GCL’s E-KwBe Battery, Or Something Similar, Will Change The World

gcl e-kwbe battery

The GCL E-Kwbe battery may be unpronounceable – but it may also save the world. Kind of.

GCL, a large Chinese company, has unveiled a new lithium-ion energy storage system at a price point that some consider to be shocking. Called the EKwBe, it has a seven year warranty, a ten year expected lifespan, and comes in two varieties. A 2.5 kilowatt-hour system that wholesales excluding GST for $1,499 and a larger 5.6 kilowatt-hour system that wholesales for $2,999.  This is the lowest price that has been offered for any comparable energy storage system and I believe that it, or something similar, has the potential to change the world.

Update: 1st December 20016.  The GCL EKWBE battery currently appears to be retailing for around $3,600 inc GST.  This doesn’t give it a cost per warranted kilowatt-hour as low as the announced Tesla Powerwall 2, but it will be interesting to see if GCL will cut its price further in response once the Powerwall 2 is actually available for installation.

How The Cost Of Powerwall Storage Doubled In 11 Months

cost of powerwall

The cost of a storing each kWh in a Tesla Powerwall is much more than you might think.

 

[Update: on Oct 28 2016 Tesla announced the Powerwall 2 ]

[Update: In June 2016 Tesla updated the Powerwall warranty – details here]

11 months ago Elon Musk jumped on stage and announced the Powerwall.  The Tesla data sheets released after Musk’s presentation proclaimed we would soon be able to buy a 7kWh daily cycling Powerwall for US$3,000. It would be guaranteed for 10 years with an optional 10 year warranty extension available. Treehouse, one of the companies who Tesla announced would be first to sell it in the US declared that $3,000 was the retail price – not the wholesale price and we all went “Wow! Cheap batteries have finally arrived.”. [Read more…]

Powerwall Alternatives That You Should Consider as Tesla Battery Hype Reaches Fever Pitch

powerwall alternatives

Just 3 of the Powerwall alternatives now available in Australia.

Manufacturers of Powerwall alternatives struggled to be heard last week as the mainstream media went crazy over the beautifully stage managed, first residential Powerwall battery storage installation in Australia. 

The mood was one of expectation and excitement — mixed with a tinge of dread in fossil fuel circles – as it heralded the advent of affordable home batteries from Tesla and its many competitors in the home battery market. [Read more…]

Tesla Powerwall vs. Enphase AC Battery

How the Tesla Powerwall and Enphase AC battery specs compare.

In terms of good marketing in Australia, two batteries stand head and shoulders above the rest in Australia right now: the Tesla Powerwall and Enphase AC battery. Both of which are due for mainstream release in 2016.

(There are lots of alternative batteries around – many of which are worth considering – but this article is about Tesla vs Enphase due to the volume of enquiries we get about them.) [Read more…]

We ask five experts: Will battery storage change the way we live?

In the first of a series from SolarQuotes, we ask five eminent experts in the clean energy field to discuss four questions on a selected topic. This month we’ve selected “battery storage” as the launching pad for some fascinating discussion and advice.

Solar and battery storage has been one of the clean energy talking points of 2015 following the dramatic unveiling of the Powerwall by Tesla’s Elon Musk. However as we’ve seen, the Powerwall isn’t the only option out there in the marketplace and the best battery storage option will differ depending on your situation whether on-grid, off-grid or hybrid solar.

With this in mind we’ve asked our experts what these solar battery storage breakthroughs mean for Australian households and small businesses and what the future holds for energy independence. [Read more…]

Does your hybrid solar system really need backup?

Did you know that adding batteries to your solar does not automatically mean it is blackout proof?

The holy grail of affordable on-grid energy storage has finally arrived! Well, it’s almost arrived. Actually, it might be a couple of years before it really arrives and most Australians can get their hands on low cost energy storage systems such as the Tesla Powerwall, but they are coming and they will eventually be here. Adding batteries to your home solar (AKA a hybrid solar system) means that you will no longer be forced to sell electricity for 6-8c and buy it back, at night for 30c. Hurrah!

But when the holy grail does arrive you will have a choice, so take care that you do not choose poorly.

While a bad choice is unlikely to cause you to crumble into dust like the Nazi villain at the end of the second worst Indiana Jones movie*, if you what you decide is wrong for your particular circumstances you may live to regret it. Actually, I can almost guarantee that you will live to regret it, as it is really not a life and death decision. Unless you go about it in an astoundingly bad way, such as cutting power cables with an axe and then licking them to see if they are live, I can pretty much guarantee you will still be around to either rue or feel chuffed about your choice.

Interview: Finn Peacock talks solar battery storage in Australia (and more)

Finn Peacock talks shop with Rich Bowden

It’s been a big year for news on solar battery storage in Australia. With the imminent release of Tesla’s Powerwall onto the market and influential reports predicting a new way of accessing energy, the trend has not been “if” but “when” renewables will end up dominating new energy takeup in the country.

But how much of this is kosher and how much wishful thinking? Are we on the cusp of a solar battery storage revolution? Can we start tearing up our electricity bills? To find out the answers we asked Finn Peacock, SolarQuotes founder (and professional cutter through bullshit), his opinion on exactly what has made 2015 so important in solar power and what his predictions are for the near future.

His frank analysis is fascinating, sometimes controversial and may surprise some. [Read more…]

Tony Abbott vs. Elon Musk

Who do you think has it right – Tony or Elon?

Posted by SolarQuotes on Thursday, June 11, 2015

 

 

Tony Abbott is convinced that solar and wind cannot power an industrial economy. Elon Musk believes it is very feasible to power the entire world with batteries and renewables.

Watch the video above and let us know who you agree with:

Elon Musk announces Powerwall V1.1

Earlier today, in the 2015 Tesla Motors shareholder meeting Elon Musk announced that the Powerwall will be upgraded from 2kW to 5kW steady power output (and up to 7kW peak) and keep the same price. He said that they were responding to criticism that the original 2kW was not enough to cope with the peak power demand of a typical home. [Read more…]
