    Happy days. If you get on well and the installer isn't on the list PM me with the name and I'll put them on the list.

    Although by the way just to clear this up, nearly all batteries are put in parallel, I know the weco batteries has a high voltage mode that they can be put in series, but I don't know what inverter supports them.

    PV novice here.

    can a reputable electrical contractor carry out an installation if they major components are purchased by the customer?



  • Moderators, Home & Garden Moderators Posts: 6,058 Mod ✭✭✭✭graememk


    Thats no issue at all.
    other than the grant, there is another catch too :

    The supply and fit of a solar install is at 0% VAT but if you bought it yourself you would be paying 23% VAT.



  • Registered Users Posts: 1,345 ✭✭✭Negative_G


    Thanks for the response.

    I guess it boils down to what can be achieved versus the outlay.

    I Suppose that buying materials yourself would lead to a better cash deal scenario.

    What do people make of this offer? Sigenergy system is also setup for v2h bidirectional system for compatible EV's down the line



  • Moderators, Home & Garden Moderators Posts: 6,058 Mod ✭✭✭✭graememk


    How does it compare with other quotes you've got? For a 5kWp ish system with a 8kWh battery?

    When AI is mentioned the bull sh... Alarm goes off in my head for marketing * hand wave*

    What would be the chances of you changing to an EV that has V2H, and getting the V2H charge point too? (Remember that isn't included in the quote either)

    Also getting an aversion to cloud stuff, things done last forever anymore and what happens the inverter when the internet dies or the company shuts up shop?

    KISS- keep it simple



  • Registered Users Posts: 3,511 ✭✭✭pah


    About €1200 more than the same system but with 5kWh Battery, so there or thereabouts. If I wanted to KISS I should buy a 30 year old car with wind up windows etc, rather than something modern over the last few changes?

    I would definitely consider a v2h EV such as EV9. The potential to never again pull another unit that wasn't solar or off peak is very appealing tbh. For a system that will take 5+ years to payback and hopefully run for many more I think a bit of futureproofing is a good idea. Obviously that's not included in the price but can be added easily down the line due to the modular design. Who knows what way the electricity market will go the way the world is right now? A couple of years ago the UK was facing planned power cuts due to shortages.



  • Moderators, Home & Garden Moderators Posts: 6,058 Mod ✭✭✭✭graememk


    Not too bad of a premium for it. Especially when they include a full changeover. I dare say the changeover work is worth the extra cost.

    Does the EV6 have v2H/v2G? I know it has v2load which is very different (basically is a generator), the sunsynk inverters have an aux input which allows a generator input.

    But a good few of us are running on night rate with some able to run on 3hrs at 5c.

    There isn't many v2H/G charge points on the market yet, the ones that are very expensive.

    Things I'd pay attention to is

    Amount of panels,

    Charge/discharge rate to and from the battery,

    Battery size,

    Changeover switch

    The what I don't put a value on is the AI stuff and the v2G as it's still vapourware at this point in time.

    And also being able to work without the app. Apps are a bonus but it shouldn't require it.

    The inverter should be there for 20+ years all being well.

    If you are going this route get the electrician to buy the panels + other equipment and price the full job supply and install and he can 0% rate the everything.

    That being said I was looking at going down this route with my electrician and in the end it was more hassle and probably would have saved little. You also need a roofer, there is a lot more work for the roofer than the electrician in a solar install. The roofer likely won’t be used to it so will take longer - same for the electrician. Overall it made more sense to go with an establish solar company after I sat down and thought it all through.

    If you can do the job, do it. If you can't do the job, just teach it. If you really suck at it, just become a union executive or politician.



  • Registered Users Posts: 547 ✭✭✭PCDub


    Seems a very good quote, wouldn't mind knowing who the installer is.



  • Registered Users Posts: 3,911 ✭✭✭GTE


    Thanks for this.

    One installer was very pro panels (he said we could get 20 installed, split between East and West roofs.

    The other I'm looking at is saying 18 panels and a 5.3kWh battery.

    I'll update the spreadsheet to see who is offering better value.

    The Jeremy Clarkson attitude in me says more power (more panels).



  • Registered Users Posts: 5 Mario101


    Reading through this I was just wonderiing: Is victron not a top brand anymore?

    New memeber, just trying to figure stuff out :D



  • Registered Users Posts: 13 Michael1927


    Can I ask what the opinion on the supply of different types of panels is and does it make much difference when deciding on a company to go with. I live in the Northwest near the coast. Are Glass Glass panels a necessity over others?

