Solar panel production figures

We've still got a 40 foot fridge trailer at work

Full day of sun forecast for tomorrow

35.84kwh and think that's them for the day!

Very nice, what is it with PV Output under reporting though? It does that with my SolarEdge system as well, but the Victron one is spot on, weird.

Anyway 11.29kWh today, much better than the last few days. Tomorrow was forecast to rain, then it was sunny all day, and now it sunny intervals which of course is better than rain.

Tomorrows prediction is 16.4kWh, hopefully it will be better than that.

Ron-ski · 11 Mar 2023 at 09:48

Currently at 3.6kWh, not blue skies but it's bright and the sun is shining.

Ron-ski · 11 Mar 2023 at 10:13

My solar forecast is predicting 8.5 for today, I'm already at 5kWh.

Ron-ski · 11 Mar 2023 at 18:47

26.6kWh today, and battery full as well, Katie still got first place with ~~a fair bit more than that~~ only slightly more than that.

@katie279 Did you work out what your data error was caused by, as your PV Output is correct today?

Efficiency Ron! All about Efficiency.

Not any more

The efficiency award goes to @Oldman2 with an efficiency of 4.415kWh/kW which is impressive considering we still had some cloud.

I'm never going to win efficiency awards now, the garage system was always a compromise, and as such lowers my overall efficiency - if my system had been as efficient as Oldman2's then I would have generated 38.5kWh today. My system is three times bigger than his, but I only produced twice as much, and we're not that far apart geographically.

Efficiency:

SolarEdge 3.4
Victron 2.73
Combined 3.04

Yeah, I hear old men talk more about their efficiency more....

Old men are usually wise men

15kWh so far today, battery at 92%, will I get a Pylon on my IHD???

Ron-ski · 12 Mar 2023 at 13:15

I'll find out soon, battery now at 98%, then two hours of absorption (constant voltage), so export will ramp up if the sun stays shinning.

Ron-ski · 12 Mar 2023 at 18:36

21.23 Kwh , clouded over mid afternoon, but battery full again.

Ron-ski · 12 Mar 2023 at 18:40

No I didn't, but my export is not fully set up yet, and the electricity meter is only showing the one TOU tariff, so that hasn't updated yet either.

Ron-ski · 12 Mar 2023 at 18:51

I might change mine, get the Hilderbrand one which works directly with the Biright App, then it can be integrated with HA once I get that working.

Ron-ski · 13 Mar 2023 at 13:25

Currently up to 17kWh, makes a pleasant change after last week.

cant see me reaching target this month, its been dire so far. But we may get a good day tomorrow....... im starting a twitter trend below lol

#ronskistolemysun

Well it's either me or @katie279 but looking on PV Output she's clearly having a bad day.

PS 23kWh

Ron-ski · 13 Mar 2023 at 19:08

Just a mere 24.25kWh, and to think I charged the battery to 60% this morning - 8.1kWh exported. Still a rather cloudy day though.

Ron-ski · 14 Mar 2023 at 10:18

Yes, I felt sorry hogging the sun, currently raining here but will hopefully clear up by early afternoon.

@Welshman someone on another forum said they phoned Octopus and they sorted out the export. If I get chance today I'll try and phone them.

mine is done ron.....i posted in the flux thread

Didn't see that until after I posted here.

Ron-ski · 14 Mar 2023 at 19:13

Lousy morning but the sun came out this afternoon after I stole @Welshman sun, ended up with 18.06kWh.

Tomorrows and Thursday's forecast looking good

Ron-ski · 15 Mar 2023 at 08:03

8am and we have 1.7kW of production, given the forecast I didn't charge the battery either.

Ron-ski · 15 Mar 2023 at 08:13

@Welshman Nope it was 1.7kW, although perhaps I should have said generation, as in the actual power the panels were producing at that moment in time. Look on the VRM dashboard, where it says Total Solar, directly underneath it shows the current power in Watts.

Damn. Where are you guys looking at forecasts. Met Office have been completely wrong two days in a row now.

I was expecting it to be cloudy today so half charged the battery overnight.

Come on, your only 8 miles away from me, the BBC weather forecast has sunshine all day, maybe clouding over a bit in the afternoon.

It is odd how the met office and BBC varies so much though.
