Yeah, I thought mine was broken when the 1st winter hit :) E/W suffers in winter. And my W is actually NW so it goes to sleep until around about now from late Sept. 

Eye

As expected Jan & Feb were very poor (very bad shading) but there are signs of hope. Sun is getting higher and suspect in the next few weeks should get fully above the trees behind the house meaning April onwards we should be back in business and might get closer to the PVGIS predictions.

Pinergy's export rate is 25c unless you have a special rate with them. VAT isn't added to the rate

allinthehead

682kwh for March. Delighted with the new array. Haven't used the stove since February 16th, mostly electric heating since then.

tommythecat

231kwh produced. 97kwh sold back to the grid. Not too bad. Hopefully things improve over the coming months.

ColemanY2K

442 kWh produced

295 kWh exported

All electric house, the bill for the month has come to €56.41

while i'm happy the bill is small PVGIS on the other hand had estimated March production to be 620 kWh so a significant undershoot. i suspect it could be to do with a shady issue i have with an esb pole which would take 6 or more optimisers to resolve but only comes into play after 4pm. not sure if its the issue or if it is if its worth paying hundreds of euro to resolve.

I dunno I'd be more inclined to think we just had an extremely bad start to March that PVGIS hadn't estimated for.

This march was woeful. Look at any farming news sites, loads still have stock in because ground can't travel. Very little planting done too - and the weather has been that bad, there has been no " maybe" days

Worse than last march which was also bad

Panrich

451KWh from a 6.46KWp system. SSW facing Meath.

con747

It also depends where you are, I'm only down 6.5% on last year in the midlands.

Ha Long Bay

388 kWh for March and just a word of thanks for the boards poster for this site to be able to track production. This is from a 7.2 kWh system installed mid February 2022.

Exactly, I'm up 10% on last March. East Cork.

micks_address

February and March totals… 7.2kwp split 4/3 south east/north west.

dclifford

Installed 6th of March. Not sure what to make of it all.

2 PHEVs, AtoW heatpump and work from home 4 days a week

bullit_dodger

As others have posted, I'm also down on expected PVGIS, but this is down to the fact that March this year was pretty woeful barring the last 4-5 days. March is usually decent enough. Long time posters still speak in hushed tones of the fabled March 2022 - will we see it's like again? :-)

While I'm "up" on last year by 14%, end of March last year I added 3 new panels (Kwp increased 19%) so in real terms I'm down year-on-year as well as failing to make PVGIS by 7-8%.

If it wasn't for the last 5 days I'd have been well off. Also, I looked at the curves of solar production, and so far this year, there's not been 1 full day of solid sunshine. I mean two days in March were sub 1Kwhr!! That's pretty bad for March. Lots of days of it having a nice smooth curve until about lunchtime, and then the clouds roll in from the Dublin mountains and lurk about like a bad smell.

Sadly tomorrow Apr 1st is going to be crap also - and no that's not a April fools joke. My forecast algorithm has me generating ~3Kwhr. Surely it can't be that low?!

super_dad

286 kWh produced from a 4.1kwp roof mounted direct south facing array in Donegal. Installer prediction was 300.

curioustony

A full 3 calendar years on this journey now, with a total yield of 12,395.10 kWh

Crappy March, but the last few days helped it to just pip last year. Not a patch on '22.

PV & feed going in the correct direction, and the expensive buy is being squeezed.

There were a couple of days where the net cost was negative. Bit frustrating my inverter does not allow me to dump before the cheap rate.

There was a couple of days where the Pinergy cooline plan was cheaper, on the whole for me (battery size, and discharge to grid challenge), I'm still on the correct plan. May should see the credit increase.

keno-daytrader

421kWh for march 24. Really bad start to March, but slowly improved.

PVGIS predicted 440kWh surprised we came this close as it was looking horrible until the last week.

THE ALM

March was looking very poor but thankfully the last week has pulled things up a bit.

South Roscommon, 8.16Kwp, facing 210° at 35°, 9.6kWh battery

Total generation 552.6kWh (prediction at 591kWh, last year 569.30kWh)

Energy from Grid 855kWh

Exported to Grid 362kWh

To the Battery 188.8kWh

From the Battery 178.50kWh

Best day 30th with 39.30kWh

Worst day 9th with 3.9kWh

Energy exported would have generated €86.88 at Energia FIT rate.

Have a new array facing 120° at about 25° angle connected for the last few days and should have full monitoring set up for April. According to the myenergi app we generated 588kWh in total so the new array accounted for 35kWh since going live.

Total Exported: 316.68 kWh ( I expect the ESBN report to be a little lower)

All in all I'm expecting my bill for the month to be ~€25 in credit.
