Epic month! My Solis inverter says I generated 761kWh and my Home Assistant and ShellyEM is saying 776 kWh... Used nearly 42% of it which I happy enough with until my EV rocks up in the summer some time.
6.1 kWp system, South facing, outside Cork City.
Great month just 1Kw less than August total this month 234.5KwH last August 235.3 2.5Kw system in Louth West facing
Best day today 31 12.3Kw worst day 2 March 1.1Kw
Hit 2100kWh since install 23 April 21
Massive month for PV (4.83kWp south facing, Dublin Fingal)
564kWh generated
37kWh exported (94% solar self-consumption)
109kWh imported (90+% night rate)
Diverting surplus PV to oil radiators has made a serious dent in our gas usage too. Boiler hasn't been fired since St Patrick's day.

I was away for two weeks. Look at the export :-(
I generated 764kwh in total. Madness for March.
March Stats
6.2kWp (2.8 south/3.4 west), 20kWh battery, Zappi & Eddi – Donegal
Generation – 523.1kWh, a whopping 65% increase from 2021
Export – 2kWh (down from 20kWh in 2021
Import – 279.4kWh, decrease of 28% from 2021. Also managed a 95% night rate usage.
Best day – 28th 26.4kWh
Worst day - 2nd, 2.1kWh
Days with zero purchase - 7 (and another 5 with less than 1kWh.
Overall my consumption was up by 14% from about 700kWh to 800kWh so to reduce purchase and export so much is impressive, and all down to the whopping battery.
Was a cracking month.
3.24kw west facing
289.1 kwh
Best day 14.9.29/03
Worst day 1st and 15th 3kw
6.1kw dual array. 12 panels south ground mounted and 7 west roof mounted. 5kw battery and eddi.
491.5kwh this month.
4.8kW EW Dublin. 10kWh DIY battery
March 2022(kWh):
Production: 396 (291 predicted, 332,4 last year)
Consumption: 674.6
Import: 305(101d, 204n)
Export: 26.4 (25.6 last year)
Best day: 28th: 19.8
Worst day: 2nd: 1.1
Sadly, I didn't cross 20 kWh this month. Still produced 35% more than expected.
Is your system performing correctly ? That output looks far too low for that sized system, and based on the weather for the past two weeks alone.
I have 3.3kWp and generated 370kWh. I think @SouthWesterly has a system around your size, so hopefully he posts his monthly stats for you to compare.
Fingal, 5.78kWp (1.36kWp SE, 2.38kWp SW, 2.04kWp WNW)
Total: 391.5kWh
Best Day: 31st - 20.4kWh
Worst Day: 2nd - 1.1kwh
Loving it.
2.8KW array, South Facing, Meath, No Battery installed, 10KW battery here :-) Need a firmware update on inverter to use :-( Battery would have knocked €50+ off the bill.

That was last months, when I went to post I saw my comment from last month sitting in the box :-( I've posted this months, and yes, a huge improvement
March 2022
South Dublin. 6.7kWp - 2.5 n/e, 4.2 s/w, 2.4KWh Pylontech battery
generation 556kWh (up 110% on Feb)
Consumption 797kWh
Best 27/3 - 28kWh
Worst 9/3 - 2.3kWh
I think I need to plug the car in more during the day, or maybe get a bigger battery
7kwp S facing Dublin with 5kwh battery
Didn't think I'd have to push myself to "waste" so much excess in March 😂
A big 🖕 to Putin courtesy of the Irish weather!!!
Like everybody March has been a great month.
8.16kWp Midlands facing 200° 35° angle, 5kWh battery, Zappi, Eddi and several heaters on smart sockets.
Generated 880kWh
Used 456kWh
Battery took 168kWh for a self use rate of 71%
256kWh went back to the grid
115kWh imported, mostly on night rate
11kWh to Eddi
182kWh to Zappi
DIY 10 kW battery, you know if you want to :). Then sell the Pylontech for €1k and you have a 7.5kW battery upgrade for about €500
Yup - stellar month for March here in South Dublin. 5.3Kwp (split 1.5Kwp due East/3.8Kwp due West)
4.1Kwhr to the grid for the month. Must "have a look"....:-)
Main thing is that it's a €100/month. Physiologically that's a great milestone to achieve.
5th Month
Dublin - Lucan - March 22 - 7.12kW total installed (S: 3.45kW, E: 2.41kW, W: 1.38kW). E&W Optimised. 5KWh Battery, (30 S & 22.5 E/W degree pitch).
Total Generation: 610kWh (196kWh consumed directly, 160kWh into battery, 254KWh to grid)
Best Day: March 27th - 28.7kWh
Worst Day: March 2nd - 3.2kWh
Total Consumption: 474kWh (77% Solar:23% Grid (109kWh))
Milestones:
Passed 1MWh generated since install last October
Also 1MWh generated since the start of the year
1st Month Generation Exceeds Consumption
Thats some serious export to the grid, and I can only assume that number will grow?
Do you have an EV?
254kWh would equate to around 1,700km in my car!!! I put about 85kWh in the car in March, and am looking out at pretty much free motoring now until September!
I know and potential summer numbers will be huge, sadly no EV in the short term but we are happy to supply the grid until we can use it.
First full calendar of Solar - a great month of weather to start with.
755.7kWh generated.
For the second half of the month have been putting some 10kwh a day into a heater, after immersion is done. Daily Energy Used rose then.
Compared to the same period last year, when had oil boiler on morning and evening to heat water / rads, this year the boiler has not been turned on at all since March 15th.
Lads don't forget to update your stats in the google sheet

Afraid I've moved on to the website.
It's VIEW only mode. Where is it now ? Link ?
2.5 kwp system south facing ,Galway City.
Total for March was 314.6kwh.
Best day was the 18th with 16.2kwh.
Worst day was the 2nd with 1.6kwh.
March total was best since July last year and the second best month since install.
6.2kWp system, SE, Galway
March: 596.01kWh
Best day 28th - 29.33kwh
Worst day 2nd - 3.05kWh
Pretty good month, best month since July! 16 days with over 20kWh produced.
March on the 7.8kw of panels in Louth produced 874Kw.
Best day produced 44.1kw
