Highest output in 5 months (since early Oct). And was still getting a few watts until 6pm. Roll on the ramp up :)

Usually, the inverter can go slightly higher than it's rated capacity. Mine seem to comfortably do 6kw DC even though it is a 5kw inverter. I have blips where it goes 6.2kw, on the AC side of things it is clipped at 5.5kw

johndoe11 · 07-03-2023 8:07pm

24.2kw from 4.4kwp west facing (250deg) & 4kwp east (70deg) in the midlands. 45 deg pitch. Was still producing 2.2kw at half five.

Previous best since January install was 17kwp.

idc · 07-03-2023 8:32pm

19.1 kWh North Dublin from 4.65 kWp SE/SW split

AckwelFoley · 07-03-2023 8:57pm

21kw today from 6kw South facing in Midlands.

Best by a longshot since October.

We're back in business 😎

irishchris · 07-03-2023 10:02pm

Just over 42kwh generated today. Nice return considering lots of parts of day had some cloud rolling in

43.9 kWh from 22x400w south facing today (Kildare area, mostly sunny) , best day since install about 3 weeks ago 😁😁😁🌞😉!

Thats fantastic to hear. I never expected to be able to carry any of the excess DC load through the inverter for use on the AC side. I suppose in warmer weather this capacity might be reduced when inverter is operating under that sort of DC loading and working harder. Initially thought it might be a data reporting error or God forbid the inverter might be fried after observing an almost immediate drop in power from the 5400kW peak to 1000Kw. Must have just been a pesky cloud at exactly the worst time!

paulbok · 07-03-2023 10:54pm

28.3kWh today, from a 6.84kW array, South facing, Roscommon. Best day of the year but am way behind last March already. Just had a peak at last year's numbers and was regularly hitting 30kWh during March, it really was an exceptional month. Still, almost at the vernal equinox and that's when it really kicked on last year until the autumnal one.

Usage really high today for some reason, so doubtful I'll have a nett surplus tonight, but getting closer.

sligopaul · 08-03-2023 11:07am

31.8kwh from 6.67kwp SE in Sligo yesterday, today also looking promising

My second string which is north west is starting to open its eyes a little - hope in another few weeks will pick up more.. its 3kwp versus 4 on string 1 which is south east. (yesterdays production) 23.1kwh

SD_DRACULA · 08-03-2023 4:23pm

Guess met.ie prediction was spot on with 16kwh in the end for today.

100% charge batteries for tomorrow's 💩show though:

ionapaul · 08-03-2023 7:15pm

We got a 6.72kW system installed yesterday, Dublin 18 southeast-facing roof. Today's total generated was 12.85kWh, used 5.57kW and fed the rest back into the grid, ESB Networks have already confirmed the NC6 form submitted by our installers ahead of time has been accepted so I really hope SSE Airtricity will pay us for the excess from day 1!

graememk · 08-03-2023 7:20pm

Aaand 50.4kWh (17kwp) good bit of cloud at lunchtime.

Looks like we'll miss most of the bad weather tomorrow.

jkforde · 08-03-2023 8:35pm

anyone know how to extract only the GlobalRadiation values from met.ie open forecast data at e.g. http://metwdb-openaccess.ichec.ie/metno-wdb2ts/locationforecast?lat=53.1234;long=-9.1234;from=2023-03-09T07:00

I've no experience with APIs, I just want to bookmark the web query so that I can open it in the browser and just see the forecasted GlobalRadiation values in a list

Moreilly · 08-03-2023 9:40pm

18.9 kWh from 22x400w south facing today (Kildare area)

Granolite · 09-03-2023 12:25am

Been mostly glorious sunshine in Sligo today and managed a total of 24.2kWh for the day. Didnt see the same peak values as yesterday though as I think some high altutude cloud was filtering some of the sunshine a bit.

jkforde · 09-03-2023 12:11pm

what a difference a day makes.... barely replenishing the battery this morning, but at least the panels' efficiency is maxed 😁 (just hope the snow sloughs off fully at some stage)

sligopaul · 09-03-2023 12:43pm

@jkforde was about to say the same thing as nothing happening today , 27.9 kwh off 6.67 kwp in North Sligo for yesterday...

Any joy with this? I'd also like an easy way to extract the daily radiation values from the link into Excel. I don't have Home Assistant.

DC999 · 09-03-2023 1:29pm

https://www.boards.ie/discussion/comment/120331800#Comment_120331800

Bump, this is one I'm interested in too. I don't know how to create or run python scripts. @bullit_dodger you're doing this, afaik and you're battery then charges based on it and a rolling 10 day 'actual' output. Though also said you're a software dev so well about my level :)

Is there an idiots guide to being able to extract that into a readable form to see the radiation values by hour? That's enough for me. I'm grand with doing it manually if there's a way to take it from the website and plonk it into something. Am sure I'd be able to setup something to pull in a python script, if I had it

Requesting data from the API

Data requests to the API are made by a http request to the URL:

http://metwdb-openaccess.ichec.ie/metno-wdb2ts/locationforecast?lat=<LATITUDE>;long=<LONGITUDE>

<LATITUDE> and <LONGITUDE> are substituted with the coordinates of the requested location. This will return an xml output containing the forecast from the current time until the end of available forecast.

http://metwdb-openaccess.ichec.ie/metno-wdb2ts/locationforecast?lat=<LATITUDE>;long=<LONGITUDE>;from=2018-11-10T02:00;to=2018-11-12T12:00

will return a forecast between 02:00 on 10th Nov 2018 to 12:00 on 12th Nov 2018. Leaving out the ’to’ keyword will return a forecast from 02:00 on 10th Nov 2018 until the end of available forecast.

---------------------------

so can only request based on specific location and start and end date & times, not by specific parameter looks like

hmm, maybe we can suggest to the Open Data Officer in MÉ to allow this type of request? 🤔 opendata@met.ie

the_amazing_raisin · 09-03-2023 5:55pm

A fine Irish day today when you could stare at the sky and struggle to find the sun. Only way to tell it's daytime is from the clock 😂

Pretty measly 2.9kWh generated today from a 6kWp south facing array. Peak generation was around 500W 😭

I didn't even bother plugging the Zappi in, wasn't getting enough sun to get over 1.4kW

Tomorrow looking a bit better, less clouds forecast so hopefully will get through the laundry for free

Yep... a big drop from 23 the other day to 3.6 today... still though it was enough to cover house base load for most of the day... all the washing etc was done the other day

Granolite · 09-03-2023 6:53pm

yeah it was a bit of a come down from the highs of the last 2 days, just 3.2kWh. After catering for the baseload put 1kWh into Eddi and 1.5kwH went back to grid.

idc · 09-03-2023 7:23pm

2kWh from 4.65 kWp SE/SW North Dublin

ELM327 · 10-03-2023 10:06am

6kWh for yesterday compared to 20+ earlier in the week, mad.

Looks great today though despite the forecast.

Jackson22 · 10-03-2023 10:19am

Lots of sun this morning, panels covered in snow though!

harvindhillon · 10-03-2023 10:40am

Just 3.4kwh yesterday but looking really sunny today but like others production is slow due to panels covered in snow lol

Newcastle, Dublin 6Kw South Facing

harvindhillon · 10-03-2023 5:23pm

Blew past the forecasts for today, 19kwh thus far