    Company is A is supplying 14 x Luxor Solar LX 420M panels which are glass glass. + Solax Power X1-HYBRID-5.0 inverter. Total cost after grant €7695

    Battery would be an additional €1950 for SolaX 3kW - EDDI would be an additional €595

    OR

    Company B is supplying 14 x 430w Jinko Solar panels Monocrystalline = 6.0kwp system. + 1x solis hybrid inverter + Dyness battery. Total cost €8100 after grant.

    Or without EDDI €7750.

    Should I go for company B and get a better price with battery, I don't think I need the EDDI, or should I be going for glass glass panels?

    Any advice would be appreciated? Thanks.



  • Registered Users Posts: 134 ✭✭ohlordy


    Hi, basic cost question here, I have no detail of the specifics of the parts to be supplied.

    Quotation for 2kw system (5 panels, roof space limited without any options to locate elsewhere), 2.4kw battery, inverter etc etc.

    7500 inclusive of grant.

    Expensive?

    Thanks



  • Registered Users Posts: 2,523 ✭✭✭bullit_dodger


    Panels are just panels basically. As long as it's a reputable brand, there's really nothing in the difference between the various manufacturers, other than price. You might get a better degregation over 25 years of 1-2% with one brand over another, but honestly, it doesn't matter. In 25 years panels will be more efficient, so go with the cheapest kwp/€ now. I can't speak directly to glass itself, but think it's a bit of marketing hype - but maybe I'm wrong.

    Eddi is a personal choice. In todays electricity supply market an EDDI will never make you money. That's right, you will NEVER make any savings with an Eddi. Why? Well if you night rate electricity is say €0.10/unit, and your export FIT payment is €0.20/unit - it just makes more sense to heat your water on night time rate and export the leccie you make during the day and get paid more for it than heating the water. That said, it's not all about money. I bought my Eddi at a different time before FIT, and I still use mine as it was intended….and electricity rates may change. We may not have these good FIT rates or cheap night time forever.



  • Registered Users Posts: 875 ✭✭✭keno-daytrader


    So it's 9250 (without grant) for 5 panels and half a battery? I would run 5 miles from whoever gave you this quote. We've seen some cowboy quotes here, but this one really takes the biscuit.

    Try plugging that into the David hunt calculator which is a good starting point when getting quotes.

    Get lots of quotes to help you decide.

    It's 7500 before grant, 5900 net cost to me, I badly worded that!

    Still seems expensive and David hunt calculator says so too.

    Is it generally the case that smaller installations are more expensive per kW due to their small size?



  • Registered Users Posts: 13 Michael1927




  • Moderators, Science, Health & Environment Moderators Posts: 10,079 Mod ✭✭✭✭marco_polo


    Seems like a reasonable quote from a local installer with good reviews. I know they have done some other houses nearby as well. Davidhunt.ie gives it the thumbs up from a cost perspective.

    Any concerns about equipment?

    17 x Trina 440w

    Huawei Inverter

    4x optimiser

    K2 mounting

    Eddi

    Ber included.

    Coming in at just over 8k after Vat.

    5kW Battery option little over 3.5k seems a bit steep hadn't really intended going for this at this point in time anyway, I guess this a downside of the proprietary nature of the Huawei tech stack.

    Hi first time commenter long time reader,

    Looking for help with companies in my area,

    Finding a good few companies done want to touch my roof (blue Bangor slates) and the ones that do (4 so far out of 9) are averaging 8k for 10 panels 435w, water heater and no battery,

    Calculator says it's 2k over, I don't was to pay premium if possible

    Any way I'm in centre Louth area, looking for any help with companies you would recommend, have tried a lot of what's already posted



  • Registered Users Posts: 875 ✭✭✭keno-daytrader


    Looks to be a solid quote. Do you really need the Eddi?

    If you join the Facebook group with 55k members, you will get great advice on quotes and naming of actual companies that is not allowed on boards.

    Both websites were a great help when I was researching solar

    What brand is this? Ad pictures all low res.



  • Registered Users Posts: 487 ✭✭Metalpanic


    Looks like a Huawei inverter with a sticker on the top. Maybe the installer adding branding?



  • Registered Users Posts: 6,692 ✭✭✭deezell


    Of course, you're right. They were advertising 8 panels system starting €5500 on adverts.ie, very neat installation images. Based in Athy.

    Thanks for sharing, they are good quotes. My brother in law got a quote for a similar system for €13k after grant. When I showed him your post and he showed it to his installer, they magically dropped their quote to about €8k
