Renewables: "talking 'bout my generation"

Record day here
7.82 Os

That might be the highest figure I've ever seen, personally I've never quite reached 7. What's the spec of your system and your location?

@KevinG I got 7.04 Os yesterday. I think 7.8 is the highest I've seen on here as well.

I have a 6.6kwh system and generated 46.5.

So jealous of the 7's and near 8!  6 O's is my max, and even then only just.

Lovely 5.98 O's yesterday. Month end projection 113%, but really hoping that the forecast of rain on Sun/Mon is correct.

6.6kW, I'm jealous. I could only fit 2kW on my roof at the time, could almost certainly fit 3kW+ now. My best ever day was 13 May 2019 with 6.79 Os but if June carries on like this I think it will be my best ever month.

6.2 Saturday, 6.4 Sunday. Rubbish Monday 2.6 and 6.6 Tuesday (yesterday) 👍

With only 2 days until that middle of June only at 38% of pvis prediction.

Let's hope the sun keeps shining.

Back on target for 720kwh for month end. 360 was the break even today think I'll finish on 380

Best day’s generation since June  2020  2021. I am on holiday so can’t see the generation meter but my MyEnergi app says 42.7 kWh and Solarman 42.3 kWh. I know my baseload usage is 4.2 kWh daily and Octopus Watch app (which sources from the smart meter) tells me my net export was 36.70 KWh (actual export 38.24 kWh and actual import 1.54kWh) so my best calculation is 40.9kWh generated. For anyone interested that’s 5.24 Os.

It would be nice to be able to rely on the inverter figures but they invariably come out higher than the generation meter. Any calculation I make for the two roofs independently can only come from the inverters and I have to apply a correction factor. I suppose everyone else is in the same position so which figure is everyone using?

Does anyone know why the inverter figures differ from the generation meter?

Edit: correction needed as checking back on my stats I actually achieved 41.25 kWh (from generation meter) on 2 June 2021.

The TGM has to comply with a standard;  The 'toy' meter within the inverter doesn't.

I'm quite lucky in that respect as in 42.664 MWh of generation (according to inverter) the TGM is only 42kWh more.  i.e inverter is probably reading 0.1% slow  although it's always possible that the TGM is allowed to read 0.1% above true which would make the inverter incredibly accurate.

Others have reported huge differences.

I’m pretty sure it isn’t the location that’s the key to that huge performance, although I’m not that far away and we did have our best day for 2 years. A near neighbour with a south facing roof only did 6.6 Os yesterday. Do you have Solar Edge?
