Yes to both
Its a benchmark to aim for. Its after grant and dose not include a battery.
By the way if anyone is reading this and looking for companies to quote could you please say what part of the country your in.
Some nation wide companies can be more expansive the local ones.
Hi all,
finally got a reasonable quote for 4.7kw system - at €1k/1kW mark (if I had a grant, which I don't):
14 x Qcells 335w split-cell all black mono PERC
Solis Dual MPPT String Inverter
All those panels will take 24 sqm - that is twice over allowed exemption. Has any of you dealt with local council in regard of this ?
-Solis Hybrid inverter 5kw to future proof extra panels later date and wifi dongle for inverter app
-4.8KW battery
-14 panels JA solar 310W on a west facing roof
-Eddi water heater for immersion
-Zappi 2 car charger untethered and myenergie hub
7000e after grant net cost to me- Nearest quote was 3-4K ontop of this quote.
Sound lads in Enniskillen, cover nationwide! - sale guy is very helpful to deal with I had lots of questions as new to solar pv and EV driving.
sounds like the guys I used for my install. Was very happy with them. Best of luck with it.
Hi guys,
I'm looking for installers in the Cork city area. If anyone can PM me some contact details that'd be great. I'm looking at about 15-20 panels on a S-SW bungalow roof with a battery and at least an option for EV charging for when i get around to changing the old dinosaur juice guzzler.
Any answers to my earlier question on moving from prepay to billed?
Sorry not a bloody clue.
Mabey call the supplier your going with and they should know, I would say its not the first time its been done.
Another quote;
19x Qcells 335w (6.37kW) Ground mounted
Solis Dual MPPT String Inverter (6kW)
BYD B-Box Premium LVS 4kWh (Cobalt free)
7700Euro
So this time with a 4kWh battery system - no grants etc.
want to minimise the foot print overall though as it will be ground mounted
Bloody hell that's good. Starting to see good quotes again I think.
Thats more like it, No grant, with a battery.
could you pm me the details of who you got this from please ?
thanks
Could you pm installers details please?
Appreciate if you could PM the installers details, thanks.
I just got my first quote from one of the crowds that are heavily advertising down here in Cork and it was a little steeper than I expected! He said I needed:
8 panels
1 small battery
1 diverter
1 BER cert
And after the the grant was taken off it would be €8,400...is that a reasonable cost?
You need more detail than that, what size panels/battery, no mention of inverter.
In any case about €2k too much
8 panels? Even if they are 400W panels this is way too expensive.
Saw 465w panels online yesterday, big boys!
Day light robbery. Looks like the customer is paying heavily for the advertising.
Can any one advise on a good operator in the Cork are for this lad.
I have just been quoted 8300 for ( after grant )
8 * 375 watt panels
Inverter and Battery - no water heater.
Based on what I am seeing here that's not in the running?
No. At least 3k more than what it should be assuming a small battery. Is that a rather active company?
Hi,
He didn't mention the size of the panels, I presume he'll give more details in the email quote. I think he said 2.75 battery if that makes sense? He may have mentioned an inverter. I only have a small house of about 1200 square feet so I doubt the panels are very large but I don't know for sure.
Hi Folks some feedback on the following would be great and thanks
17 Trina Solar 400w (6.8Kwp)
Flat Roof mouting system
Hauwei 5kw inverter
Hauwei 5k Battery
Diverter
10k after grant
That goes into the can do better category. But getting close.
What happens when the inverter is underspeced for the amount of panels? 5kw but potential (if unlikely) 6.kw count from the panels?
Here's a laugh to get your morning started.
Recent quote I got;
Cost of a 6kw 16 panel system €14300 inc vat
Seai Grant €3000
Final cost to you €11300
This system would give you a saving of €1250 in year 1 and for the next 25 years
6kw Solis hybrid inverter
iBoost
iBuddy
BER not included
Ridiculous price and very 'generous' assumptions for payback.
right size inverter question:
if I understand it correctly,
the power rates of the panels are DC rates (peak rates actually), the inverter rates are for output AC (or are they?).
What size of the inverter should be installed for 4kW solar array ?
Should "Recommended max. PV power" exceed theoretical 4kW of solar ?
I understand here in Ireland we don't get the full sun, but when we do (once in decade) would it not be dangerous to have undersized inverter ?
ps: i am maxing out the roof space (S-SE), so there will be no extra panel added in the future.
So, in fact, the inverter is oversized it has a Max 7,500 Wp DC input and a 5kw AC output, reading many forums on this solar journey is seem the industry is preferring to oversize the PV array to the inverter due to the fact the inverters are way more efficient when running close to the max before any inverter clipping starts
All very new to me so forgive the stupid questions. Everyday is a school day!
It's a balancing game. If the inverter is undersized relative to the array - and I am talking max theo DC output vs AC output only - then you get higher efficiency in the operating curve but suffer from clipping. Most inverters these days have an almost flat efficiency curve after 15-20% so this is only applicable below 20% rated max. So if you have a 5kW inverter you are inefficient below 1000W and if you have a 6kW inverter you are inefficient below 1200W. The increased efficiency helps in the winter when you wouldn't be producing much.
