Just as a guide for you, my neighbour just installed

18x 450w

5kw inverter

2x 10kw batteries

Changeover switch for power outage

BER

Post grant €14300. Each additional panel + €90

ted1

just got a quote which seems to be very good

14 * 450W JA panels

5kw Giv Energy Hybrid Inverter Gen 3

+ installation hardwares etc.

3,720 after grant.

Another crowd wanted 8,800 for 11 panels

Was recommended not to bother with a diverter as they add costs and only have a 2 year warranty. Was told to just set a timer on the immersion for an hour during the sunniest part of the day. Makes sense.

Even better idea, set the emersion for 3am when its 6cent/kWh (if you are on a smart rate) and export the PV for 18cent!!

Just wondering what battery installation prices are like?

Friend is getting a system installed soon and they have offered to add a 5 KW dyness battery for €2400.

I can buy the same battery for €800.

The are already installing a hybrid inverter so that's not it..is it that actually connecting the battery to the inverter is a big job? Or is it that you have to buy extra cables or something like that? Or maybe you have to have an electrician connect the battery?

Some of the lads here could guide you through connecting it, if that's how much they charge for the battery how much is the rest of the system! It should be a relative simple install and no qualifications needed that I know of.

Got my first quote, waiting to get a few more but it seems decent according to the solar quote analyser tool.

22 x 435W bifacial panels (9.57 KW)

Sig Energy 5 KW inverter and Sig Energy 8KW modular battery

14k all in.

Don't qualify for grant.

We're a new build with heat pump and EV and WFH, yearly usage likely 9000 - 10000 Kwh.

Anyone have any on thoughts on whether this is good or bad? This can't run off grid during power outages, it'd be another 2k to get the Sig Energy Gateway for this, don't think it'd be worth it. Could also go with less panels but I have the roof space and each additional panel above 14 panels is 200 extra so probably worth maxing them out now?

I have the same setup , just no battery , price seems very similar to what I paid taking grant and no battery into consideration. I would hazard guess it is same installer.

In terms of maxing out panels.. I went with the general advice given here to max out. In winter it will for sure make a difference. In summer (days like this) you probably have some wastage , depending on whether they are all on the same roof/direction. If I had to do again, I would max out again. Better looking at them than for them.

I've 20no 460W panels, 5kW SigenStor Interter and 24kWh (3no 8kWh) SigenStor batteries for €16,200 post grant.

Think that'd work out slightly better than yours (Sig batteries are pricey enough)?

oleras

https://www.boards.ie/discussion/comment/123448402#Comment_123448402

8kWh ~2.5k and the 5 ~1.5k i think i was quoted.

Soarer

https://www.boards.ie/discussion/comment/123448510#Comment_123448510

Yeah, so €14k plus €5k for the extra batteries is €19k total. Mine was €18k pre grant.

Is the investor not undersized for the amount of panels ?

Soarer

https://www.boards.ie/discussion/comment/123449871#Comment_123449871

No. The SigenStor inverter allows for 200% oversizing, so anything up to 10kW array is fine.

deezell

https://www.boards.ie/discussion/comment/123449871#Comment_123449871

Depending on the inverter, battery and bms, the inverter may be able to deliver the excess or some of it to the battery on occasions, say 5kw to grid, 2 or more kw to the battery. Having an oversized input is cheap, some posters here only paying €90/extra panel on the day. This greatly extends the period in which a 5kw inverter can actually deliver 5kw, especially in winter.

deezell

China can burst national grids by remotely dumping battery power and over voltage in a coordinated attack, that's the inference from this Reuters article. Was Spain a test? Answers on a foil hat only.

Hi.

Could I ask who you got that quote off. It's very good.

Thanks

Padre_Pio

https://www.boards.ie/discussion/comment/123442960#Comment_123442960

seems to good to be true.

Checked my last invoice, the bones of 3k for 11 panels, inverter, cable and fixings, ex VAT.

That's just materials.

ctomas

Quote for the parents house in mayo:

Total Cost After Grant: €6983
6 panels at front, 6 at back, bungalow.

 5.34 kWh Solar System
12 x JA Solar Fully Black Bifacial Panels (445W each)
Solis Hybrid Inverter 
Hot Water Diverter (Eddi)

Seems a bit high…

Does anyone have an Ecoflow Power Ocean inverter and batteries? If so how has your experience been with it and the app etc? Have a quote for 14k (no grant) for 5kw Ecoflow Power Ocean inverter, 10.2kwh Ecoflow batteries, 22 Jinko 440W panels (9.68kw) and a changeover switch.

