  1. It would be a newer, more modern meter that would be installed. When I had our system installed, before it was allowed to be turned on I had to have a new meter put in. The old one was a digital Time-of-use one. Origin put the new one in, at a cost of $45. The new one is read remotely online, no need for a meter reader to come around. On the Origin website, with the new smart meters you can see your daily usage, and your daily feed-in. They’re well worth having, especially at the very low cost that Origin charges for the installation.
  2. Analysis for the full year of 2020 Total Production: 12.882 MWh Total Consumption: 12.931 MWh Highest Production Day: 59.3 kWh on 11th November Lowest Production Day: 1.9 kWh on 26th July Daily Averages - Production: 35.2 kWh Consumption: 35.3 kWh Own Consumption: 16.6 kWh Export: 18.6 kWh Import: 18.7 kWh Cost: $1.88 Yield: 4.1 kWh/kW
  3. Analysis for December 2020 Daily Averages - Production: 36.0 kWh Consumption: 34.7 kWh Own Consumption: 18.0 kWh Export: 18.0 kWh Import: 16.7 kWh Cost: $1.71 Yield: 4.2 kWh/kW December was a pretty cruddy month weather-wise, with only 90% of predicted production, 1,115 kWh against a predicted 1241 kWh. The best day was December 7th with 58.3 kWh produced. The worst day was December 19th with just 11.1 kWh produced.

Analysis for November 2020 Daily Averages - Production: 44.5 kWh Consumption: 37.6 kWh Own Consumption: 20.6 kWh Export: 23.9 kWh Import: 17.0 kWh Cost: $0.23 Yield: 5.2 kWh/kW November was 13% better than predicted, with production of 1,336 kWh against a predicted 1187 kWh. The best day was November 11th with 59.3 kWh produced, our second best day since install. The worst day was November 5th with just 6.7 kWh produced. In November we
  5. We have just passed our first year since our system was hooked up. The vital stats are: Total Solar Production: 12.96 MWh Total Household Consumption: 12.66 MWh Energy Exported to Grid: 6.96 MWh Energy Imported from Grid: 6.66 MWh Total value of power produced: $2,766 Highest 5-minute output: 8.35 kW (14 October) Highest daily production: 60.604 kWh (28 December) Highest daily consumption: 90.427 kWh (28 November, the last day of the first year, which was a stinking hot day, and the longest we've ever run the air-con) Highest daily exp
  6. @manchu I'd suspect WiFi connection reliability. I never count on wifi, and always run a cable if possible. My Fronius is hard wired, and I never have issues (unless I'm fiddling, which I'm prone to). Another thing to make sure of is that Night Mode is set to 'ON' in your inverter. If you have a Fronius Smart Meter, you MUST have night mode enabled so your logging works correctly. I've made a little video for you here on how to do it. Cheers, Jason.
  7. Good on you Manchu. How many kW of panels did you end up going with? The Fronius Primo inverters are good, I have the 8.2kW like you, with 8.58kW of panels. Has the installer set it up for 5kW export limit? Luckily here we don’t have to do that, so with the weather lately I’ve been exporting over 7kW peak to the grid most days, with some over 8kW. That Origin plan looks pretty good. A 15c FIT is about the best you can get at the moment, I think you’ do well. Cheers, Jason.
  8. Well my first year is almost up, and Origin have decided that my 21c feed-in tarrif won't continue. They don't appear to offer any more than 12c to anyone any more. I've run my spreadsheet over all the offers I can find, and staying with Origin seems to be my best option. My new electricity rates will be as follows: 55c/kWh Peak 25c/kWh Shoulder 15c/kWh Off-peak The new contract with Origin will give me a 16c/kWh feed-in tarrif. So now I know that my cheapest power is 15c/kWh, which is during the Off-Peak period. Power from my own solar producti
  9. I agree with everything you say @Tezza, however if you want solid figures, you have to use guaranteed quantities, which is why I used the warranted throughput. 70Mwh is a bit of a stretch, pretty much double the warranted throughput. If it has degraded to 80% after ten years (and 37Mwh throughput), it would take something like thirty years to reach 70Mwh, by which time something else will have blown up long ago. I suspect the break-even point is somewhere between, like 15-20 years, in a full charge-discharge cycle per day installation, which is probably about the same time the
  10. Analysis for October 2020 Daily Averages - Production: 39.1 kWh Consumption: 33.6 kWh Own Consumption: 17.6 kWh Export: 21.5 kWh Import: 16.0 kWh Cost: - $0.21 (ie. earned $0.21 per day) Yield: 4.6 kWh/kW October was almost exactly as predicted, with production of 1,211 kWh against a predicted 1223 kWh. The best day was October 21st with 57.7 kWh produced, our third best day since install. The worst day was October 25th with just 7.2 kWh produced. In October we had 20 'Green Da
  11. A fairly simple way of gauging relative performance, day to day, or site to site etc, is kWh/kW. Simply divide the kWh produced by the kW of panels installed. So in your case of your average production, 28 / 6.6 = 4.24 kWh/kW over the period. Cheers, Jason.
  12. An excellent result. Not sure about Brissy, but August and September were very good months for solar in Sydney. Cheers, Jason.
  13. Analysis for September 2020 Daily Averages - Production: 40.6 kWh Consumption: 30.3 kWh Own Consumption: 15.8 kWh Export: 24.7 kWh Import: 14.4 kWh Cost: - $1.29 (ie. earned $1.29 per day) Yield: 4.7 kWh/kW September was sunnier than predicted, as production was 1,218 kWh against a predicted 1093 kWh (11% over predicted). The best day was September 26th with 56.9 kWh produced. The worst day was September 18th with just 6.0 kWh produced. In September we had 25 'Green Days', where we exported more than we imported, our b
  14. Hi Arnold, welcome to the forums. With your Fronius Smart Meter, yes you need a ‘Premium’ account, but you just have to create it, it costs nothing. It’s free. Making a premium account gives you a lot of very useful extra features. Cheers, Jason.
