Solar panel production figures

HungryHippos · 2 Mar 2023 at 17:54

Depends which figure you believe.

My generation today or my generation today

These headline stats sometimes differ a bit, not really worked out why, usually they are very close (+- 0.2).

18.8 kWh here, surprisingly as it kept clouding over

Absolutely terrible weather today, but you can totally see the difference in light levels - even with heavy cloud/rain, I still managed 13kwh today.... Roll on summer!

SoliD · 2 Mar 2023 at 19:12

21 kwh In the end, generating through to 6pm.

gpuerrilla · 2 Mar 2023 at 19:20

4.9kWh. Very grim.

Ron-ski · 2 Mar 2023 at 19:37

15.85kWh from the SolarEdge system
7kWh from the east garage panels
5.53kWh from the west garage panels

Total: 28.38kWh
Tomorrows Prediction: 17.1kWh

Those of you automatically sending data to PV Output, what value do you send every 5 minutes, is it the days total generation in watt hours?

i'm sending, on fifteen minute intervals, v1, days total generation in watt hours, v2 present generating power in watts, v4 consumption in watts (doesn't seem to be working for me though), and v6, ac voltage. Voltage I'm sending because my house is near 250v. Transformer is around 40-50 meters away, so I may have to think about a voltage optimiser (my amplifier hums....).

@branddaly Thanks, I'm getting there, have actually managed to upload todays garage generation.

My Solis inverter and my givenergy give different figures as well.

This is both from the givenergy one alone though, same inverter even, it's weird!

Yeah mine is the same. And it actually adjusted down from 21.02 or something to 20.8kwh when I checked just now.

Oh wow! Yes it's a little bit frustrating isn't it? I mean my Solis inverter says it got 26 but my GE says 25.6. But pvout says 24.3!

Ah well don't really care it's a good day regardless. Looking grim for the next week with even a threat of snow!

@Ron-ski I see a new challenger has entered the ring

Ronski's Combined Systems 15.523kW

PVOutput.org - share, compare and monitor live solar photovoltaic output data

I've now got Node Red running on the Victron Cerbo GX and uploading data directly to PV Output, only issue is that I haven't worked out how to get the daily yield for the SolarEdge inverter, this value appears to be missing. So for now I have three systems on PV Output, the original SolarEdge system, the Victron system and the combined system which takes it's data from the other two and combines it.

All appears to be working as hoped,

HungryHippos · 3 Mar 2023 at 10:24

Having 3 systems at once is definitely one way to defeat Katie!

SoliD · 3 Mar 2023 at 10:42

on and off so far today, bit of cloud then the sun bursts through for 3.5kW upwards! But got through the night with the battery even with the car deciding it would charge for 2 hours last night and taking 3kwh off the grid annoyingly. Now to move to Octopus Flux!

Freefaller · 3 Mar 2023 at 11:22

Cold cloudy and miserable today.

Oh and the weather isn't great either.

branddaly · 3 Mar 2023 at 12:19

Another poor day, even worse when compared to the rather poor forecast. Just thick, low clouds everywhere.

Ron-ski · 3 Mar 2023 at 13:16

Not quite as good as yesterday, but up 14kWh, and battery which also made it through the night is up to 85%.

Super dull and chuffing chilly as I found out on a bike ride with the wee man! My fingers are still numb!

Forecast is indeed dire, looks like first half of March at least will be very uninspiring!

Does warm the cockles at times like this to have the decent sized packs and still be able to keep costs minimal. Just ignore how much they cost in the first place for maximum happiness.
