Daily Solar Generation - My 6.4 kW Solar Produced 41.7 kW 11/11/2020

Hi everyone, greetings from Girraween NSW.

I have recently installed solar, Jinko 400W x 16 panels and Goodwe 5KW inverter and very happy of the outcome. Mine is north facing roof.

It is producing over 40KW on a sunny day and 30 on a cloudy day, It is look more than the average.

Please share your experiences and thoughts


  • Rule of thumb is a kilowatt of panels produces a bit above 4kWh per day, averaged over the year.
    So 40kWh is great.

  • I have a similarly sized system (6.7 KW panels, 5KW inverter; different brands) nearly half facing North, the rest West-facing, which saw just shy of 41KWh yesterday. It's the first 40+ day I've seen in a while, and saw peak production (clipping) from 11am to 3pm. I'd say pure-North with no shading sees you inline with what I'd expect (I lose a little with most of my panels being West-facing).Good days, nice to see getting more back from the electricity provider than we pay.
    In Sydney also.

  • Great outcome, happy for you! Can you share who did you go with and how much did it cost if you don't mind, please? Thanks in advance

      Installed SUNMAX SOLAR and cost $2249 after bargain with few friends together , I think It is the best price

      • What brand/model and capacity panels? What capacity inverter?

        • Jinko cheetah 400W panel x16 ( 12 years product and up to 25 years performance warranty and GOODWE 5KW inverter ( 10 year warranty)

          • @TAN: That's an amazing price for good entry level components.

            Do you feel the installation was of a high quality?

  • I generally get 40ish on a decent day. A few days ago got 49. 5kw inverter 6.6 of panels.

  • similar sized system. jinko plus Zever. 12 east, 8 west.

    34.6kw yesterday - Crows Nest That's about as good as it gets here.

  • I got 30kW yesterday in Parramatta. 5.2kW LG panels and SolarEdge inverter. 9 panels north facing and 7 west. That reminds me I need to get up and give them a clean one day…

    • Which company are you with. I recall reading about some companies won't give you a feed in deal if you have more than 5? or 15kw panels

      • Sorry let me clarify. 30kWh from my total of 5.2kW LG panels. Ie. A pretty standard sized system (albeit 6.6kW of panels feeding a 5kW inverter is the most typical).

  • Lots of factors.

    You are in Sydney.

    For someone in QLD you are lower than them. For VIC you are higher than us.

  • In Perth - no probs getting over 40 on a good day.
    Got about 8 panels facing NE, and 10 facing NW

  • That’s an excellent result. I find usually when it gets very hot but sunny it’s not as effective as just warm and sunny. Heat kills power generation

  • 35kw, although with locked in 23c FIT vs current 12c for recently installed panels, thats almost 70kw value

  • QLD - 8.5kW panels (11 east, 12 west) - averaging about 50kW a day if there's no clouds on a nice sunny day between 27 and 32 degrees

    I export my numbers to http://pvourput.org, and check out my neighbours generation.

    I have a west facing 3.52kw system in Canberra, generated average of 4.414kWh/kW last year and 6.162kWh/kW last November

  • Got 43.7kwh on my 6.6kw system on Tuesday

  • id be more interested in what people are averaging daily calculated on a whole year as solar performance fluctuates throughout the seasons.
    I have a Fronius / JA 6.6kw North facing system in Sydney yielding 28kw a day.

  • Best day this week for me was 23.85kWh from 2x2kw systems. Average over the last 6 years is 15kWh per day.

  • Hi TAN,

    Can I please ask you who was your installer, do you have their website/contact details? How was your experience with them? Price seems really good to me for your panels and inverters.


  • 41kwh a day is nice, but best is trying to beat that 7kwh/kw. Last year on solar solstice Melbourne got a perfect day and pretty much every system hit its max.
