 My September effort…
Out of 88 Hours of Sun & 75mm of Rain My Kit managed this;

Total generation: 293 kWh.
                  
259 kWh Jun 2016,
343 kWh Jun 2015,
320 kWh Jun 2014,
288 kWh Jun 2013,
336 kWh Jun 2012,    Avg to Date=306 kWh so  Sad

PVGIS (classic)   270 kWh = 108%
PVGIS (cmsaf)    292 kWh = 100%

Daily average:  9.76 kWh

Generation per kWp: 83.7 kWh

Daily average per kWp: 2.79 kWh

Best day:      17.67 kWh – 13th

Worst day:     2.44 kWh – 25th

Capacity  Orientation  Slope   Lat     Total     Best       Worst     PVGIS(c)    %PVGIS    kWh/kWp    Daily/kWp   Days    
3.5            225           35      51.3    293       17.67     2.44       270             108         83.7          2.79          30

According to a British Gas Energy monitor (freebie so accuracy doubtful!)  in the last 30 days 138 kWh has been sent to immersions!
138kWh = 47% of the 293kWh Generated so 53% not sent to immersions ( Exported!)  I know not really.
