Generation updates

You'll probably be pleased to hear that I'm well aware of the fact it could get very dull very quickly if I post updates for every single day's result. Seeing as I'm posting anyway, I'll post yesterday's total - wall to wall solid white cloud all day long meant it was the poorest result yet at 3.9kWh for the day.

For future updates, I'll go to a week-at-a-time, eventually dropping to month-at-a-time (as the novelty wears off).  I'm keeping the totals on a spreadsheet with some actual vs predicted comparisons, which I'll post as and when.