The mostly likely alternative option is a Sig Energy Sigenstor 5 KW inverter and Sig Energy 8KW modular battery, with 22 x 435W bi-facial TW panels (9.57 KW) with no changeover switch or Sig Gateway. It's a roof install so bi-facial is probably not much benefit. Gross price for this 13700 (no grant).

Finally got my panels in yesterday. Sparkies needed tomorrow for final installation and commissioning.

The amount of stuff that could've went wrong did go wrong. Whole thing was delayed by about 8 working days. Outside of the installers control though, but as a good will gesture, they threw in an extra 460W Aiko panel! So I now have 13no. south facing and 8no. north facing, 9.66kW total (I know the north won't be as productive!).

Looking forward to getting it all commissioned now and having a play with the SigenStor app.

Is installation of north facing panels on the rear of a Nth/Sth aspect home in Dublin worth it ? Will they be productive to any decent extent ?

Hyzepher

Is their anywhere to get a reliable rating of the various installers?

deezell

84 listed on Trust pilot.

https://ie.trustpilot.com/categories/solar_energy_company

deezell

Not all solar companies in this list, though they're on Trust Pilot. Nextgen-Power for example, recently mentioned here, 89% 5, 4 and 3 star reviews, 91 reviews in total, but are not listed under this heading 'Best in Solar Energy', though many companies with only one or two reviews are. Actually I'm curious about anyone's experience with them, without publishing quote details which is verboten on this thread, more about the general experience customers have had. They've had a dozen unfavourable reviews on TP.

ruffmut

How does this look price wise. What is the Goodwe brand like compared to Solis?

PV 6.160Kw System14 x Trina 440W Solar PV Panels
Goodwe 5Kw Inverter & 5Kw Battery
Mibet Mounting
Electrical Equipment
Labour Cost of Electrician & Roofer.

Total after grant €8000

Would it be worth putting an Eddi in as well for the hot water?

ted1

https://www.boards.ie/discussion/comment/123500422#Comment_123500422

it’s expensive, no need for an Eddi, just a well back your electricity and heat your water off peak.

Or put a timer in your immersion for the sunniest patients day.

...Ghost...

Got a few quotes for the inlaws this month. 12 jinko 440W panels. 8 optimisers. Solis hybrid 5kW. BER included.

BEST quote down to 6,500 after small negotiation. Well known installers. And they even cover the grant, so the inlaws don't have to wait for seai.

Hyzepher

Has anyone had a NextGen installation? Was it a pain thet they don't do the BER/Grant directly?

Zonda999

Hi all, would appreciate some advice as I've have narrowed it down to 3 quotes:

House is a recent build so no grant applicable

Company A:

18 x Longi LR5-54HTDB-425M 425W Panels

Solis S5-EH1P5K-L Inverter

3 x Dyness PowerDepot H5B 5kWh Batteries

Battery socket

11,200 EUR

Company B

19 x 435w QCells Q.Tron 3 BFG All Black Solar PV Panels

5kw Q.Home Core Hybrid Inverter (15 year warranty)

2 x 6.86kWh Q.Home Save Battery (15 year warranty)

Manual Changeover Switch

14,495 EUR

Company C

18 X JINKO 440w panels

5 kwh SIGENERGY Inverter

2 X 8 kwh SIGENERGY Battery

SIGENERGY Gateway (Automatic UPS)

15,600 EUR

i'm actually veering towards Company B at the moment. The first quote is mighty competitive but i know is the most basic spec stuff being sold at the moment, and the company is relatively new to the game, so after care is an unknown (but I haven't heard any bad reviews at all). Also, I would much prefer the manual changevoer switch that that company don't seem to offer. In terms of company B, the supplier is the most local and I suspect the most reliable in terms of any issues. Also, the Qcells stuff has a really long warranty - the only thing putting me off is that its NCA battery tech and I'd prefer LFP given this it going indoors in a utility room. that and the price premium over the first quote. its alos the lowest overall battery capacity. Lastly, in terms of the Sigenergy quote, this looks to be the go to premium option for installers at the moment. Unsure if really worth the premium but its popularity must be well founded on some level.

Would love to get some thoughts on the above.

Are you sure you can get the SigEnergy Gateway installed? I thought Networks hadn't approved their use yet. Things move quick though.

As for your quotes, I only have experience of the Sig stuff, although I may have gotten a quote from the same company (based in Cork near a resort?). If you're putting the battery inside, the Sig batteries have 5 methods of fire retardation build in. Might be something to consider.
