The predicted output was 210 kWh using SAP calculations and 243 kWh using PV-GIS so the actual output of 314kWh was over 50% higher than the SAP2009 estimate. This number is slightly higher than the number shown on the website link below as our inverter reads slightly lower than the generation meter.
Our solar PV installation consists of 14 x 235W Sungrid panels with Sunny Boy 3000HF inverter.
It will be interesting to see how this pattern continues over the rest of the year. The South East of England is currently suffering a drought so further sunny days may be good for Solar PV but not for water resources. I guess the ideal weather is sunshine during daylight and rain overnight.

This compares the peak generation, maximum daily output and times that the panels were generating electricity by month.
