Answers on moving house, getting connected or using your electricity and gas meters
Hi everyone,
I just wonder if anyone could give me some helps/advices on this? My smart meter says at 1pm, I have exported over 4kw of solar power to grid but AGL app says less than half (1.91kw) were. My smart meter also showed at that time I used only 300W at that also. I’m not sure what went wrong
You are getting confused over what meter you are reading.
A SOLAR INVERTER shows the total amount amount of power that your solar panels are generating.
The SMART METER is connected via your switchboard to the Electricity Grid.
Your retailer (AGL) has access to your meter readings.
The Smart Meter can only read INPUT from the GRID or EXPORT to the grid.
If you look at a particular time via your APPS then your EXPORT to the grid is the power generated by Solar MINUS the power consumed by your house.
Your meter can only do two things (for a single phase supply) and that is either give an export figure or an import figure.
You get charged for IMPORT and get paid for EXPORT.
Here is some figures from my system for the last week.
Date | Peak | Exported | Solar Gen | Used | Meter | Solar |
15/09/2021 | 2.942 | 28.206 | 32.1 | 3.894 | 4845.029 | 18882.63 |
16/09/2021 | 3.425 | 31.342 | 34.9 | 3.558 | 4848.454 | 18913.97 |
17/09/2021 | 4.513 | 28.209 | 33.2 | 4.991 | 4852.967 | 18942.18 |
18/09/2021 | 5.759 | 20.577 | 25.2 | 4.623 | 4858.726 | 18962.75 |
19/09/2021 | 3.917 | 27.604 | 33.9 | 6.296 | 4862.643 | 18990.36 |
20/09/2021 | 4.401 | 19.691 | 24.4 | 4.709 | 4867.044 | 19010.05 |
21/09/2021 | 3.403 | 19.162 | 24.1 | 4.938 | 4870.447 | 19029.21 |
So for yesterday:
I will get charged for 3.403 kWh.
Will get paid for 19.162 kWh.
Self consumed 4.938 kWh of my generated power.
You can also see that I know my meter readings for Midnight on that date,
I have a heat pump hot-water system that consumes about 3 kWh of my Solar (thus my hot-water is free).
Below is part of my data for yesterday 21st Sept
Date | 15:00 | 15:30 | 16:00 | 16:30 | 17:00 | 17:30 | 18:00 | |
Imported | 20210921 | 0 | 0 | 0 | 0 | 0 | 0 | 0.017 |
Exported | 20210921 | 0.72 | 0.792 | 0.418 | 0.459 | 0.517 | 0.526 | 0.138 |
I actually did not pay for any usage from 7:30am till 5:30pm and you can see at 6pm I paid for .017kWh and also got paid for .138kWh.
Now for my current billing period :
Cost Per Day | -$ 0.7225 | |
Supply Cost per Day | $ 0.8910 | |
Peak Usage per Day | $ 1.7597 | |
Off Peak usage per Day | $ - | |
Solar income per day | $ 3.3732 |
Basically though unless you have the ability to create your data into one reliable source you should just rely on the AGL to show you your usage via the app.
Cheers
Neil
