73.29 kWh total
2.36 kWh per day

Grid use = 2.61 kWh per day

Last year's grid-only use for May = 4.7 kWh per day

4.97 - 4.70 = 270 Wh per day battery/ system losses = 10% (ish) of generated stored power.

Still no big battery yet.  Sad

We also ended up with our best ever month, though the difference between the best may and the worst is not very much, were at least consistent here. But have to be happy with that.

Good Morning All,

Well, like Fintray, we have had another good month up here in Aberdeenshire land.

May total for the ROO/ FIT and FIT installation is 518.2kWHr and the 'extra' 1.675kW of panels (coupled with the Growatt) has delivered a further 127.7kWhr making a grand total of 645.9kWHr.

Things to be noted (possibly of interest to others):-

1. The amount of power coming from the 'extra' panels as an overall percentage has visibly improved as they have been moved to the steading roof from being propped up against the wall thereof. We're up from circa 19% contribution to 26% now although this is also biased by the Growatt contribution. Currently 5 of the 7 panels are on the roof. The Growatt battery isn't charging up to its full potential so I need to address this at some point.

2. Overall 'internal' utilisation of power produced has decreased from 77.2% to 66.2%. As detailed elsewhere this figure will deteriorate still further once the solar ET is 'fixed' (now scheduled for next week). I have no fundamental issue with exporting power but if sensible usage can be made on site then it will.

Regards

Richard

2nd best month ever. May 2011 was 2KWh better, system was then brand new.
Last three days of mist and overcast weather from the North Sea prevented a new record.

Best May since install in 2010, 3rd best month (Best June 2017 at 574kWh [190kWh/kWpk])

Might have been more but we had 5 power outages, one was for 5 hours on a nice sunny day and another for several hours in the morning, so total figure could have been around 20kWh higher.

My May effort…
Out of 174.2 Hours* of Sun & 45.6mm* of Rain My Kit managed this;

Total generation: 462 kWh! not the best May ever but above average!

433 kWh May 2017,                  
471 kWh May 2016,
449 kWh May 2015,
416 kWh May 2014,
434 kWh May 2013,
450 kWh May 2012,    Avg to Date= 457 kWh

PVGIS (classic)  396   kWh = 116%
PVGIS (cmsaf)   409   kWh = 113%

Daily average:  14.9 kWh

Generation per kWp: 132 kWh

Daily average per kWp: 4.25 kWh

Best day:   23.3  kWh – 14th

Worst day:  3.1  kWh – 30th  

Capacity  Orientation  Slope   Lat  Total  Best  Worst  PVGIS(c)  %PVGIS  kWh/kWp   Daily/kWp  Days    
3.5              225          35    51.3  462   23.3    3.1     396           116        132           4.25       31

According to a British Gas Energy monitor (freebie so accuracy doubtful!)  in the last 30 days 201 kWh has been sent to immersions!
201kWh = 43% of the 462 kWh Generated so 57% not sent to immersions ( Exported!)  I know not really.
