Looking at Solar for my new house.
I need to convince my wife to go ahead with it and looking at doing some calculations on how much it'll save its.
Looking to see how much people generate and the size of the system.
I am looking at 6kw or so system. I am in VIC too.
I went through solar quotes and got three quotes, but I kept seeing much cheaper quotes on Facebook. There’s a hidden price for using a solar broker… So instead I picked a local mob who had an ozbargain sale, did some research and rolled the dice.
We have a 5KW system and we "export" roughly 15-25kw per day.
Our average daily usage for October was - 11kw (negative 11kw)
22kW per average over a bit over 2 years (summer months ~35 to ~40+). As mentioned in a previous thread re: solar, our household average power consumption (thanks to solar) is ~4 kW per day (that's the yearly average)!
If you can get it, get it (budget and roof space).
Get the biggest size you can fit and afford.
9.6 System, NSW based. Heres a day by day account of the last 5 days,
17 - 51.11
18 -65.8
19 - 67.8
20 - 56.6
21 - 51.6
Obviously we do pretty well from it, that said probably using the AC a bit too much
Looking at the poll everyone is voting wrong by the looks of it (me included!)
Location: Adelaide
Commissioning date: 16/02/2019
Number of module: 39
Module Make: Jinko Solar (39*315W)
Inverter: Fronius
Installation cost: $6250
Total generation till date: 28.87MWh
Presently on 18c Feed-in-tarrif with AGL
Depends on the weather. I've been tracking it for 10 years. Generated 54Mwh
4.8kw system and would average 16 a day over the year

Put your postcode into of output and see what people do in your area.
6KW system depends on the month (obviously) though in the summer months I'll average around 8300kw a month wherein winter it will be around 360kw a month.
8300kw a month
You mean 8300kWh for the whole summer or the year, yeah?
Otherwise we are talking about your system producing at peak power for around 45 hours each day
Hello all,
A solar newbie here.
I purchased my home in melb early this year. We have a 5kW inverter and have 21 solar panels (unsure how many Watts each solar panel generates).
Looking at electricity bill i see we have exported a total 65kwh in Oct (got 10.2cents per kwh for it). In jan 2020, we exported 112kwh.
Looking at how much Solar power people generate, I see something isnt right with our setup considering how many panels we have on the roof.
Questions:
How do u folks determine how much power the solar system is actually generating? my source is my elec bill and power company (jemena) website?
Is Solar power exported = total solar generated at that point of time MINUS domestic use at that point of time. Even at the peak of summer, the maximum i exported per day to grid is 6kWh.
Seeking clarity on how my solar system is setup.
Thanks in advance
we got ours through solahart, and there is a separate app that reports actual power generated, which can be compared to AGL's record of the power sold. so the difference between power generated + sold is how much solar power we used, then AGL tells us how much non-solar power we bought from them.
ok makes sense.
my solar system was installed in 2010 or 2011 by prev owner. Need to find out if our system can report the actual power generated.
yeah i think it might be a bit of a luxury from what people have said, is there an LCD on the inverter? ours reports how much has been generated for the day, you could jot that down for a period to get an idea
@c-tho: yes! there is a small lcd display on the inverter. need to read the manual to work out how to get the total gen info.
Is Solar power exported = total solar generated at that point of time MINUS domestic use at that point of time.
Likely.
How do u folks determine how much power the solar system is actually generating?
From your Inverter. Find out your inverter model, and see if we can look up the user manual.
have 21 solar panels
They may be less generating than 200W each (due to age or they were not high performance to begin with, or a fault somewhere)
5kW system, peaks at about 41-42kWh in mid-summer.
thats solid!
what puzzles me with my system is, we exported just 120kwh for whole of Jan. ours is a 3 person household with avg 7kwh per day usage. im not sure where the rest of the solar power went. id expect 21 solar panels + 5kw inverter system should generate more 120kwh in January.
hmm yeah that does seem super low. on a clear summer day we are exporting about 35kWh of that 40 or so per day. we didn't get ours hooked up proper til feb this year so i can't do a direct january comparison but our last billing period (14 oct - 13 nov) we exported 735.88kWh total. so yeah if i were you i'd be seeing what i could get out of that LCD to work out where the discrepancy is.
thanks and yup will do!
just learnt it's good to get solar inspected and serviced every couple of years. not sure what maint prev owner did. thinking ill get it done asap before peak summer.
c-tho: That's very good! What State/area are you getting this output?
suburban brisbane. so, y'know, the flipside is our fairly brutal brisbane summers.
