Nice, SE SW split gives a nice range from morning to evening.
Generally that kind of expansion is not worth it for winter consumption in isolation. Couple of panels optimised for south with a nice angle, yeah - but 8Kwp is a lot. You would be exporting A TON in summer. Granted with FIT that's not a huge concern anymore, but you'd most likely be in taxable space with 10-11 kwp of panels. Also, whats your inverter. 5kw? Or would you be going with a seperate inverter?
I'm not saying it's a bad idea, just making sure your aware of the downside. If I had my way, I'd have 20-30Kwp in panels , but not likely to happen in a semi detached in south Dublin.
Have you had yours in summer yet?
7.59kWh today....3 good days in a row, hopefully few more good days to come!!
I DIY'ed phase 1. So I could get the grant for Phase 2 I suppose. It would down to pricing at the time. It's only an embryo of an idea at the moment though. Other projects being planned as well elsewhere.
I have a 6kW inverter so I'd need to add a 5kw inverter. Export limiter 6kW ( I'm sure ESBN smart meters will be detecting anybody who exceeds limit)
I'm think I'd be getting huge FIT in the shoulder season, April, May, Sept. Oct etc.
And on wet summer days it would still be picking it out.
You could also fill an EV during the day in summer, as you would have potentially 11kW from PV and 6 from batteries.
Lots of possibilities with it really.
Great day of generation for January 🌞
19.5kwh from 6.9 kWp South facing today. Nice.
Great yield, that's a good day in the summer for me. Is that with the Sunsynk 5KW inverter?
25.1 in January 😍
Would you need to go down the nc7 route if going for the grant?
6kw sofar hyd hybrid and 2.5kwp goodwe standard inverter
It's a killer for me too. I have a lovely production curve going until about 12pm and then it falls off a cliff as the sun disappears behind trees.
I guess not as it would be irrelevant to the installer what's already there.
I don't know though.
And I'd be capped at 6kW export anyway.
Last 3 days have been good, 8.4Kwp S facing array.
4th 22Kwh produced, 15.4kwh exported.
5th 21.7Kwh produced, 6.2Kwh exported.
6th 24.2Kwh produced, 12.8 Kwh exported.
A quarter of Decembers production in 3 days.
Oh to have a south facing aspect in winter!
I got about 6 on a low slope, 8.6kWp NE/SW yesterday. Although it was much more cloudy up here too.
Like mine? 😜
I remember my 1st winter thinking my install was wonky as my E/W output dropped off a cliff from late Sept :)
Yeah, spare a thought for us E/W peeps.
People banging out double digits and I'm scraping 3Kwh off 6.5Kwp - LOL. Still come summer, I'll be producing 1kw at 6:30am :-)
23.8Kwh today from 8.3kw array south facing
20.6 kWh on my 6.1kWp system south facing, south of Cork City
Had 20 kWh also yesterday and the week ahead is looking fantastic as well 👌, that power curve is a thing of beauty. Bit of mist alright in the morning but nothing major
Fog never lifted here all day but still managed 3.5.
Record for me for January. Came in above forecast at 26.4 kwh today.
9.6KW today on a 4.3kw array SW
3.38kW...freezing fog all day, never lifted...was pleasantly surprised to even get that today
11kw today. 4.3 kw system south facing . North Leitrim
I’ve East panels on a flat single-storey roof and the main roof. You can see when the sun rises enough to hit the flat single-storey roof panels, around 10am now (in yellow below). Then the output ramps - well, ramps for an E/W in a shaded suburb in winter :) Earlier in the day it's already hit the main roof and is producing a bit.
I guess your shed roof is similar.
9.6kW today despite fog and cloud early on. Have 30% of consumption covered by solar so far this month.
My shed is actually facing due south, but I have the same issue on the main installation for the E/W roofs.
Once the sun gets high enough to clear the neighbours house you can see the effect. I don't have such a pronounced effect on the west panels when the sun sets as the trees across the road hit production first.
Remember the sun only gets to a measly 15.4 deg off the horizon at noon at the moment, that's a poor slant angle in any situation.

NC6 / NC7 is not about export limits its about what is connected to the grid. Under NC6 the max total inverter size is limited to 25Amp and no export limitation allowed (you can have multiple inverters but the sum of there output is also limited to 25Amp!) . NC7 allows for higher and export limitation. So if the new electrician/installer goes by the book they could not add a second inverter as it would exceed the limits for a NC6 install.

On the other hand how will ESBN know (especially in DIY installs) other than if your exports did exceed the 25 Amp limit
8.5kwh yesterday from 8.3kw array S
