That's a lot of exporting!
For summer, yea. Low roof angle generates a lot in summer. An EV in the next couple of years will take some of it. And I’m ok with exporting some of the year, regardless of FIT.
March and April were close to consumption, so the marginal months look like they can be pretty mostly covered.
That's a beast of a system. Just added 2.3Kwp DIY (exactly South facing) but that only brings me up to 7.6Kwp.

Your rocking there for sure - that EV can't come quick enough :-)
Nice one, great to see us eeking out every possible drop of PV, as I'm driving around I do find myself with aspect envy these days

Sorry only saw this post now. Yes nice to hit over the mw for month considering was quite cloudy for lots of it. Two inverters - 6kw solis 5g hybrid and 2.5kw goodwe standard single string inverter. Solis has 6.98kwp of ground mounted panels and goodwe has 2.88kwp DC on roof
Is it just me or last year's August was absolutely brutal?
This year might even hit 900kwh
I'm nearly beating my July figures and we've 2 days left to go - and july was decent enough. Right now I'm on 547 units and I did 559 in July.
Current Actual compared to forecast is 121% for August, and 2 very sunny days to come!!
Nice, what size?
Well the numbers are already in - August is my best month beating May's numbers.
May had higher highs (cooler panels) but August just had more days above 20Kwh for me. Notably - my import numbers are up this month (from 28Kwh to 102Kwh) but I expect that July holidays meant i just used less power that month compared to this month.
tldr; From here and into winter - my need to use Night rate and Load shifting will increase - the days are drawing in and sunshine is NOT getting over the trees early enough to fill battery or heat water anymore - so i need to boost with the Eddi more. My oil tank has been idle for months thankfully - and i dont expect to need to fire it up until November - unless i find it cheaper to heat water during the day. Getting a fill today to top me up before it gets crazy.
Call a tree surgeon !!!
Ahh the old "Can-o-petrol-and-zippo problem" I see - LOL
Too soon, still generating for a few hours......
I have removed all South facing obstructions - and felled a West facing obstacle. Im keeping the remaining ones topped... but the East Facing early morning trees are loved by the missus. I might convince her to top a few next year. I know which ones are in the way after observing for a year. :)
6.2Kwp Monaghan ( August last year was 511 kWh )
6.84kWp south facing, Roscommon. 4.8kw battery.
August 2022
869kWh generated (660 forecast) ,😁

Total consumption 710kWh. 218kWh discharged from battery. 291kWh exported
69kWh imported (no day/night meter, but bulk imported during night, early morning)
44.0kWh generated best day (9th & 11th Aug)
10.7kWh generated worst day (15th Aug)

Array 1: 4.1kWp SSW with Winter Shading, 3.3kWp NNE
Array 2: 2.73kWp SE, 0.91kWp S, 3.64kWp SW (all neighbourhood shading/optimised)
561kW imported (two EV household)
1,146.4kWh Generated
938.4kWh consumed
320kWh diverted to Eddi
376.9kWh diverted to Zappi
Approx 2427.2kms of range into the EVs
Highest was 55.5kWh

80% self sufficient (excluding EVs)
63% self sufficient (including EVs)
Monthly cash saving based on average daily load and all non-load items like dishwasher/washing machine/immersion at night rate, €95.45
Great month but skewed by install of Array #2 mid month on the last day of the glorious weather. Most happy with the PV into EV rate. Milestones in the month include passing the €1k mark in electricity cost saving since inception, passing 10MW in production since inception, breaking the 50kWh daily generation and passing the 1MW in monthly production.
799KW generated for August with 141KW to the Eddi. 7.2KW South facing in Dublin. Best day was the 8th generated 38KW.,

Diverted Eddi 106, Zappi 144
Very happy with system, even though self use is relatively low this month, but with some deemed CEG by end of year.. 🌞🌞

Two more 400w panels going on to my boundary fence vertically on Friday orientated west as I have two spare ports on my microinverters, so why not.

Been a good month. Two installations. Installation1 is the original one (1.52Kwp East/3.8Kwp West) in south dublin.
Installation 2 is the 2.3Kwp south facing one the shed. Only operational since Aug 5th or so. Still did an impressive 211Kwhr which at ~€0.30/unit, that's a nice €60 assuming I was to use it all myself (which I know I didn't and a lot of it got FIT exported). I'm on deemed export, so it's much to a muchness for me.
Some milestones: Broke €1,000 in overall savings since I put the system in, in late Oct '21, which would put me on track for a 7-8 year payback for everything (installation 1 only)
For those of you who are interested, south Dublin had a pretty good month compared to forecast.
I had better/higher months of course (May & June) but August felt relentless with day after day of 20-25Kwhr. Smashing.
Great month. Thought I might get my first MW but no…6.9kwp South facing.
4.83kWp south facing, Dublin Fingal
635kWh generated (best month since install)
207kWh exported (67% solar self-consumption)
38kWh imported (13kWh day, 25kWh night)
31.1kWh generated best day (10th Aug)
8kWh generated worst day (16th Aug)
You folks are quick off the mark!
Roscommon, 4550Wp, Azimuth: 136° (SE), Slope: 24°
😀
South Roscommon, 8.16Kwp, facing 210° at 35°
Total generation 1084kWh
Consumed 583kWh
Energy from Grid 91kWh
Energy to Grid 347kWh
To the Eddi 155.9kWh
To the Zappi 260kWh (approx. as we had a couple of night charges due to a few trips)
To the Battery 154kWh
Best day 10th with 53kWh
Worst day 1st with 13.4kWh, only 2 days where it dipped below 20kWh and 4 straight days in the 50's.
Was our best month to date, really was a great August, breaking the MWh.
Running about 68% self use as we had a good few days away when the weather was good.
Savage.
