Received a quote this morning for:

16 x Bauer 445 Watt Panels (BS-445-108M10HBT-GG)

1 x SUN2000-5KTL-L1 Huawei

Mounting + Installation

€10500 including SEAI grant. Standard roof, install should be straightforward.

Way over your 16 Bauer quote! Could you PM me the names of the companies?

Thanks.

That sort of usage equates to around 18kWh per day. You should definitely be getting a battery.

Hopefully getting solar installed in the next 2-3 weeks .
I’m looking to see what people are doing to work out which is the best smart tariff . I just started looking at the apps from energypal and kilowatt.ie . So I’m asking what methodology are people are using to work out their best plan .

going with a ground mount . 9.8Kw with 15 kw battery . Annual consumption 4600 . No EV yet but most likely in the next 2/3 years .
no heat pump or electric showers . I had planned for load balancing using the battery to feed the house during the day and recharge at night .
lastly it’s a solis inverter so I ask in advance of installation what is possibly with that inverter

many thanks. .

Saw the following advertised for €5K by one of the many solar companies at the ploughing:

-10x505W Tier 1 panels

-5kW hybrid inverter

-Free BER

-Complete install

I would say..

In my opinion , that's a large system for the amount you consume so you will be exporting a lot! Pinenergy have the best export rate @ 0.25c . I would recommend going for the Pinenergy EV tariff plan. Fill up the batteries between 2am & 5am. The rate for the rest of day is 0.41 cent I think but you won't be consuming that with your battery size

thanks a lot Sponsorgate. Yes it is large but most likely an EV will be in the in there in the next 2/3 years .
I’ve a few weeks to nail down my plan for the year coming .

Recently got a quote for Ecoflow Hybrid Inverter, 19 panels and 5Kwh battery for €11,500. Same company had previously quoted €13,500 six months ago for similar spec except it was a Sigen Hybrid Inverter and 8Kwh battery. Not eligible for SEAI grant. Price is all in including installation and whatnot. Is this reasonable?

Are Ecoflow inverters reliable?

Hi all, great thread.

I've upgraded my windows and insulation, now it's time to jump on the solar express.

First quote just in - what do you think?

System: 5.34kWp - Battery Ready - 7 Optimisers - BER

12 panels: 445 Watt Panels (JKM445N-54HL4R-B) - Jinko

Hybrid inverter: SOLIS 5 kW

Total without battery €9,820 (€8,020 after grant)

Total with battery €11,446.00 (€9,646.00 after grant)

I'd have most panels east and west, and a couple on south. So nice balance over the day, hence thinking of not getting a battery but leaving the option to add it later. Cheers.

If anyone has recently got a quote from a northern crowd can you DM me?

I feel like they are taking me for a ride, and just want to compare. Thanks.

I have a few quotes that it would be great to get feedback on:

1) 15 panel - 6.75kW system, JA 450 panels, 5kW EcoOcean Inverter, 10kWh EcoFlow Ocean battery, changeover incl. €9,945

2) 16 panel - 7.2kW system, TW Solar 450 panels, SigenStar EC 5.0SP inverter, SigenStor BAT 10.0, changeover not included. need to get quoted. €11,000

3) 12 panel - 6.0kW system, Leapton Sonal 500 panels, Sigen Hybrid 5.0 SP2, SigenStor BAT 10.0, €9,100 + €650 for changeover.

4) 15 panel - 6.8kWh system, Jinko 455 panels, Sig Energy inverter, SigenStor 10.0 BAT 10.0, €11,614 + €2,650 for Gateway to allow changeover

My roof is kind of trick so suppliers have different number of panels costed.

It seems to be a heads up between EcoFlow and Sig? What are peoples views on each?

No 1 or 3 seem the obvious choice. Why does no. 4 need me to buy a gateway for changeover when no. 3 doesn't.

Anything else I am missing. Are the panels all the same?

Are these quotes minus the grant?

