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As was my decision to upgrade my system from an outdated installation to a new more efficient system

    • Welcome Bazzle - enjoy your stay and I look forward to reading your contributions.
    • We have had our 3.4kw system ever since solar was introduced commercially here in Vic. Ours was installed  back in Jan 2009. We have 2 strings of 10 x 174w Solartech and Topray panels running into 2 x CMS2000 invertors giving a max of 3.4kw normally. Had no real issues with the set ups at all. I do have a spare CMS2000 but not needed it yet. Both invertors have an small aux fan under the heatsink that comes on when inv reaches 40c powered by a 12v panel.
    • I have the 5kw Sungrow inverter and have no problems at all so far  I have also learned recently that if you add a seperate ( I think it’s called ) a Sungrow S100 Energy meter. With this extra meter you can also see via the app the export to the grid amount and many other features over the standard dongle  Without the meter you only see your input from the panels to the inverter     
    • Have narrowed my search for a solar system down to 2 suppliers, who would you run with? 13.2kW System Option 1 REC panels Sungrow inverter Master installer certified $10990 Option 2 Canadian Panels Fronius Inverter Uses local, well reviewed installer $9680 Both are semi-local companies who have been to site to evaluate the install and spent time determining my needs. The REC panels from option 1 have a longer warranty (25 vs 12) and the fronius inverter from option 2 has a 13 year warranty vs 10 for the Sungrow.  Option 1 comes with Solar analytics, a 3rd party software and app that is apparently worth $5-800. All other criteria are essential the same So I guess it comes down to how much value I put on the panel vs inverter quality and whether the 'master installer' certification is worth another $1000. Keen to hear your thoughts   **Edit. Option 1 reduced their price and I have decided to go with them
