How is solar generation spread across the year?

Q: Approximately what is the increase in available light for generation of electricity in April to September compared to the winter months of October to March?
A: While I haven't been able to lay my hands on details of the available light I can illustrate the variations in generation that you will get over the year. The table below shows the predicted figures (which have proved pretty accurate) for my own solar installation in Devon. The figures are for a 2.1kWp array facing south east.
As you can see from the table above, March to the end of September account for the bulk of the solar generation, with only small amounts generated in the gloomy days of November to January.
