My system managed 148kWh, making it the worst March since install - typically I get 200kWh with the best in 2014 being 238!

ImmerSUN did just 11kWh too but the PowerVault takes the Lion’s share these days

System: Ground mounted 3.84kWp, slope 40°, 15° east of south,, Lat 50° 40' West Dorset
12 months generation to the end of March 2018 was 3692.5 kWh (961.6 kWh/kWp)

Yet another record low generation figure for March and the first time that March’s generation was lower than that of the previous month even with its three fewer days. It was a dull wet month to put it mildly with the average March rainfall -  70.2mm -  being ‘bettered’ by over 2.5 times -181.8mm. Making it the wettest month for two and a half years and the wettest March since   records began here at the turn of the century.

Generation for the months of March:
2018 -  257.2 kWh
2017 -  266.7 kWh
2016 -  359.0 kWh
2015 -  332.0 kWh
2014 – 409.5 kWh
2013 – 275.1 kWh
2012 – 421.7 kWh

Mid-March Shading. Mornings to 08:00GMT. Afternoons from 16:00GMT
PVGIS: 299 kWh not taking shading into account.
PVGIS: 278 kWh taking shading into account.(7.0 % reduction)

Total generation: 257.2 kWh 92.5 % of PVGIS (shaded) prediction.
Generation per kWp: 67 kWh

Daily average
Predicted PVGIS (shaded): 9.0 kWh
Actual: 8.3 kWh
 Daily average per kWp: 2.2 kWh

Best Day: 19.3 kWh on 13th
Best day per kWp: 5.0 kWh

Worst Days: 0.9 kWh on 9th
Worst days per kWp: 0.2 kWh  (There were two days with zero and 0.1kWh when covered with snow) .
