Domestic Solar PV Quotes 2024 - No PM requests - See Mod note post #1

Hi all, just had a guy out to take a look at the house, got this quote for a 9 panel system with hot water and no battery, he reckoned all electric bills covered and 3 year payback time with a few hundred in FIT a year seeing as the house is empty most of the week, very open site south facing in Limerick, does this look about right to anyone? €8562 after the grant:

He also floated the idea of putting in storage heaters to cover most of the heating in Winter aswell but is that too good to be true? Standard 3 bedroom 1970s estate house with a large extension. Can I do better do you think?

435w from what I can make out. No idea what the East/West thing refers to, does this look like a very expensive quote? Tbh from online reviews they sound like an expensive company.

Damn okay thanks.

Hi All,

Got a quote there today, in the north east, from our first installer, would be grateful if someone could let me know their thoughts,

10 435kw panels (5/5 east west split) roof mounted

Inverter

Hot water Eddie

Post works BER

Install

7,130 after the grants. (690 of this is for the Eddie and optional)

Given loss etc been told generation would be closer to 3800 which would match our estimated usage pretty much to the unit.

First time looking since buying so any steer on this would be appreciated.

Appreciate that link! Thank you!

Why arent you elligible for the grant?

Ah right never heard of that one, sorry for being lazy but how old does a new build have to be to qualify or are they barred from the grant forever?

Hi,

I just got the quote below in that I would appreciated people views on. I don't know much about solar!

• 14 x 440w panels - TW Solar (48HD435-455W)
• Hybrid inverter - SAJ (H1-6k-S2-15IE)
• 10kwh battery storage - SAJ (B2-5.0-LV2)
• Roof mounting equipment
• All labour works
• Changeover switch
• All electrical testing and commissioning 
• Online monitoring to see each day exactly what your system is producing
• BER 

€   8600.00 Final Cost to Customer after SEAI Grant

New build (no grant) - 6.16kWP - 5.3kWh battery - €8450

• 14x440W panels south facing roof (6.16kWP)
• Solis 5kW Hybrid inverter
• 5.3kWh battery

With battery €8450
Without battery €6660 (that's €1790 less)
Zappi €1600 extra gross before grant

• New build to be A rated
• A2W heat pump with underfloor heating downstairs & upstairs
• 1 x EV 51kWh
• 1 x PHEV 14kWh

1. Is this a good quote?
2. Is it worth getting battery?

• Have a 5.32kWP system (S/E/W facing) in our current home with 4.8kWh battery + Eddi + Zappi.
• Experience is that battery is useful for peak loads e.g. oven, and during emergencies as we have an emergency socket so were able to force charge battery ahead of recent storm. That being said, V2L adapter for 51kWh EV could provide for future emergencies
• No experience of heat pumps so interested to hear from others on that
• What do people think about charging battery off-peak and discharging during peak hours?

Thanks

About €2.5k too expensive. My setup is somewhat similar, just didn't need optimisers

Thank you. Do you not need the optimisers because they’re all together on the same side of roof or because you just don’t think they’re necessary in general? Mine will be on 2/3 different sides of roof potentially and both guys I contacted said I should get them.

From what I’ve read 14 optimisers shouldn’t explain a 2500 difference.. does seem expensive to me. Waiting back on another quote today to compare.

I got a crazy quote a few months ago of 12,800 - 1,800 = 11,000 for 12 panels 5.1 kWp and a 5.00Kwhr battery.

I just received a quote of €11,135.00 - €1,800 = €9,335.00 for 16 panels and a battery.

Panels: 16 x 435 Watt Panels (TWMNH-48HC435) - 6.96 kWp…

Battery: Sigen Battery with LED 5.38kWh of Battery Storage and a Sigen Hybrid Inverter

The panels apparently have a manufacturer warranty of 25 years. I am thinkin' this is a much better deal than my previous quote but then I see others for far more panels who are quoted only a small bit more. Anybody have recommendations for the Galway area?

we paid €100 per panel for the mounts for our flat roof.

Hi all,

been following this with interest for a while, got a quote today and looking for some feedback. Looking at Wompa1's post I reckon we're both talking to the same company!

I'm not sure what the difference is between

7.395 kW Total Solar Power

and

5,611 kWh per year

in the quote. If I put 5 into the David Hunt calculator vs 7 I obviously get very different results!

TW SOLAR (Hefei) Co. Ltd

7.395 kW Total Solar Power 17 x 435 Watt Panels (TWMNH-48HC435 Full Black) 5,611 kWh per year

Sigen Energy Controller Single Phase

5 kW of Inverter Power  Sigenergy 1 x SigenStor EC 5.0SP 10.0 Year Warranty

Sigen Battery with LED 5.38kWh of Battery Storage Sigenergy 1 x SigenStor BAT 5.0 .0 Year Warranty 

Warranties: 25 Year Panel Product Warranty, 30 Year Panel Performance Warranty, 10 Year Inverter Product Warranty, 10 Year Battery Product Warranty

BER included, no Eddi required

The consensus on this forum seems to be that there is not much of a difference between panels in terms of performance or reliability. And that you should look to getting as many panels as you physically can fit, at the cheapest possible price.

Batteries are very useful, for loading up on cheap power at night (if you have a smart meter)

Your electric heater will run as usual. Whether that power is coming from the panels, the grid or the battery will depend on what power the panels are generating at that time, and if that isn't enough to cover your house load, how much power is available in your battery. You don't need to do any switching yourself. The inverter takes care of that.
