Colors reversed but I have the same chart (albeit I start mine at last Nov - LOL)

Should be good to clear 5-10% over June's estimate (here in Dublin)

DrPhilG · 29-06-2022 10:51pm

Barring a disaster tomorrow I'll meet my expected target for the month.

Mind you my target is just what I got last year, adjusted for the additional capacity. So monthly target is 801kWh. I'm now on 784kWh so only need 17kWh tomorrow.

paulbok · 30-06-2022 7:01pm

Gonna be 5kWh short for the month. But over 100kWh ahead of forecast for the year.

Edit: ended up 2kWh ahead for the month afterall 😁

700 in May and 657 in June. First year so still learning what's normal.

really happy with the self-use rate. 5kw battery on a 6.6kw system.

June 2022

6.1 kWp South facing in Cork

Generated 742 kWh

Used 327 kWh (44%); exported 415 kWh

Money Saved on energy bill from PV for this month 327kWh * €0.30 = €98.10

Estimated Potential FIT @14cent/unit = €58.10 (not realised as don't have smart meter and I am with EI so just a hopeful guess)

Overall for the month it was below expected and even less than March, but overall my system is about 11.5% over the estimated PVGIS SARAH estimate. I included this month how much my PV system saved me on my electricity bill as its a simple calc and it should be useful for people to see the potential.

bullit_dodger · 01-07-2022 10:40am

South Dublin rocking in with 5.3Kwp split (1.5Kwp East/3.8Kwp West)

Not one "perfect day" with smooth curves. Shame as I was quite hoping to see what the max daily system generation is. The monthly max I did get was 33.93Kwhr (June 20th), but that was beaten by 34.6Kwhr on May 19th, so there's probably 35-36Kwhr in it.....if we had a clear coolish day in June. Maybe next year. LOL

Still overall pretty happy with this as it's close to May and was still 14% over the PVGIS estimate.

Dare I say it.....days are getting shorter now folks <sniff>

Total Generation: 764kWh (224kWh consumed directly, 158kWh into battery, 382KWh to grid)

Best Day: June 20th - 41.0kWh

Worst Day: June 5th - 7.0kWh

Total Consumption: 420kWh (91% Solar:9% Grid Import (39kWh))

Milestones & Info:

Monthly Expected FIT €53.48 :: Money Saved on Energy from PV :: €85.69 :: Total Savings €139.17 for June.

Expected FIT since Feb 15th €188.30 :: (24KWh Feb, 254KWh Mar, 272KWh Apr, 413KWh May, 382KWh June : Total 1325KWh)

THE ALM · 01-07-2022 11:43am

Energy from Grid 27kWh

Energy to Grid 222kWh

To the Eddi 165.2kWh

To the Zappi 228.7kWh

To the Battery 151.6kWh

Not a perfect day in the month with only a few over 40kWh with the best at 55kWh and the worst 12.4kWh. Up 77kWh on projected figure and down 47kW on last month, should be able to push past the 1MWh if we had a few good days in the month.

Hopefully the new batteries are on the high seas so will be able to make more use of the generation.

Housekeeping, your grid-battery-house losses look low, someone here measured them and about 9% in and out so around 18% in total

GivEnergy's batteries rock in (as per the spec) at 92% efficiency. I'm actually low (on the poor side) with 91%. The numbers I've listed are from the inverter itself, (Battery in & battery out). Sure, I guess the inverter could be wrong/lying, but without doing a couple of tests myself taking note of the ESB meter, setting the house to a super low base load, charging the battery, then discharging the battery with a known load and counting the time, or using something like,

Power Meter Electricity Usage Monitor, Maxcio Upgraded 13A Energy Monitor with Backlight LCD Display/7 Monitoring Modes/Backup Battery, Overload Warning Watt Volt Amp Meter UK Plug for Home Appliances : Amazon.co.uk: DIY & Tools

(I own a similar plug above)......it's hard to definitively say it's wrong. When we get back to wintertime and I'm charing the battery to 100% from grid at nighttime I might give it a lash to see if it's right/wrong, but yeah, the spec is 92% or so they claim.

4.5 only for the eddi for a month? That doesn't seem like a lot ?

championc · 05-07-2022 11:11pm

I was away for half of it, and I have 30 solar tubes too, so there were days I absolutely did not want to add more to it.

Ubbquittious · 31-07-2022 8:09pm

245kw from 2.4kwp this month. This is the first full month it has been connected. I'm already sorry I didnt put in more. I could do with at least 5kwp + tubes for heating the water because it covered only 1/3 of total electricity usage.

championc · 31-07-2022 8:27pm

https://www.boards.ie/discussion/comment/119412895#Comment_119412895

It's quite possible that a lot of that other usage could be at hours which are not covered by solar.

And with your 2.4kWp, how much did you export ? If you exported, then you would only likely export more if you had more panels.

Hopefully your self use is quite high