Grey123

https://www.boards.ie/discussion/comment/123888778#Comment_123888778

yes. All minus the grant.

Grey123

https://www.boards.ie/discussion/comment/123490993#Comment_123490993

Which did you end up going with? I have a similar choice to make. EcoFlow looks good, but perhaps too good?

Sigenergy quotes look a little high for me. I got a 9.8kwh(22 panels) with 2 x SigenStor 10.0 BAT for €12800 after grant.

Grey123

https://www.boards.ie/discussion/comment/123890625#Comment_123890625

I think the panels are cheap? Maybe €200 a pop?

Not sure on the panels but the extra battery is the main difference for me

Grey123

https://www.boards.ie/discussion/comment/123890732#Comment_123890732

Oh, sorry didn't notice that. What is your average daily usage to need 20kwh of battery? I think I use about 10kwh in the summer and 20kwh in the winter but maybe 6kwh of that would be overnight anyway, so I am thinking if I have another 10kwh from the battery and a little bit from solar it will get me close to the 20kwh.

Heat pump user. My average usage is 28kwh. Solar installed 6 weeks ago & have exported over 1000kwh back to grid already with the help of batteries. Charge up batteries on EV rate at night & discharge what you don't use before EV rate kicks in again at 2am. Taking advantage of decent export tarriff rate while its there.

Its different for everyone. 1 battery may be enough for you to get ROI.

Does this sound any good..

22 x 445W–465W Solar Panels

Full install, they look after all paperwork, esb connection etc, i've to hand over € 7,820 

No battery included

Hand over as in pay upfront?

Grey123

https://www.boards.ie/discussion/comment/123890866#Comment_123890866

20+ seem to be the normal. What size houses do people have or is it E/W sides filled?

The sigen homepro gateway is an inverter sized switching box and junction for all the system inputs (except batteries) which manages the changeover from on grid to off grid connection of your inverter, and change over is instant and interruption free. I managed to find a UK price for this unit, about €1000 ex vat, so theres a 160% markup for installation on your quote, commissioning takes only ten minutes according to the sigen site. Other versions of backup might be more mechanical, with manual switchs to be thrown, and the inverter being set to run in off grid mode. Some inverters have built in backup output at reduced power, maybe 2Kw, and the installer would divert a portion of your home circuits to this, usually lights and living space outlets, boiler power and fridge, but excluding utilities, cooking, heatpumps, immersion, anything heavy. The advantage of the heavy duty sigen gateway is its capacity for complete backup, if the sun is shining and you have a big battery, and the bigger units can take in a generator output also.

I presume thats your middle of winter usage? Mine with an air to water is about 22kwh in the worst winter month last January. It drops to about 9kwh in summer.

Sound like you are exporting about 24kwh a day over the last 6 weeks, basically running an energy offset business!

Grey123

https://www.boards.ie/discussion/comment/123891102#Comment_123891102

Ya I understand that the benefit is automatic. If I only have 10kwh of battery I may be better off not having heat pumps working / cooker and to only have it run lights and outlets to try and get a bit longer out of it.

Grey123

Does anyone have any experience with Start Solar for installations and EcoFlow products? Anything it doesn't do? Any issue with the company?

Yes, that's my yearly average. In summer, I average around 15/20kwh & in winter it can jump to 55\60kwh if temps are low & heat pump running all day.

Yes, my peak in one day in mid August was 42kwh exported (combination of solar & battery discharge).

My first bill came a few days ago. Export Units 1,093.807 at €-0.20 per unit €218.76CR

What output would be reasonable to expect from a 7.8kwp system (19 panels). Half facing south, half west.
Total generation year to date is 2.9mwh, and I am concerned that is low generation.

Anyone any idea if that is a reasonable number based on info provided?

I have 6 MWh year to date on my 6.1kWp system, but I have perfect orintation all 100% facing south. I would have though that you shoudl be getting more than about half wat Im getting. As con747 says put into the PVGIS website, that sould give you an estimate to within 10%
