A solid month.
7.79kW south facing array, all electric house, no battery or EV.
West Waterford
Taken in isolation the net cost of imported electricity for the month is €133. It would have been circa. €180 without solar.

Excellent start to the year. More please. 6.5Kwp in South Dublin City.
Nearly 14% above PVGIS - we'll take that, and out of the dark months of Winter (Dec & Jan) - which are bleak. Even got a few kwh exported as I was away on holliers towards the end of the month. Bonus.
Those of us with E/W splits see a huge uptake now over the next 4-6 weeks. Roll on…

Barring the last few days, Feb was a bit disappointing….6.5kwp split exactly E/W in South Dublin city.
Only 92% of PVGIS and 13% down on last year (although last year we did have the extra day of course with it being a leap year) You can clearly see the lack of sunshine for 10-11 days there mid month.
On the plus side, winter is over as far as I'm concerned as my max production is back into the double digits from now until end of Oct/start of Nov. PVGIS for me for March is 290kWh so it ramps up a lot now……1 -

It's difficult to compare this Feb with previous as I added 58% more panels on the 14th. Inverter is now pretty much at its limit, as is the front roof. Also lost data for the 13/14. My bad. Two crap days tho. Inverter was also changed under warranty.
Here goes anyway
In real money, pinergy wins this month. I've also started charging a car, so it will be interesting to see how this works over time. Amazing how much electricity it takes too move a vehicle.
The newer inverter also give me access via HA to data without the cloud in near real-time
So that's a nice bonus too.

This is my fourth Feb with PV and its was on par with the best over the past few years at 362 kWh
Nearly hit 30 kWh on two days during the last week or so in Feb, middle of the month was a disaster though..
Roll on March
6.1kWp south facing, South of Cork City

Had a poor month as my system was offline for 10 days due to a ground fault. Fortunately it rectified itself after I disconnected the ground array for a few days. I suspect the deluge of rain that fell in the middle of the month was the reason.

just hit 1 year with the panels so here's my annual report
15 panels (7 east, 8 west) in north Wicklow, 6.45kWp total. 5kW/h battery.
I used to predict generation when I was researching the system and it predicted 4637kWh, well below what was actually produced (MySolar's quote predicted similar). However Ecoplex's report before they did the installation predicted 5430kWh which is fairly close to reality, I'm not sure why theirs was more accurate but I guess it took the particulars of the system into account.
