Power – Not Here, Not Anywhere

article

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.
