Tesla Powerwall

[fuzz]

Start our build soon and have been trying to figure out a good approach to being somewhat 'footprint' conscious.....plan is solar and a 7kw Tesla.....looks interesting but interested to know thoughts on those who have perhaps gone down this road??? It will be a 4 bedroom house, aircon, pool and all the rest of the gadgets having a young family brings with it...

I'm also reading that the 7kw storage is only able to deliver 2kw at peak output which is not great when you consider the investment cost and there seems to be a suggestion that 2 batteries would be a minimum for homes the size of ours.....ouch$$$$$.

Yep, OUCH is right!!!

What is wrong with a system, when you have to get twice the capacity to get 1/2 the output?

[Symon]

Don't give in to the hype about the powerwall.  Overpriced and underwhelming.

There are plenty of other more affordable systems out there.

Have a look at the Aussie Redflow system.  Had many advantages over the Tesla solution.  Not least it can't catch fire, can be fully discharged without damage.

Here it is:  https://www.zcell.com

Using new panels and new tesla will take about 27yrs to recoupe your money. Plenty of info about too  ( just finished night shift to tied to find links. Just do heaps of research. Solar is still good idea not tesla , as said there are other ways with solar.

but are they as trendy?

I don't think the cells are as easy to come by bulk here in Aus however and you want to make sure you know what you are doing before you play with lithium batteries.

thanks for finding that. I came across it a while ago and couldn't find it again.

One of the later vids is quite interesting. This is the equivalent of 45 Power-walls and it's made from commercially available (in the US at least)

We're looking at zcell or enphase storage, panels will be decided by the storage, solar inverter heat pumps for heating and cooling...

And a product similar to Zego for construction...

Hoping for at least a 7 Star rated home

Batteries do not make economic sense yet
Plenty of whirlpool threads - even guys selling systems say they don't make sense for normal residential houses

Asked my brother who works in Solar and he said batteries don't make financial sense yet if you are on the grid.

With the tariffs now gone, even solar needs some serious thought if on grid.

I'm a solar installer and I see both sides.
Solar is crapola if you are not using the power during the day.
But a lot of people do. I have lots of very satisfied customers who are saving money.
Even just a small system to run you pool and standby stuff is worth it.
As far as batteries go, the price is steadily dropping and now batteries are affordable, and getting cheaper by the day.

A good quality system set up properly will save you a lot of money, but it's like everything else, you need to do your research and talk to professionals.
For some people a cheap chinese camper suits their needs, but to some who are promised the world by a cheesy salesman, then try to live in it for 6 months crossing the country it turns out very bad.....
Solar is no different. Knowledge is the key.
The glossy brochures and salesman speels are for the suckers.
If the bloke talking to you isn't installing it, tell him to keep walking, he's just making coin selling sales leads......

I have plenty of customers I have recommended not to get it, but plenty who I said it would work for and it does.

Cheers

Depends on where you are.  SA has seen a huge increase in prices lately so it would look attractive there, the eastern states aren't quite as bad - yet.

Symon, is that a increase of elect prices ? Product of privatisation ??

As for Brian, I run almost nothing during the day ( pool runs during the night....I'm on smart meter ), so solar now for me ( and yrs left at  present residence unknown ) is probably not viable.

[Hairs]

This interests us greatly, we have 3.8 kw system, and we want to know what/where to go next.

Powerwall is a cult. Like iPhone. Just less useful and priced higher

Apple have been a dominant force for a long time. Now the opposition have caught up ..

Know several people who swore by apple, now have galaxy androids and shake their heads at the lack of things the apple can do.

The powerwall is for people who think they're getting a mini Tesla to bolt to the wall..........must admit it looks nice......maybe they could bring it out in the same different colours of the Tesla ?

Might not be economical in case of $$$ just yet, but I belive that this method will be the way of the future for reduction of carbon emmissions. I think it makes enviromental sense

Maybe??  But for the increased manufacture of batteries, how much more energy needs to be expended to make them.......don't forget they would be manufactured in 3rd world countries ( China, India, Bangladesh )with coal fired power stations !!

The more we use renewables and storage the less of an impact the manucature of these products will create. I dont think goverments really get the urgency of reducing green house emissions - I want a decent world for my kids to live in and at the current rate we are going its not going to happen
China is actively reducing its coal power more than most other countries around the world - with the air polloution they have there wasnt really any other choice. Granted India dosent seem to mind burning coal into the near and far future. Jesus Im sounding like some unwashed hippie

Check out lithium mining and it's environmental impact lately?

give this mob a call. i recently priced a stand alone setup through them, and it was 40 grand, but thats with 50kw of batteries, they use AGM batteries, which i would prefer over lithium, as cost per kw is way better, 7kw wouldnt even last a whole night, as far as i'm concerned if your going to get batteries, get something that will do the job properly.
