    i have a smart meter for just over a year now but am on a 'legacy' price plan with EI which does not give me the detailed breakdown. is there any way for me to obtain a HDF file so i can use it on energypal.ie? or would that info not have been collected without a 'smart' plan, so does not exist yet?

    there's a certain irony in that i believe EI won't give me the data till i switch to a smart plan, but that info could be key to convincing me to switch to one.

    edit: i just copped the CSV file *is* the HDF file.

    I have only started to look into solar recently. I see a lot on here about SunSynk/Deye.

    Are there many installers installing these, particularly in the Limerick/Munster area? I've searched but can't find much. I'd like a beginner-friendly setup initially but want something that can be integrated with home assistant/automation eventually when I get time.

    Any suggestions/thoughts would be appreciated. Thanks

    Small update, I made my mind up and have booked in for the meter tails upgrade next week and am going ahead with the 10 panels, so wish me luck!

    Just one more question…. should I get my roof cleaned before installation?!? It's a bit mossy.

    I know if you exceed €400 per person net on microgeneration in the house, per year, it's taxable. How is that calculated? Based purely on what you the utility owes you?

    I.e. would that be on your net electricity use rather than strictly on your microgeneration alone?

    One of our neighbours (five or six doors down) recently had their roof powerhosed clean, and we were wondering was it in preparation for a solar install.

    I'm glad it wasn't our next door neighbour, I'd say everything in their garden would have ended up coated in a fine layer of dirt and grit.

    Your supposed to declare it on a self assessment I think. (Eg my revenue or something)



  • Moderators, Category Moderators, Arts Moderators, Sports Moderators Posts: 52,631 CMod ✭✭✭✭magicbastarder


    Yep - but do you declare income from microgeneration alone, or do you declare the net figure including cost of consumption?

    E.g. if I sell €1k worth of electricity, but also consume €1k worth, is the figure I declare €1k or €0?



  • Registered Users, Registered Users 2 Posts: 4,779 ✭✭✭Ezeoul


    I was always advised that a roof should always be soft washed, never power-washed. But that is for another day's research.



  • Moderators, Home & Garden Moderators Posts: 7,074 Mod ✭✭✭✭graememk


    Doesn't stop people from doing it!

    But generally a roof isn't "water proof" it is just very good at shedding water. With slates/tiles water is designed to just run off, and the felt underneath. If not done properly you could blast water up under the slates/tiles and soaking the felt, which is more like a rain coat that breathes, not a plastic coat that the water just runs off

    microgeneration export only. So if you export 500 euros worth. You'd be taxed on 100 euros.
    You can additional names to bill thus increasing your allowance. so two people allowance is 800 euro



  • Registered Users, Registered Users 2 Posts: 7,850 ✭✭✭Calibos


    Is there a limit?


    EG. 5 adults living in our House. Bill is still in my late mothers name. So when we get around to removing her name and adding my fathers, we could actually add myself, my 2 brothers and one of the brothers Fiancee’s names to the bill too? Giving us a €2,000 export allowance?

    Or is the multiple names on a bill only allowed for owners/spouses and/or lodgers etc


    (We all pay 1/5th shares of the ultility bills)

    (Just starting Solar and battery research phase atm. Install probably still years away)



  • Registered Users, Registered Users 2 Posts: 622 ✭✭✭idc


    Who ever you add has to be willing to accept full responsibility of the bill, that was the only criteria we had with Energia - wife had to speak to agent and confirm she would be responsible if I failed to pay.
    Pretty sure there are other users here with husband/wife and 2-3 adult kids living at home all named on bill to get large export allowance.

    Just had the panel install done and the installers didn't end up going into the attic at all, instead fed the cables through from overhead. They appear to have just cut the membrane and fed through, I would have expected them to go through the overlap a few cm lower than the point they chose. Is this normal for solar installs, should they be making the cut watertight again before they finish? Hopefully the photos attach correctly for once...

    Did you apply for the grant, just mentioning because a firemans switch is required and does not appear to be in place (within 1.5m).

    If you didn't get the grant then you can ignore



  • Registered Users, Registered Users 2 Posts: 3,751 ✭✭✭CR 7


    No, not eligible for the grant(new build).

    They probably should have taped the membrane, especially given that the hole is dead-on-center of the rafter spacing where water might route. But they should also have at least clipped the cables onto the rafter and not leave them hanging as they did.

    Folks please help me,

    I have solar for the past 18 months 10 panels, 5kw battery all by Huawei and it's working well.

    The battery was a later addition and I was at work when it was installed.

    I want to set up battery to take from the grid nightly cheap rates but I don't know how to set it up, the installer is not answering his phone, I think the company was sold.

    I currently use the Huawei Fusion solar app, i also have the myenergi app but I don't have that fully working. I think I was originally advised to just use fusion solar app.

    Any advice greatly appreciated

    log in to the web version https://eu5.fusionsolar.huawei.com/unisso/login.action#/home/list

    Then go to the dongle/network connection for the inverter (it's the node above the inverter in the list on the left).

    Go to configuration and scroll down to "EMS control" and youc an either change your Time of Use times or set it to maximise self consumption or fully fed to grid. You can only edit the TOU times when TOU is active.

    I'm sure someone posted a link in one of the threads where you can put in your quote and it'd tell you if it was overpriced or not.
    Anyone remember what that was?

    Fair play @graememk 👍🏼

    Hi all. Fairly new to this, have read a lot of this thread, and I know it's a bit of a hot topic, but could anybody chime in on the pros of getting a battery in our scenario?

    East/west split and have been looking at systems between 5-8kwh. Quite low annual usage at around 3.5kwh in a new-ish build with an A2W heat pump; not eligible for grant. No EV atm, but might transition at some point so want to make sure we're "future proofing".

    I understand the basic tradeoffs of installing a battery (with upfront cost being the main con), but I'm unsure how to do the calculations to estimate usage & gains with vs without. Any help appreciated; TIA.



  • Registered Users, Registered Users 2 Posts: 2,681 ✭✭✭ECO_Mental


    If I were getting a battery (and I am) you need to be covering your day rate usage at least eg 8am to 11pm. Dont worry about the EV as this is a battery anyway and you will be charging this at the cheapest rate.

    Like everything else to do with PV panels and battery get the biggest you can afford, you will never hear people say that they got too much battery or too many panels. I would say at a minimum you shoudl be maybe looking at 10kWh battery. IF you have a heat pump during the winter this can be using a lot and shifting as much of this to a 6cent kWh rate and out of peak rates will save you a good bit.

    I have a friend who got E/W spilt and 5 kWh battery but he has gas heating and cooking and during the summer months they are paying him money with all the export. He says himself he should have gotten a bigger battery.

    Still learning here too.

    What I found a huge help was using ChatGPT or Gemini. Tell it what you're planning or thinking of doing, your useage, your tariff, everything. It'll do all the calculations for ya.
    What even more helpful for the AI is using this website. https://re.jrc.ec.europa.eu/pvg_tools/en/#PVP
    You'll have to run the calculations twice, once for each side of the roof. But run the first, copy the table into a Word document or something, then do the same with the second. Paste both results into the AI, and it'll give you a more accurate calculation.

    Don't forget, if you do get a battery, you can charge it very cheaply every night, and whatever you have left over come the end of the day, you can force discharge it again for extra export before charging it cheaply again.
