    Cavity wall insulation looks extremly expensive, attic insulation looks ok but depends on what your getting. And has been said solar looks expensive.



  • Registered Users Posts: 5 MyBrotherKnowsKarlMarx


    The attic insulation is one of the most ridiculous. I estimate I can do the work myself for ~€700 in materials.

    This is what they are proposing for the works:

    Insulation top up to meet 300mm requirement. Top up of 300 mm loft insulation throughout the attic roof space – 83 sqm.

    This price also includes:

    1X Attic Hatch 600 x 600mm

    2X Stira Cover

    It's 14305.71 + VAT (16236.98)

    The heat pump price looks expensive (unless they're replacing all your radiators as well and depending on the size of your house).

    Did they come out to survey the house before giving you the quote?

    You can ask them not to include the solar if they won't reduce the price on it and assuming you can meet the BER requirements without it.

    We had someone out to take some measurements but not a proper survey by any means. The next step they are advising is to have a HEA assessment which we are told will be a full survey too.

    I think leaving out the solar and getting just the cavity wall insulation + windows and doors + heat pump may be an option if that brings us up to B2. Then we can look at solar separately


    This is the spec for the heat pump. A quick search is showing me a price of €7,190.00 for a similar unit with a cylinder so probably overpriced too

    Installation of a 7.5Kw Air to Water Mitsubishi Ecodan Heat Pump complete with integrated cylinder and heating control upgrade.

    This price also includes the replacement of 9 radiators (including surface pipework).

    Pylontech, Soluna, puredrive or BYD. Using the BYD myself and I can't fault it, easy to ad on but hard to get and pricy

    The attic is easy, a few mates to help out and payment in beer

    No but I wouldn't be full up to speed on what's being offered at the moment.

    The Dyness stuff is OK, it wouldn't be my first choice TBF



  • Registered Users Posts: 40 saccaromyces


    Insulation foam woudn't cost you that for 83msq and would be much more efficant. I think you need to walk away from this company and have a rethink. Maybe different companies for each project, they would all specialise in there own field and probably better buying power.

    Each project are either grant aided or available for tax relief. A bit more work for you but from what I'm seeing a lot of monies saved. Your call.

    Get the cavity walls done; you can get the individual grant for that and it will cost a lot less if you shop around.

    get your attic up to 300mm; shop around you will easily beat this price. You can get a grant.

    Shop around for windows and doors some seriously good prices can be had if your willing to consider going with windows imported from Poland. Make sure your going for a product with a U value of 1.0 or lower. Usually you will pay an extra 5-10% for triple glazed; I think it’s worth it.

    and shop around for PV quotes.


    don’t spend any money upgrading your heating system until you have done the insulation / windows / doors above and see what your house is like to live in. Try to run your existing boiler at its lowest output temperature for a month in winter and see what happens.



  • Registered Users Posts: 40 saccaromyces


    Thats great advise, that exactly what I did and never changed heat system as couldn't justify the price now with house insulated my heating cost dropped dramatically. But you do need to shop around



  • Registered Users Posts: 10 alineysean


    Got quote. €14,400 after grant (€2400) for 5.8kw below, not sure if go for it.

    You should be able to get the same sized set up with just as good equipment other than Huawei for about 4k less nearly. Check post #3697 similar system but with a 10kwh battery included.

    Don't expect anything from life, just be grateful to be alive.



  • Registered Users Posts: 118 ✭✭simpsimp


    I signed off on an almost identical system in February, for €8,350, ex grant*.

    (5.85 PV Array; 5kW Inverter; 5.2kW Battery)

    I know prices have risen a little in the interim, but definitely shop around!

    *I did get the €600 battery grant, so €9,000 would be the equivalent today, I suppose



  • Registered Users Posts: 1,469 ✭✭✭MAULBROOK


    Once again the unnecessary Huawei tax strikes again. Keep looking



  • Registered Users Posts: 10 alineysean


    Great advice

    Wasn't aware of any huawei tax.



  • Registered Users Posts: 10 alineysean


    post #3697 could find it.

