    After a good couple of 6kWh days in a row the last 2 days were each just below 2kWh total. Cloudy and overcast all day.



  • Registered Users, Registered Users 2 Posts: 4,985 ✭✭✭paulbok


    Such an up and down month. Last 4 days only yielded 8.4kWh, less than Friday at 8.6kWh. then there was Thursday better than all those 5 days at 17.5kWh.

    Still, it's covering just under 25% of consumption for the month.



  • Registered Users, Registered Users 2 Posts: 416 ✭✭rosmoke


    Slightly better today at 5.77kw from 7.4kw system oriented in all directions except north.

    Please post your array size too.



  • Registered Users, Registered Users 2 Posts: 22,213 ✭✭✭✭ELM327




  • Registered Users, Registered Users 2 Posts: 12,452 ✭✭✭✭DrPhilG


    A rare gem today. Average for the month so far is just 2.4kWh which is lower than December.


    Last 4 days totalled 7.4kWh.

    Today's total is 8.9kWh and still going.

    Today 3kwh

    Month of Jan 97wkh

    I think Jan will beat Dec (114)

    4wkp SSE in Co Meath



  • Registered Users, Registered Users 2 Posts: 416 ✭✭rosmoke


    5.77kw yesterday, 5.77kw today from 7.4kw split across all directions except nord in Meath



  • Registered Users, Registered Users 2 Posts: 4,985 ✭✭✭paulbok


    A decent 11.1kWh from 6.84kW (@200° 🧭) array yesterday.

    Need 52kWh from the remaining 6 days of Jan to match December, so not looking likely. But just need 7.5kWh to surpass last January.



  • Registered Users, Registered Users 2 Posts: 200 ✭✭Granolite


    Close to 200 degree orientation here too Paulbok. We only have our 5.6kWh roof mounted solar installed 24 hours and in our first day of generation yesterday got a total of 10.1kWh AC power yield. Grid tied so we ended up self using just 0.9kWh for the day while exporting 9.2kWh to the grid! Our total house electricity demand for the 24 hour period was just 3.6kWh so we fairly outsripped actual use in terms of generation for the 24 hour period. Happy enough with that so far!

    Already giving it some thought. We could have stored just half of the 9.2kWh generted and easily covered the domestic electricity use and heated water too. Have an eddi diverter included as part of the install It just needs wiring up to new water tank going in next week.

  • Registered Users, Registered Users 2 Posts: 1,482 ✭✭✭DC999


    Congrats on getting setup first off :) I'd say let it settle and see what you can use. There's a fair learning curve in terms of when you use power and when it's available when you first get solar. I'm only live since end of the summer and while I knew how much kWh we used per year, I was surprised to see the daily and weekly spread of that. So look at the inverter stats.

    And you've an Eddi that can send the excess to the water tank. So that's your battery. You could send all the excess to the HWT for now until you find your feet with it. Then the excess isn't going back to the grid. You'll get FIT from the date the NC6 form is registered. Might take a while to appear as a credit on the bill, but will make it there.

    Then you can see what else you could turn on to use it, like the washing machine.

    An EV in the driveway will soak up excess once it gets above 1.4kW (which the Zappi and others need, though it can pull the balance from the grid if needed). I've some low watt electric rads plugged in so they use the solar, and means the gas heating is needed less.

    There's be days with your 5.6kWp that you get 1kWh for the whole day - cloudy or rainy days winter days. Write those days off and expect nothing for solar. Everything is a bonus on those days.



  • Moderators, Sports Moderators Posts: 19,192 Mod ✭✭✭✭slave1


    If you generated 10kWh in January you are going to be consistently in excess over house load/EDDI for a good 6/7months of the year. A battery would be a big undertaking as that would require not just a battery purchase but a hybrid inverter also (assuming you don't have one) which will mean offloading your brand new one.....



  • Registered Users, Registered Users 2 Posts: 585 ✭✭✭axe2grind


    First full day, 18.2kwh from 8.69kWp south facing. I never anticipated that so much could be generated in January. And the sun didn't appear till 11.20.



  • Registered Users, Registered Users 2 Posts: 416 ✭✭rosmoke


    Have to say .. I'm jealous with how much space some folks have on their roof. I could only fit 16 panels of 460w giving me 7.35kw and that's house + extension.

