Your first billing period after Solar Installation


Recommended Posts

Well the first 3 months went quick 

Regular monitoring gave me a good indication of how much power I’m generating 

Just a refresh I have a 6.6 kWh system x 5 Kw inverter x 20 Panels 

Highest daily generation was 39.8 kWh ( and it’s not summer yet ) with an average of approx 28 kWh 

I just received my first bill and I’m happy to report that it’s in credit 

Drum roll 

Credit $424.39 

 

At this rate I will pay off the system in no time 

System cost was $3500

An excellent result.

 

Not sure about Brissy, but August and September were very good months for solar in Sydney.

 

Cheers,

Jason.

 


We had a few rain / cloudy periods in Brisbane during the first billing period 

Even then the system was generating close to 20 kWh or above if a little sun came for short periods

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.

I'm still waiting for the end of my first billing period,  but it's looking pretty good going by the Fronius data.  

8.2kW inv, (limited to 5kW export).   Since 18/11:

  • PV production = 2,440 kWh  (~39 kWh/d average ,     ~65 kWh/d peak)
  • Self consumption = 526 kWh
  • Total consumption = 981 kWh.

Going by those numbers it means that your decision to install a solar system was justified 

As was my decision to upgrade my system from an outdated installation to a new more efficient system

    • With a name like Full Range, I expect nothing less! 🙂 Thanks again for the reply. No Gas here and electric HWS. Average 22 kW per day. I have so many aspects to my Stereo and would love to know what it all uses. Lots on small power supplies running different items. I could try and put it all on one plug and use one of those little meters. In the past year have replaced a few things. Got a new fridge 520L kitchen, New F&P Front loader washing machine, New 65" TV's and threw out my 2nd 20yr old fridge I had in back garage all in the hope of lowering my Energy bills. Replaced all lights with LED's. Still after all this my bills are high for me at the average 22kW/day. Looking forward to Solar ASAP. 🙂  
    • My average use going by my past power bills is 14 kw per day  I don’t have advanced power monitoring but can inform you that my power bills have been reduced by 2 thirds  I mainly work nights so I consume most of the energy during the day  Energy use breakdown  Aircon system , 25 yo refrigerator , large 70” TV , washing machine, dishwasher, spa pool heating, and a huge stereo @Marc knows about my HiFi system    Please note that I have solar hot water and gas for cooking hence my lower daily power use   
    • Just a couple of questions to the ones who have the great monitoring. How many units does one typically feed back into the grid in a day? Also what does it take to max out Solar? Like could I use my Stereo, 2x Split Air Con. Then expect I could still use the dishwasher and Washing machine. Plus start vacuuming and also put the kettle on of course. 🙂 Just trying to gauge what system I can take advantage of in kW. 6.6kW or 10kW and what to expect in managing my usage. Like is the vacuum cleaner or the kettle already say using 20% each of your generated solar energy. Washing machine 10% etc Just a rough guide if possible? Would like to not be using power from the grid as much as possible in those daylight hours but don't want to over capitalize if there's no point.
    • These are the 330W panels that were recommended for me so you can compare the specs  https://www.trunsunsolar.com/wp-content/uploads/download/au/EN-DUDRIVE-TSHM-120L-AU.pdf   And this is the inverter  Sungrow is the worlds number one inverter manufacturer  https://service.sungrowpower.com.au/files/Web_Files/FAQ/Crystal/Troubleshooting/UM_201803_Crystal G2_SG3K_5K-D Datasheet_V1.0.pdf
    • Yes with only 3c feed in tariff, it got me thinking of 8kW Inverter and 10kW panels. So I could use a lot more items in the day hours instead of watching everything I use. I take it both sides with the panels wont always see the sun together. Mornings will be at most 5kW and late afternoons 5kW. 10kw in mid day times. The lay out from the last quote with them on the metal roof. Just sent a new quote to me with 24x 440w JINKO Tiger-pro Mono Facial TR technology + Half Cell Total is $7500. I did not ask for these panels but I think he thought they might be worth going to as there will be less of them. Maybe could reduce the price considerably with cheaper panels? Any good cheaper ones or is it worth spending the extra on good panels?   Not sure which Inverter to go for but he suggested Fonius or SMA.
