Here too, March has surpassed January and February combined.Hi All
Well, quite an interesting point .... today we passed the threshold where one month's (March's) generation exceeds that of the previous 3 months combined .... :cool:
... it's a first for us - wonder if it'll ever happen again ...

System 1 produced 104kWh in Jan, 151kWh in Feb and 275kWh in March so far.
System 2 produced 92kWh in Jan, 133 kWh in Feb and 254kWh in March so far.
The last few days have seen System 2 catching up with System 1 as the panel angles become more favourable and the shading in the afternoon reduces as the angle of the sun increases.

329.6kWh this month with one day to go, against a PVGIS classic estimate of 256kWh (+29%). We're not going to beat March 2012 though which clocked up 365.1kWh (+43%).
Forecast doesn't look too great for tomorrow though.Cider Country Solar PV generator: 3.7kWp Enfinity system on unshaded SE (-36deg azimuth) & 45deg roof0 -

HiI just checked ours and we're nowhere near. Did you have some bad months over winter?
Last 3 months for us were 417kWh (Dec 103,Jan 121,Feb 193) and March was 328kWh

Previous months weren't particularly bad. Generation was over PVGIS4 prediction in both Dec & Jan, followed by a pretty impressive Feb with March being well up on March 2012 ....

I'd say that comparing the current month to the previous 3 would be taken as being March14 vs (Dec13+Jan14+Feb14) ....

It would be jolly difficult to get a March figure that was greater than the total of Jan + Feb + March ! Unless of course Jan & Feb were both negative.NE Derbyshire.4kWp S Facing 17.5deg slope (dormer roof).24kWh of Pylontech batteries with Lux controller BEV : Hyundai Ioniq50 -

Similar boat here, but almost expected. Dec + Jan + Feb targets total 344kWh, with March's target being 340kWh.
Actual results for last 4 months (estimating today as average) I have 337.5kWh v's 377.2kWh.
Previous year (2012-13) was 323.9 v's 283.9 so an improvement all round this year.
My shallow off-south panels really kick-in in March.
Mart.Mart. Cardiff. 8.72 kWp PV systems (2.12 SSW 4.6 ESE & 2.0 WNW). 28kWh battery storage. Two A2A units for cleaner heating. Two BEV's for cleaner driving.

. Should have read the post more than once before going off to look at my figures. System 1 produced 92kWh in Dec and System 2 produced 79kWh. So therefore March was not as good as the previous 3 months combined. 347 cf 275 and 304 cf 254.