    Would be glad to get something cheaper.

    DYI is much cheaper but roof is too high, wouldn't take a risk.

    😄😄



  • Registered Users Posts: 10 alineysean


    Sorry I couldn't find post 3697,

    Just rechecked my post and found that I typed "could" instead of "couldn't.

    Thanks a million.



  • Registered Users Posts: 1,469 ✭✭✭MAULBROOK


    The Huawei gear is generally more expensive for what you get. It's good gear but not worth the extra ie Huawei tax.

    I really appreciated your advice,

    Looking for another installer around connacht with a better price.

    Most installers are changing a lot when grant is involved.,

    Shop around is definitely the way.

    Hi all !!😀,

    Looking for opinion's on three Quotes : I was originally looking at getting 12 panels, but think i might be able to push to 16. Want to eventually be able to add a battery so a hybrid inverter is a must and also have the option of adding a couple of panels to the west facing side of the house in the future (not sure what quote 1's hybrid rating is, so might have a issue there). seems very hard to get value at the moment , especially when you are aware of the real cost of the inverters/ panels ect... !


    Quote 1:System size: 6.8kW - PV Panels – Leapton 400w by 16 - All black Panels.

    Panel Mounting – Renusol

    Inverter - Solis single phase 5G inverter.

    Price after grant - €8,040 + 700 for hybrid inverter( which i want to future proof)


    Quote 2: 4.8kW - PV Panels – 12x 400w Jinko N panels (around 250 euro each for extra panel)

    Inverter - Sofar 6kw hybrid inverter

    Price after grant - €8,090


    Quote 3: 16 x Jinko 415w Neo N-Type 

    1 x Sofar 6kW Hybrid (HYD-6000-EP)

    1 x Eddi with Hub

    1 x BER

    1 x FSS

    Price after grant - €10,883

    Hi guys,

    Thank you for all the help so far. Still researching and still getting quotes trickling in for a 6kw system.

    What is the general consensus in terms of battery. A rep (whose company uses Huawei battery) told me that a battery wouldn't be needed unless you're going for a much larger system?



  • Registered Users Posts: 1,469 ✭✭✭MAULBROOK




  • Registered Users Posts: 1,469 ✭✭✭MAULBROOK


    Get a battery 5kwh minimum. The Huawei gear is pricey and your stuck with a expensive Huawei Battery.



  • Registered Users Posts: 12,556 ✭✭✭✭AckwelFoley


    Batteries and eddies for hot water are luxuries. If you have the right plan with your service provider, you'll be a long time if ever get payback on them

    If money is particularly sensitive, always choose panels over battery or eddie.

    Panels generate money, batteries or eddies don't.

    The above only makes sence since we get paid for excess, your excess revenue can offset your use if you can shift as much use to the night rate and super night rates.

    If I knew 6 months ago what I know now and see how i can benefit from raw generation, I'd skip the battery and eddie and buy 8 more panels.

    I spent 10k. 3ish of that was battery and eddie. Every day, good or bad I'm making money. But now, completely bought into it I see the benefit in the bank and want to get an electric vehicle to cut out the majority of the 400 a month we spend on diesel.

    I find it brilliant to be less concerned about rising ESB and eventually diesel costs.

    Solar is an investment. You won't get the same return on your money from the bank, or from your pension. The key to the return are the panels.

    Bottom line. Panels panels panels



  • Registered Users Posts: 648 ✭✭✭Moreilly


    Yep, quote 1 does look a bit better, I just sent them a mail to see if I can pin down exactly what rating the hybrid inverter is in case I want to add more panels to the western side in the future.....



  • Registered Users Posts: 1,469 ✭✭✭MAULBROOK


    Aim for a 6kwh hybrid inverter anything less is taking the piss.

    You also need to take into account if you live in an area prone to power cuts the amount of panels you have is useless unless you have a battery to keep essential things working. Most people won't be in that scenario but I am, 7 power cuts this year and the batteries got me through them all. It all depends on your circumstances at the end of the day. I agree as many panels as possible.
