Aha,
Got a keyboard in front of me for the first time in a week, flippin hard word typing on a Samsung S3 mini....now, who's turned off the sun, seriously unimpressed I've escaped from hospital for a few days to overcast skies

Still, according to my solaredge dashboard I only need another 24kWh to make Aprils PVGIS

3 consecutive maidens. Beat that Jimmy Anderson.

Need to check but I've certainly averaged more than 5 O's over the past couple of weeks and have had a couple of 7 O days.

The elusive 8 O's is still out there I think. Record was 7.6 last summer.

My first full year completed at the end of March with a very healthy 4,467Kwh or 1.12Kwh per Kw. That beat my expectations of 4,100Kwh.

Expect some miserable figures from Lincolnshire today.:(

12.00 & the panels finally wake up!

Well, today is looking "ok" again - not as good as late, but I reckon 40 winks maybe?

Fri, Sat = Grim

Sun = Very grim & very wet!

Mon, Tue, Wed = Reasonable for a Typhoo or so.

That's my guesses.

Hi

Probably something like this then (WSM, 4kWp array on a South facing 35Degree roof) .... ( https://www.meteoblue.com/en/apps/pointsolar/calculate/?loctype=latlon&lat=51.346&lon=-2.977&kwp=4.000&fangle=180&sangle=35&bt=Submit )

&loctype=latlon&lat=51.346&lon=-2.977&kwp=4.000&fangle=180&sangle=35&bt=Submit

&loctype=latlon&lat=51.346&lon=-2.977&kwp=4.000&fangle=180&sangle=35&bt=Submit

.... Note, the representation above changes as the forecast and date changes ... so it might look different when you get to see it! ...

That looks great and is gimmicky, but not at all accurate - even for today. Virtually no production here until 11am, then choppy as anything, before clearing after mid-day - it missed that!

Might just scrape a Hawaii tonight, meaning 12 of the 23 days of April so far will have been Hawaiis! Awesome weather we're having for this time of year!

Hi

... it's probably just as accurate as the forecast which sparked the 'grim' outlook, especially so considering it's simply using weather forecast data and presenting it in a different format ....

Might be a bit 'gimmicky', but I find that it's much easier to read than the standard row of hourly boxes with different colour suns (some with rays, some not) and an array of various cloud types and sizes, temperatures, windspeed, UV intensity etc ... it's there as a simple line which processes all of this for me and gives an idea of what the generation distribution curves for the next few days are likely to look like ...

Having said that, we mainly use MkI eyeball combined with a look at Sat24 time-slice photography if short-term accuracy is required .... it reflects what's actually happening now as opposed to the forecast obtained from crunching data through a weather model overnight ....

Well let's do a drains up after tomorrow. The first "grim" forecast.

I'm only saying it missed the mark today. The weather app I use showed a reduced number of Sun hours today, hence my comments last night. Having said that, I'm not too short of a Hawaii at the moment, so it's all relative - we've been spoilt this month!
