Daily pv production



  • Registered Users Posts: 445 ✭✭ DownByTheGarden

    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 Posts: 1,179 ✭✭✭ 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 Posts: 1,179 ✭✭✭ 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 Posts: 550 ✭✭✭ axe2grind

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

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

  • Registered Users Posts: 1,748 ✭✭✭ deravarra

    3kw produced from a 4.4kwp system.

    Roll on the longer days with lots of sunshine!

  • Registered Users Posts: 410 ✭✭ 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: 17,372 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 Posts: 410 ✭✭ 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.

    Just passed the 300kwh yield for January.

    It was 220kwh for December.

    Onward we go.

  • Registered Users Posts: 305 ✭✭ The devils

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

  • Registered Users Posts: 410 ✭✭ 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.

    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 Posts: 7,349 ✭✭✭ micks_address

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

    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 Posts: 19,361 ✭✭✭✭ ELM327

    finished the day with 9.7kWh

  • Registered Users Posts: 11,480 ✭✭✭✭ DrPhilG

    5kWh today. A poor month.

  • Moderators, Education Moderators, Home & Garden Moderators Posts: 7,589 Mod ✭✭✭✭ Jonathan

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

  • Moderators, Arts Moderators, Recreation & Hobbies Moderators Posts: 10,076 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: 591 ✭✭✭ 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.

  • Registered Users Posts: 752 ✭✭✭ DC999

    Welcome to the solar club :) I'm only 5 months ahead of ya

  • Registered Users Posts: 2,964 ✭✭✭ irishchris

    19.8 generated today to finish the month nicely. Roll on February!

  • Registered Users Posts: 84 ✭✭ olympicweights

    Only 5.5kWh today, similar to yesterday. 209kWh for the month, 208kWh last month

  • Registered Users Posts: 410 ✭✭ rosmoke

    10.84kw today, 72kw since going live on the 19th.

    6.4kw split across everywhere except north 😅

  • Registered Users Posts: 410 ✭✭ rosmoke

    Bear in mind SCOOP is a rating given per country so in a colder country ratings will be less as they are less eficient in lower temps. Same unit will show different ratings in different countries.

    Was looking at Mitsubishi and Daikin too, I've my eyes on a Mitsubishi split unit, will share the models tomorow, think it's pretty efficient.

  • Registered Users Posts: 5,268 ✭✭✭ Chris_5339762

    Not too shabby... 137kWh in January from a 4.5kWh system on a 3kW inverter down in Cork. And that included a few days of downtime in the middle (during mist/fog!)

  • Registered Users Posts: 823 ✭✭✭ eclipsechaser

    Thank you! Nice to finally be able to join. It's a good time too as things start improving from here on.

    Just went live on Monday with a 8.0kwp system, 4.0kwp west (~ 250 degrees) and 4kwp east (~ 70 degrees) with a 5kw battery. 5kw on Monday and 8.3 yesterday. Based near Mullingar.
