Quote received...

7 x Solarwatt Vision 60M 315W panels.
Solis Hybrid Inverter with Monitoring system
Pylon tech US2000 2.4kWh Battery

I’m 500m from the sea hence the Solarwatt Vision which supposedly has glass on both sides for better protection from salty air....

cost after grant is €5,896

Yay or nay....

unkel

Nay.

You do not want to buy a battery with a system that small. If that is all the panels that you can fit, get a quote for the cheapest panels (forget about that "protection") without a battery after grant but also get quotes from non-SEAI installers (for a non-subsidised system)

Bit high but not outrageous. First quote from my installer was €6,600 for the same battery but 18 x 310w panels and a 5kw hybrid inverter.

I'm sceptical about the double glass labels. I had a guy try to flog them to me even though I'm about 3 miles and on the other side of a hill from Lough Swilly.

I would say outrageous!

Cost after grant €5,896, you can get that size of an array (with no battery and no hybrid inverter) for €2,400, paid over ten years.

The battery / hybrid setup is costing you almost €3,500 extra, more than doubling the total cost and will never be recouped.

Are they putting in any wiring for any future expansion you might do?

No, we have no space for a bigger array.

@AndyBoBandy: With that size system you won't have any excess left to charge the EV either. Just saying...

What inverter are they putting in. Considering it but need to check if I'd get the grant

What would the general advice be for this scenario?

-S/SW facing. No shading from trees.
-Not sure of roof size area. It's a 4 bed semi.
-Medium sized family.
-No EV.
-Home office always in use during the day,so electric used during the day.


The main things I'm wondering about are, size of system, battery or no, and move to night meter or no.

Thanks.

Size - as big as possible (irrespective of your current consumption. It's possibly safe to say EV not YET. And even if you start with a small setup, make sure you get panels installed in corners outwards, so that room is left for expansion later.

Battery - generally No, but do your sums. If stored power replaces full rate power, you maybe save 20c per kw at most. It takes a lot of 20c's to repay maybe €2k for a 2.4kw battery. And battery life would be 10 years.

Night - evaluate your usage. It makes sense if you do have an EV for sure, or if you have a Powerwall of some kind and charge the batteries off the grid.

garo

People here have installed systems ranging from 2-7kW. I would say 4.5 is the median. Unless your usage is really low I would get at least 4kW.
Best thing to do is get a few companies to come out and quote you. Ask for prices both with the smallest battery they have and without because if it is a grant install a battery adds 1200 to the grant.
Other factors you should consider are where will you site the inverter (and battery if getting one). And how the wires will go from the panels to the inverter and then to your fusebox. Best to get ideas on this from the installers who call out and decide what you are happy with.

Yesterday, was just under 4kwh total, but today so far, 12kwh, a fully charged battery and a tank of hit water so far.

Yesterday 2.1kw, Today 19.6kw.
I'm up to 20 panels (6.2kw) now and if i had more space I would fit more.

The simple answer is money and space to fit them.

Panels are daisy chained together with the MC4 connectors on each panel. The male on one connects to the female on the next.

So you simply break into the chain anywhere

That's why I'm amazed that there aren't more self installs being done. The only difficult bit is the roof rails.

And that's why people getting small installs should get them installed in corners to allow additional panels to be added if space permits

I wouldn't be confident putting up rails and panels.

Would then need a spark to so the wiring.

You certainly don't need a sparks. It's clicking push fit fittings together. A male plug fits into a female socket. You cannot go wrong, even if you tried.

You can add into the middle of a string or add on at either end, or both

Don't need a sparks as long as you're;
Familar with acceptable inverter Voc overheard for cold temp uprating combined with lensing effects.
Happy you can't melt anything in the new configuration.
Checked the inverter for absolute max allowed Imp

That's all the technical I can think of.
The liability etc. I don't care to mention..

Is there even a single sparks in Ireland who could / would do all that?

Put away the can of worms Unkel!

You threw that can into this thread

Only thing is there not listing Solis Hybrid Inverters
Can anybody confirm

There is an ie version of it, should have the hybrids in it. Its linked to midsummer as when your done it will fill your cart there.

