Hi guys,
I’ve received a quote of $21,000 (after rebates) for a 10.56kW solar system with a 12.8kWh Sungrow battery in NSW. The package includes:
Just wondering if this pricing sounds reasonable for the current NSW market?
Yeah I reckon I need to get more quotes for this. I just got one to test the water… looks like it's not good enough
Also, did they come to your place to quote, or just quote based on a desktop assessment?
Definitely get more quotes. How much electricity do you use per day? The battery seems a bit low to me - might only provide a day's worth of power.
might only provide a day's worth of power.
wouldn't it be mainly for use when it's night?
Good question. You made me rethink what I wrote. It really depends on OP's usage which could be a lot on the size of the home and there could be poor conditions which limit the amount of solar recharging the battery.
I think going a bit bigger is better because reduces the overall cycles of the battery.
Yeah I reckon the battery is too low, we use 30kwh in normal and around 40kwh+ a day during winter, mostly heater at night time
It might not be a bad idea to consider solar first and then wait for V2G with EVs.
Depends on your use case, but an EV sounds like a terribly expensive battery.
If it gets takes you to work, and you can charge it at work, it might be an option. Seems a niche market that would suit though.
Am I missing something?
@SlickMick: For the cost, it's a lot better value especially for used EVs.
For example, a used Atto 3 with a 60kWh battery can be had for $30k-35k(new is $45k). BYD Seal has a 80kWh battery for $53 plus on road costs. Someone in the thread paid $20k two powerwall 2's for 20kWh pre-rebate. Price wise, it seems to me that EVs have cheaper batteries.
Hopefully the price of home batteries comes down.
I have a similar size system but use 1/2 the power. I guess you could consider doubling the size if you have the roof space.
You need to consider what you're trying to achieve. Do you want to store enough power even for winter nights? For days of low production?
Panels are cheaper than batteries, so I'd focus on generating enough power even on poor days over storing power to cover no production.
(But I'm in CQ, so maybe poor production days are more of an issue for you??)
I would aim to generate and store enough power on an average day to get through a normal non-winter night, and expect a power bill in winter and poor weather.
The battery seems a bit low to me - might only provide a day's worth of power.
I agree. I have 27kWh battery and relatively small 5.4kW solar and if you get a run of several rainy or overcast days in the winter months the battery can't keep up to provide 24hr supply. We use around 300kW/month
If I was doing it again I'd aim for 40kWh.
How much did that cost you?
Pre-Federal rebate. 2x PW2 around $20k
Depends on what you're trying to achieve. I don't think batteries are affordable yet to cover days of low supply. I'm only aiming at covering overnight consumption.
I'm happy to use the grid when I can't produce power. If I couldn't rely on the grid, I'd look at getting a generator before trying to store enough power for multiple days.
Does that system usually keep your battery full? I'd have thought more panels would be a better solution for you than more batteries.
Oh, and I wouldn't consider that cheap, but it is ball-park. I think you'll find a better deal.
@SlickMick Who are u replying to?
If me:
I didn't say my PW2 were cheap, especially in the current market where there are more choices and a larger government subsidy.
A generator would be a great back-up if the circumstances permitted. In my case the main breaker & meter is in a basement carpark and the sub-board is in my kitchen. Both options have an issue with where to vent the exhaust gas.
I'd love more panels but I have a total of 40sqm roof space and 8sqm is unusable due to shading & skylights.My roof is crammed. 5.4kW is definitely less than ideal.
@brad1-8tsi: You, I was just saying 27kWh battery is plenty for normal overnight consumption, but you seem to want to store enough to get through non-normal periods. I was just saying it would be nice to store a few day's consumption to get through bad weather etc, but it's just not affordable to do that.

How long will it take to get back your investment, including any maintenance costs over the period…
maintenance costs??? Like cleaning the panels once every 5 years?
all maintenance costs, including replacement of parts/batteries etc.
Everything has 10 year warranty at minimum
that is enough to recover costs.
@jv: That's a problem 10 years later.
If I have recovered costs, then I might just rip and replace as the tech would be much better.
Typically one should recover costs between 5-7 years max
just rip and replace as the tech would be much better.
Could be more expensive.
Also, you're not taking into account the 'cost of money' over that period, or how that $20K could have benefited you more, rather than just 'recovering your costs'…
Typically one should recover costs between 5-7 years max
Doubt you'd get it back in that time if purchasing a battery.
@jv: I get your point but there are a few things to also consider:
My daily usage is circa 30KW, but my battery is 40KW - I want extra to sell back to Amber for quicker recovery/cater for degradation.
Yes I could use the $20k to grow however you should also consider the increase is electricity prices over the coming years, which have been a shock lately.
The modelling provided in my proposal shows the timeline of recovery. Of course few assumptions are taken into account.
Over all I am happy to pay that amount and almost be off grid.
You may have other factors and that's ok as well…
How long will it take to get back your investment, including any maintenance costs over the period…
I'm calculating 12 years at the moment but have just shifted to Amber and hoping to reduce that to 7-9 years.
There isn't really any maintenance involved.
What about replacing the batteries?
Warranty for the first 10 years with a maximum degradation level.
If they crap out after that I'll put it down to poor decision making on my part. Sometimes you have to take a punt.
Not cheap enough, I know sungrow is on a bit of higher end but that's a lot for just 12kwh of battery. To give you reference I got local installers around me offering $12k for 20kwh sungrow battery. 13.2kw Solar system alone should be around 10k in itself but if installed as a package you'd expect some discount.
That sounds like a get fcuked quote.
Would be cheaper to by a V2G car and permanently plug it into the wall.
hahaha that is a power move. i don't think cars have gotten that cheap enough that we will see this happening. maybe when they hit $25k. $25k for a 45kwh battery with wheels sounds ok to me.
Let me introduce to you deprecation….2023 Atto3's can be had for $30k already.
Does the capacity of the battery depreciate too?
@tenpercent: ~25% for the car in 2 years, the battery couldn't be more than a few % in that same period, most models on have ~40k on them.
@tenpercent: Yes but not at the same rate. It varies by battery tech, usage, age and a bit of luck.
This website says that after 200,000km some batteries are down to 75% efficiency. For a 60kWh battery, that's still 45kWh of usable electricity. Tesla's from 5 years ago are selling for half price - $30k and not have done that many km.

Getting a 48 kWh SigEnergy Sigenstor with a 12kW inverter - $20k after the rebate
I'm getting the same, however the inverter size is 24kW for $19.5K after rebate in NSW
I'm going 32kWh Sigenstor with 25kW inverter (3-phase), $~20k after rebate. 24kWh V2G PHEV coming later!

if your bills are like $3-4k a year then… I think it makes sense to go solar

I just got a quotation today for a 20kWh ESY battery for a three-phase connection - $6,500 out of pocket.
Seems a little high, what quotes have you obtained from other companies?
Installation requirements can vary substantially from house to house. So what I paid or what someone else paid may be only a vague guide to what it should cost for your place.
Therefore you cant tell if its above market unless you have other quotes from the market
