Renewables: "talking 'bout my generation"

Hawaii + 2.1.kWh today:D

July total = 471 kWh.....less than my worst July (2012) of 473kWh:(

Not enough to reach July PVGIS of 497 kWh

Made 2617 kWh so far this year so all is not bad:rotfl:

ANTIGUA !!!!! well, as I have absolutely NO idea what a "HUAWEI" is anyway, I thought I'd create my own title....

But my NEW installed 4KW system, turned on late Wed pm,
generated 12KW that day, 20 KW on Thursday (making 32 KW total),
and now today, Friday 31 July, another 21 KW, total is now 53KW.

Is that good, I ask ??? 16 Enhance XM panels, Solar Edge invertor, SW facing roof at 33 degree pitch, with tree shading issues - whaddya think,
Martin / Martyn ? ?

where am I - in The WE*T country, near Penzance...

Where did you pull that lot from.....????

Bit down on yesterday.. only a/an Hawaii + 0.72 O's..

Today 5.55 O's. Month 110.8% up on July PVGIS target. Seemed like a poor month but all ended well.

Gosh!! 6.25 O's today! That's a welcome result after what I thought was a rubbish month. 501 kWh for month, well above pvgis estimate of 460.:j:j:j

First month for me returning 539.1 kwh against a prediction of 431.33 kwh so very pleased so far with a 25% better yield than expected :j (And I thought the month was rubbish!)

Where are you......on the equator?:)

517kwh for my first month according to the inverter, 503 by the export meter; but I want to check the exact roof pitch and aspect to confirm my pvgis target. Any websites where I can check which way exactly my roof faces?

Cracking day, 6.72 'O's yesterday, 31st.
So exceeded prediction with 2 1/2 days missing.
But....
As I am not at home, I got my missus to take a photo of the generation meter.
Not sure what time she took the photo but it says 460.9kWh total so far, but SE this morning says 475.9kWh, so 15kWh discrepency between the two. I doubt that whatever time she took the photo that 15kWh could have been generated between.
Is this normal for there to be such a large discrepancy between the generation meter and the SE inverter?
This is over just under 1 month!

You could try looking at either Google maps or Google Earth and zoom down to show an aerial view of your house when by default N will be at top of map.


Or just use a compass ?


Or bang a stick in the ground and note what direction the shadow falls at True Noon (1pm if you live on the Greenwich meridian; up to 15mins later if you live in Cornwall etc) That line will be true North.

Hiya. That's about 3% over-read ..... hmmm. My SE inverter over-reads by about 1%. My SMA2500 under-reads by about 1%, and my SMA1200 under-reads by about 2.5% so they are all out compared to the TGMs.

But, the TGMs are just 'normal' import meters, which as import meters are allowed a tolerance of +1%/-2%, so could potentially be under-reading by 2%.