Hello everyone,
Been following this thread with a while, so finally decided to take the plunge and get quotes for a new year install. My electrical bills at the moment are approx. €1200 inclusive of vat and charges. My biggest power consumer is a geothermal heat pump which i run on nightsaver.
I received 2 quotes which i hope ye can advise if they are good/bad or ugly!! Based in Cork with a south facing house.
Quote 1: Monaghan Company with Cork Office

12 x 335 watt Mono Trina PV Module
Solax Battery 4.5kw
Hybrid Inverter
Hot water diverter
Gross €13858 (grant available €3000)


Quote 2: Cork Company

12 x Solitek Standard 325W black Panels-

KSTAR Hybrid inverter-

CATL 5kWh LFP battery-

Eddi hot water diverter-

Remote Monitoring-
K2 Roof Mounting System
Gross €12297 (grant available €3000)


Thanks for looking and i look forward to your comments and advice.

2 of the most scandalous quotes I've seen for a while.

My first quote was 18 x 340w panels, Solis 5kw hybrid inverter, Solic water diverter, 2.4kWh PylonTech battery and a Zappi 2 car charger for €10.2k as far as I remember. €6,600 after grant.

First of all (other than telling them both to go and jump) get an individual quote pricing each aspect. See how much the batteries are costing.

Secondly ask yourself if you really need them. 4-5kWh of batteries on a 4kw system might be more than you need and the battery is very expensive. You may well be better getting half the size of battery as you get as much grant for 2.4 as 4.8 for example.

Hi DrPhilG,
Thanks for your reply, i had thought that but both companies tried to sell my consuption with the Geothermal unit
Would you mind PMing me your installers details please?

Yeap same as dr Phil my setup is identical to yours though 4k cheaper. Phil PM'd u the name I presume. Good lads . They have been back to me already tidying stuff up and due back again with my recent issues which is always a good sign that they will come back after he dosh is handed over.

PM sent.

They both look on the high side.

What size inverter are they quoting.
How long is the warranty on the battery and Inverter and dose it include a BER.
No harm in knowing for yourself that is.

slave1

Crazy quotes, as others said...get quotes with small battery like Pylontech 2.4, also get quote excluding hot water diverter as this not economical regarding payback.
Both those quotes need €4K trimmed off them at a guesstimates when you get smaller battery and no hot water diverter

Now this looks alot better:D

thanks for every ones feedback to me.


Still waiting on a few more

Brilliant to see that thanks to the help from others on boards.ie, people are saving themselves thousands!

garo

Lose one of the two batteries and the Eddi and see what the price is then. You can then decide whether they make financial sense for you. Decent quote otherwise. Also I would say ask for 2 or 4 extra panels and see what the additional cost is.

Yeah 4 more panels is more valuable than an eddi, esp on the duller days.

And if we get a FIT, even at about 5-6c, any extra panels installed at reasonable cost, will pay for themselves very quickly.

I'd been thinking of swapping out my 4.8kWh pylontech batteries and putting together a DIY Leaf cell battery.

If there was never a FiT then this would take me nearly off grid for half of the year, if combined with some more panels cheaply installed.

Probably not that sound a financial decision but more of a project.

But a FiT may well kill the plan.

In 3 months (Aug-Oct) I've exported 220kWh. With the peak months of May, June, July still to come, it wouldn't unreasonable to think I'll export 600+kWh per year. A feed in tariff at 4c a unit would only give me €24 a year.

Whereas saving that 600kWh at night rate would be €48.

So I'd be coughing up another few grand now, to save an extra €24 a year. In other words adding about 90 years to the payback time...

OK the export/excess would vary if I added panels but still no good.

kanuseeme

Surely being off grid for 6 months is worth more than 24/48 euro?

You only gave your export figures, how much do you import?

Would a bigger battery not reduce imports also? Surely a big battery would get you through a cloudy day and replenish the next ? A extreme week would it not give some benefit to charge that battery at night? I know it would be cents per kWh. it all adds up.

AndyBoBandy

Another quote received;

7 panel 2.1kW system with hot water diverter: €5,900 (€4,100 after grant), and they include the new BER after the install.. (minus €500 if we don't get the diverter) I'd like to thing we'd get something during the summer for hot water, as winter the heating coming on heats the water tank..

Batteries probably pointless for us as we are both home during the day, so there'd never be enough excess (from 2.1kW) to put anything meaningful into a battery.

They don't say which panels they use, but its the crowd Electric Ireland use..
edit: the panels are Peimar SG310M

Yeah maybe...

A friend of mine built his own 12kWh battery from an old Leaf and he's giving me ideas. He recently bought another full battery too.
