We moved into our current house at the end of June. This is the first time we've rented a house with solar so we don't know anything about them, we don't even know if they're working properly or not.
When we look at something like the switchboard in our house, it looks like the solar panels are working.
But we don't know if it's true.
1. How can we know if the solar panels are working?
2. And can you see how much the solar panels contribute to the reduction of electricity costs?
I logged into the AGL website and checked it thoroughly, but I couldn't find it.
I downloaded the AGL mobile app and checked it thoroughly, but I couldn't find it.
Ive had a similar question. Ive spoken to many AGL personal and still i dont have any solar activity on my account. AGL are still charging me for electricity even though i have solar. Its an AGL issue.
ive also paid my Last account and they say I haven’t. AGL app doesn’t show up to date payments.
ive asked questions via the help link and they say they will respond in 30 minutes.
no im not happy with AGL. I haven’t been for some time. A change is inevitable.
I suggest you contact your rental agency.
On your switchboard it will tell you the location of your inverter.
If you cannot see any activity on the inverter then it may be switched off or isolated at your switchboard (meter box).
Again you should contact the rental agency, if you do not understand how it works you may cause damage to the inverter will will be chargeable against you.
Thanks for addressing this topic. I was looking for the information regarding the same Keep sharing the info, kudos.
New inverters seem to run seamlessly and will auto restart once power is replied.
Older inverters often have to be manually restarted.
Lets see what we can do about explaining how your solar system works.
When the sun illuminates the solar panels they start converting solar into Direct Current.
The panels are generally connected in SERIES which mean that the voltage output is multiplied by the number of panels but the current is limited to the maximum output of one panel.
(For instance I have two sets of 12 panels rated at 31.8 volts and 8.74 amps per panel)
Therefore each set of panels can develop (12*31.8 volts at 8.74 amps) 382 volts (DC) at 8.74 amps.
This equates to 3335 watts *2 or a 6.6Kw system.
You must be aware that this can only occur under PERFECT CONDITIONS.
YOUR HOME USAGE
You must understand that your residence will use your solar power rather than take power from the grid.
If your usage exceeds the amount of power you are generating then you will have no output to the grid and still consume power.
Say for instance it is a hot day and you have your RC air-conditioner on and it consumes 3000 watts (3kW) or more and your solar system is producing 2kw then you will pay for 1kW of usage.
The smaller systems installed in many houses only produce 1 to 3kw on a good day.
You also must remember that usage is instantaneous, so an AC unit when the compressor is running consumes 3kw (or more), but when the compressor is not running you still consume power with the fans etc which may be a high at 0.5kW.
So on a day when you are running your stove, washing machine and AC all at the same time you will not produce any power but will have reduced your electricity usage from the grid.
When using your AC (Heating or Cooling) run it at a temperature that is comfortable.
For instance in spring if its 26 outside would you come inside and cool the house down to 20.
So now this is where the inverter comes in.
The purpose of the inverter is to convert the supplied Direct Current from the Solar Array(s) into approximately 240 volts Alternating Current (the Australian standard).
Now the inverter serves four purposes.
The inverter can also have other options such as wireless and the ability to update a web site.
Inverters normally have a minimum of an indicator light and a small display.
Of course the above is for a basic system as you may have an attached battery system which is also supplied by the inverter.
The reason that the inverter limits the amount of current to the grid is so that you meet the requirement of your installation to output the maximum allowed under your Generation Licence.
The reason you can have panels that can generate more than your allowance is because when you have overcast days you can still generate up to your Licence limit and maximize your income
READING YOUR METER
The easiest way to check if you are generating power is to find out how to read your power meter. (Information to do this is freely available on the web).
The second method is to look at your AGL Web Page or App and see if you are producing Solar every Day.
Be aware though that AGL does not show you your current activity and may be showing current data as for THREE days ago.
If you have two meters and an older solar system you may have had a second meter installed to read your solar output.
If you have a single meter you may be able to work out your meters by simply reading them by pressing through the button and ignoring any obvious readings (ie dates and times).
When reading your meters you will normally have up to three readings.
Peak meter is your main usage and this will be changing constantly.
Off peak or controlled load only normally operates after 11:00pm (23:00) and before 6:00am (06:00)
Solar only operates when there is sufficient sunlight.
Write down your readings after sunset (ie in the dark and before 23:00) ignoring obvious dates / times.
Note the reading and the meter number for each reading.
You might end up with:
Where 0X is the meter number and xxxx.x is the current meter reading
This is from my meter and we do not have any Off Peak connected.
So if I go back one hour later and read I might get.
Only 04 has changed which is what I expect as I am only using peak at this time.
If you have off peak connected then you will have to work out what of the two meters is Off Peak and what is Solar.
This is simple before the Sun rises you need to re-read your meters.
You know what is your Peak (04 in my case), so besides that only one meter must have changed, this must be your Off Peak, note that and the remaining meter is your Solar.
So after the sun has risen read your meter to confirm that your are generating solar. If you are not home during the daylight hours you can simply read the Solar meter that night and you will see how much you have generated.
SEEING IF ITS WORKING
Now to check if your inverter is working.
Depending on the location of the inverter you may have one or more AC isolating switches.
Isolation switches can also be a physical switch or a circuit breaker in your meter box.
Then next to the inverter there may be one or more DC Isolator switches.
You can only do this when the sun is out and the panels are generating power.
If you have any issues contact an Electrician or if in a rental, the Agent or Owner.
All of the above is just a guide to assist users.