    6.23kw here today in Meath. I was in city centre all day and the coast line was constantly sunny while inlands was cloudy :(

  • Registered Users, Registered Users 2 Posts: 989 ✭✭✭Busman Paddy Lasty


    16! And large panels at that. We got 5, yes a whopping 5 on the rear and 4 on the side hipped roof. 345W panels.



  • Registered Users, Registered Users 2 Posts: 2,743 ✭✭✭yankinlk


    Do u have a smart meter? At least you would get paid measured export. Battery is expensive route after install, unless you DIY.

    Some cheaper options are to setup devices that consume electricity on timers and use smart plugs.



  • Registered Users, Registered Users 2 Posts: 200 ✭✭Granolite


    Hi DC999, thanks for welcoming me to the solar PV adventure. Its great that people are so interested and willing to share their advice on here. Of course its not a one way street and yesterday stayed cloudy all day and we only recovered 2.3kWh for the full 24 hour period. I did run a dehumidifier for two hours at 250 watts through yesterday afternoon and solar electricity ran it and the rest of the domestic baseload. Despite the reduced solar yield yesterday we still produced more than our total electricity use (1.13kwh) for the same period (We use gas for our cooking and heat the house and hot water using an oil boiler, so our electricity demand can be quite low).

    I'm hoping the sun makes an appearance today as I've the dishwasher programmed to come on in 3 hours time to try and capture some of the anticipated solar yield forecasted by met eireann today!


    That is reassuring to hear. Thankfully, despite opting for a grid tied set up I asked the installer to install a hybrid inverter as I felt we would rue not having the option to install a battery down the line. I'm not in a rush to do so yet. I'd like to monitor it for a while and as well see how we perform as regards FIT savings / credit on our electricity account with EI.


    We have a smart meter installed but we are still signed up to a 24 hour standard rate "non-smart" contract with EI. If there is a delay getting the NC6 form submitted and approved I do hope we can still recoup the value of exported electricity we have produced to date rather than having it given back to the grid free of charge I hope that doesn't come across as too greedy! Do you know if this is the case?

  • Registered Users Posts: 180 ✭✭cloughy


    Feed in is from date nc6 is received as far as I know even if you have a smart meter, I don't think they backdate based on what's been sent, but still waiting my first FIT, smart meter, solar installed Sept, NC6 sent in Nov, so should see next billing what paid, as little exported in Nov-Jan,



  • Registered Users, Registered Users 2 Posts: 2,743 ✭✭✭yankinlk


    They defintely don't backdate - I got screwed by ESBN for "losing my nc6" according to my installer.

    I am on Deemed export BC im not using a SM. I assume if you dont opt-in for SM then u are ALSO on Deemed/fixed FIT rate. IE all that extra units is not going to get u any money. Then you are better to increase your self-usage of daylight! @Granolite

    Things are improving in Dublin.

    11kwh so far today. Not much left in it today I think.

    281kwh so far for January. Thats an average of over 10kwh per day for January so far with a few days over 20kwh.

    Average for Dec was just over 7kwh per day.

    to be fair 65% of the production is coming from those 5 panels facing South, need to trim the trees and waiting for sun to get higher to benefit from the rest.



  • Registered Users, Registered Users 2 Posts: 1,242 ✭✭✭Galego


    I was a hard-core anti battery leader but got blessed when my installer had no non-hybrid inverters in stock so had to fit a hybrid. Two months later, I now own 3 batteries...haha.....I cant imagine solar without batteries now. Even if they dont make 100% financial sense, in my case they certainly do! It is so self-rewarding in days like today to have full batteries from pv production and we are in January! Yeap eddi is great but.....

    See how you get on but exporting s***s even if you get paid fit imo.



  • Registered Users, Registered Users 2 Posts: 1,242 ✭✭✭Galego


    Wow that's some impressive production in January. what wkp do you have installed?

    I produced 9kwh with 4wkp in Meath SSE today.



  • Registered Users, Registered Users 2 Posts: 585 ✭✭✭axe2grind


    Cloudy afternoon in Wicklow. 6.9kwh today after 18.2 yesterday. 8.7wkp



  • Registered Users, Registered Users 2 Posts: 1,786 ✭✭✭DownByTheGarden


    Thats from 8kw of panels facing almost sse. No shading.