I don't think this data will help you because you haven't considered:
1 - different number of solar panels
2 - different types of energy converters
3 - different positions/angles of solar panels
4 - different areas in VIC will receive different amounts of sunlight
5 - different rates that energy companies offer
Have a look at https://pvoutput.org/ and find a system near your location.
My last bill is -$38 with a 10kw system. Average over a year is 37kw per year.
December last year our 6.5kw system averaged 36.5kwh per day and in June 11.5 (because we have shading and a NE and SW split system. All up we pay around $300 for electricity annually for 6,925khw of used electricity. What a brilliant investment of $7,400 for our system. Imagine if we had no winter shading. Before this system our annual electricity bill was around $1700 (we have solar hot water too).
I have a question tho. If checking the app, my 6.6kw panel generates maximum 5kw. I thought it should reach 6.6kw.
How large is your inverter?
Ie. you may have 6.6kw of panels but if your inverter is only 5kw then your maximum solar generation will be 5kw.
Ohh cool thanks. You are right. The inverter is 5kw. Is this normal? Or the retailer did this on purpose..
Your seller probably explained to you the reasons/benefits of oversizing your solar system at time of purchase. They didn't try to con you….
https://www.solarquotes.com.au/blog/oversizing-solar-arrays/…
If your inverter was the same size as your solar system, you would find that it won't reach 6.6kw for longer than an hour or so when sun is directly above in summer, and certainly peak at much much less in winter
@avoidfullprice: Cool thanks for explaining. This is the answer I am looking for.
I actually asked my retailer this question a couple of times, they never answered this way… They just told me there is nothing wrong according to the app.
ATM with full sunny day 37kwh, Nth Coast NSW 5.4kw panels and 5 kw Fronius inverter.
VIC
6.6kW system with a 5kW inverter + 6kW battery
Nov 20 = 882kW total generation, so…
Average generation of ~28kW
(best feed-in ~30kW and daily usage ~10kW)
I can only get a 4kw system :( Unless I start putting panels on south facing side ^__^"
I just got a 10kw inverter installed (3 phase power) + 13.2kw panels. However they installed a 15kw inverter as the 10kw was out of stock (no extra cost which was good for me).
I am generating between 70 and 90kwh per day.
Got solar installed last Thursday - 8.5kW system and 10kW inverter (8kW inverter was out of stock, upgraded to 10kW for free). Max peak power so far has been ~7.8kW, with total energy averaging ~60kWh on the three sunny days we've had so far. I'm in NSW.
The question is: installation cost, maintenance cost, parts replacement cost, length of life and how much you save at the end ?
Ah Perth - we get relatively cheap solar systems, but absolutely rubbish FiT rates.
Just got my solar installed. After much frustrating and delays, it is finally installed. Thank you to all. Already generated 3.5kwh in like 2 hours on a 6.6kw system.
6.6kw system 3.5kwh is a bit on the low side, you should be looking at 60-70% from the system. I say 8-10 is a more reasonable number.
I'm interested in getting solar installed, but I just moved in and don't even have my first electricity bill yet. Should I wait or start getting quotes now?
Can anyone recommend a good solar installer in Sydney?
I'm located in North Rocks NSW
Generally our a 6kW PV system generates around 24 kilowatt-hours of electricity a day.
100% recommend getting solar. I paid 6k for around 6kw system. Mine will have paid for itself in around 5years. It's a no brainer.
I went from paying $600 to $800 per quarter. I now pay between $300 to $400 per quarter.
Go through Solar Quotes to get 3 quotes.
You get the added bonus of doing something good for the environment.
