What is Annual UK Solar Panel Output from Domestic Installation?

What is the UK Solar Panel Output per year?

We have now had our solar panels for over 12 months so are starting to get year on year comparisons of the output.

Our first year we generated 3095 kWh of electricity from our 3kWp panels (14x Sungrid 245W) but this would have been around 3250 kWh without a loss of 2 weeks generation in August 2012. This is substantially above the SAP2009 estimate of 2479kWh for a 3kWp system.

You can see this graph of Solar Panel Output in the UK which shows the peak at the middle of the day and how the output from solar panels drops towards the end of the day.
