Tesla Powerwall alternatives ?

???  You've gone from $7,500 to $15,000.  Lol, you sound like me.

 

I didn't suggest the $7500 though, that was @awayward

 

I only said it was the cheapest 10kWh I've seen installed  but doesn't include the solar panels of the $15k system

 

I never said that's what I'm getting

More capacity on cloudy days? 

 

Yes depends on area obviously

My solar produces more energy than what I use during winter anyway. 

 

Nice , depends on area obviously

 

Some of us are in really cloudy areas, some have not much cloud

 

Everyone will be different

Are you sure that's an issue that you need to overcome by doubling your spending?

 

This is all discussion to look at options out there. I'm sure the discussion will help others

 

Haven't committed to anything yet so far in this thread

 

I need to look at my solar on cloudy days more closely - with a 12kW panel system you have more chance of outputting 5kW than with 6kW, on dark and cloudy days. But everyone will need to look at their particular case, depending on area , panels efficiency etc

 

Sungrow is better supported in Australia - so there is more than just price, as we've discussed above

You can also lose everything with shares

 

Or lose everything with LG batteries ! 

 

Why can't we have it all

Given your 10 year time frame put the money in an index tracker and use it to pay your power bills.

I don't have a 10 year time frame? That is simply the warranty period.

 

 @BugPowderDust has calculated 6.5 year payback, which is much less than 10 years

 

And index tracker won't help you in the case like him of multiple days of power outage

You can actually set the battery to top up during cheapest offpeak rate also

 

There are some using this method without any solar and saving a lot

 

And you can still get around this a bit by having more extra battery storage

 

i already have solar, so of course would use it 

Is anyone using Amber Energy? Their model is a $15/month subscription that gives you wholesale electricity rates. The concept is that you charge your battery with solar during the day, run it down during night-time peak (your use, and uploading to the grid), then charge fully overnight when prices are cheap, then run down again in the morning peak (your use, and uploading to the grid). By downloading cheap energy then selling back to the grid, you're making money every day with your battery. 

 

Obviously there will be more wear and tear on the battery (2 discharges daily), but it would be good to hear of real-world experiences if someone is using them.

In W.A. when I was looking if I got a 6.6KW system or lower then you get money back on what you feed back to the grid. Not that much though.

In my area the biggest you could go was 8KW before you need to apply to the council for anything bigger. No money back on what you feed back into the grid.

 

Just read that things might be changing and some energy providers are looking at charging people extra for putting back energy in the grid.

If this comes about down the track, the bigger you get, then more you might pay for each KW back to the grid.

@rand129678 I do solar/battery design for a living. I’m not in nsw but if you’re still looking into this shoot me a pm and I can maybe do some proper analysis for you

[Addicted to music]

Not that I have a liking for Tesla, but there are advantages with the Powerwall 3 that’s due and is worth the wait if you are thinking about solar and battery as this has a inbuilt 11.5kw inverter that has 6 MPPTs.   Game changer in cost if I’m reading it right

I've had a Powerwall for years.

I can't see how it could ever pay for itself in outright terms, but it lightens the grid load at peak times completely of my needs, and when there is a blackout, we don't notice. And there was a three-day blackout a couple of years ago. That was worth a lot to me in high summer...

Sungrow inverters and batteries. Good value.

[proftournesol]

We use GenZ LFP 3kWh modular batteries, about $1k per kW, installed. GenZ is a Perth-based company. The beauty is that each module is self-contained; one failure and the rest function normally, and we can add additional 3kWh modules as finances permit. Ours are DC coupled to a 9kW roof PV array, through a Selectronic SP Pro.

Good time to look at the Tesla PW2 as they are now having deals to clear them out of warehouses to make way for the PW3.

As I said I currently generated 3x more power than I use.

 

10kWh will be more than I currently use - I know my useage is under 10kWh daily because I see it on my bill

 

Current bill is $1500 a year.

 

So if the battery stores all the power I need (and more...)

 

Then it is simply $7.5k/$1.5k = 5 years

 

Where is my maths off?

 

if electricity prices increase, it will pay itself off quicker

I guess, you have small family or single??? On which provider are you? AGL ?

Point of having battery is to have electricity when system is down and need lights to defend zombies.....

 

I have inverter which is supposed to give you half of power when grid is down, but last time of blackout was cloudy so I had none electricity.

That is only one use of the battery. People with batteries like those in this thread will tell you just as good other points of a battery.

 

Like avoiding/reducing peak hour electricity consumption...

Sounds like you need a big battery lol

Not for me…. Solar provides power to charge during the day and power various sod around the house. The battery provides power at night time. That’s about it for me.

Ok l know what l said in my earlier post.

 

Ordered a Powerwall 11 from a well known company this morning.

Another factor came into it, retirment.

Had to spend some money on the house. and that savings pays for half of it.

 

And l am putting a Chev sticker over the tesla badge.