  • Registered Users, Registered Users 2 Posts: 1,905 ✭✭✭deravarra


    3kw produced from a 4.4kwp system.

    Roll on the longer days with lots of sunshine!

  • Registered Users, Registered Users 2 Posts: 416 ✭✭rosmoke


    9.6kw today, my biggest day so far from install date (9 days ago). 7.4kw Meath split across all sides except north.

    I keep hoping that if I mention every day that I've shading from the trees I'll trim them eventually 😂



  • Moderators, Sports Moderators Posts: 19,192 Mod ✭✭✭✭slave1


    Enjoy the trees, it's not worth trimming them if only Winter shading, wait a year and see how they shade through the 12 months



  • Registered Users, Registered Users 2 Posts: 416 ✭✭rosmoke


    Thing is I'm looking to lower my gas usage and in the winter I need as many kw as possible.

    I've an AC that I use for heating, this is 250% efficient compared to a heater that's 100%.

    It's a decent size garden so there's plenty of other trees around.



  • Registered Users, Registered Users 2 Posts: 1,786 ✭✭✭DownByTheGarden


    Just passed the 300kwh yield for January.

    It was 220kwh for December.

    Onward we go.



  • Registered Users Posts: 533 ✭✭✭The devils


    Is your ac a split unit or portable? Looking at getting one cheers



  • Advertisement
  • Registered Users, Registered Users 2 Posts: 416 ✭✭rosmoke


    It is a split AC, more broken than functional but after 15 years I can't ask more of it.

    Will be replaced with a multi split unit soon, one upstairs in the hallway and one in the extension.

    Nowadays they make them very efficient, 5-600% efficiency for a good unit. Search for SCOP rating > 5.

    They have essentially same efficiency as air to water heat pumps but without the huge cost of installation.



  • Registered Users, Registered Users 2 Posts: 22,213 ✭✭✭✭ELM327


    Actually exporting to the grid today. Battery was charged overnight as per usual however I was drawing 3-4kW by midday. Battery was in the high 80s and the BMS throttling charge rate. I've exported a total of 50kWh to the grid since the install in September 9th - 4kWh of that was today!

    I turned down the charge rate overnight.



  • Registered Users, Registered Users 2 Posts: 8,808 ✭✭✭micks_address


    Think it might be my first day over 10kwh since system installed early November.. 4kwp south east 3kwp north west

  • Registered Users Posts: 533 ✭✭✭The devils


    Thanks I have a friend calling out in a couple of weeks

    Mitsubishi and Daikin are the brands he installs. Cop value seems to be great than 5.

    A split unit would be my ideal scenario - a bit like what you where saying above.

    1 in the extension/kitchen

    2 in the landing area




  • Registered Users, Registered Users 2 Posts: 22,213 ✭✭✭✭ELM327


    finished the day with 9.7kWh



  • Registered Users, Registered Users 2 Posts: 12,452 ✭✭✭✭DrPhilG


    5kWh today. A poor month.



  • Moderators, Education Moderators, Home & Garden Moderators Posts: 8,214 Mod ✭✭✭✭Jonathan


    14.4kWh today. 204kWh for the month (188kWh for Jan 22).



  • Moderators, Arts Moderators, Recreation & Hobbies Moderators Posts: 10,731 Mod ✭✭✭✭Hellrazer


    5.7 kWh today. Heated the hot tank back to full - to be honest the gas heating was on last night and it probably more of a top up - Eddi says it took 1.2kwh and I also sent 1.9kwh back to the grid with my backwards spinning meter :)


    Generated 64.5kwh for the month , exported 15.5kwh- not too bad considering my panels werent commissioned until the 14th January.


    Im happy with that. Cant wait to see what I get in a few weeks with the better generating weather.

    First time to comment since we went live on Friday evening.

    24kWh produced today from a 10.4 system pointed 10 degrees off South. Unfortunately only 1/3 of the batteries are currently working so the first one filled quickly. I used the Eddi to heat the water with the excess and also had a plug in oil heater for the rest.

    Previous days:

    Saturday 7.6

    Sunday 13.6

    Monday 8.4



  • Registered Users Posts: 628 ✭✭✭JaCrispy


    11.3kWh for today. 202kWh for January. Slightly exceeded the forecast of 188kWh.

    Next months forecast is for 286kWh.....they've been very accurate thus far.
