Super result for Jan, I have to assume very little shading given that generation

ECO_Mental

Jan 2024 a good enough start at 313kWh on my 6.1 kWp system in Cork.

It was well over the estimate and good bit better than last Jan. Those cold clear days were what drove it

Used 49% of it but Im not concerned too much about that with the FIT rates being good. Graphs below are the last 2 years and the daliy PV production.

152kwh for February on a 4kwp system in south Dublin city, installed mid January. South east facing. Shy 20kwh of PVGIS prediction.

cython

193ish kWh here on a 4.86 kW system for February, split on south (hip) and west faces of roof. Located in Dublin 15. Significant improvement on the ~105 kWh from January, thankfully.

203 kw 2024

175 kw 2023

Not sure about 10 days as i lost data due to broadband issues

8.88 split e/w

1.68 south

Today 14.5 and 4 of that came from diy setup 😎👌 ☀️☀️

allinthehead

New 5.95kwp rooftop array installed on the 17/02 produced 176kwh

Existing 4.8kwp garden array produced 145.5kwh

Total 321.5kwh.

Export 81kwh

Import 609kwh

Delighted with the performance of the new array, 7.4kwh produced today before the garden array had produced 1kwh due to shading.

That's excellent on the new array whoop whoop

426 kwh Generated in February 2024

147kwh Feb this year

145kwh Feb 2023.

ColemanY2K

319kWh in february.

that's a disappointing 84kWh shy of the PVGIS estimate of 403kWh. 8 of the first 10 days of february were shocking which could explain it.

however the power produced which we consumed plus FIT contributed to reducing the electricity bill by half in our all electric house.

super_dad

185 kWh produced from a 4.1 kwp south facing roof mounted array . Best day since beginning of Oct was 26/2/24, with 16.2 kWh produced. County Donegal

bullit_dodger

Start of the month was pretty meh, but a strong finish.

Just managed to scrap over PVGIS, but that was really due to the bonus day we got this year due to the leap year and it being a pretty decent day here in Dublin today. The 10% better than last year is good/bad. Good that I beat last year, but I'd have expected to beat it by more as I've 3x extra panels this year, which is 19% more Kwp.

Still overall happy with this as "winter is finished" for me :-)

curioustony

Best February day 26th since records began. The 29th pushed it over 2022 too.

Almost 3 years in now

The use buy mix is coming out of winter mode

Almost finished with shading too

Finally, in real money, still on track for net zero this year

With a small reduction coming from next month

Bif

301kwh from 6.9 kWp sSouth facing for Feb 2024. Down from 324 for Feb 2023

Mr Q

227kWh from 8kW split evenly over East/West at about 15 degrees. Up from 122kWh in January.

Expect to come close to double the February output in March and close to 5 times it in May.

The E/W layout is very poor for me over the winter.
