The Highs and Lows of a year of Solar

Yesterday (20th April 2013) we surpassed all expectations and managed the best solar day since we had them installed, so it got me wondering about which days were good and bad. Having done the maths, I thought I'd put a table up:

And while we are at it, my last post did not account for the FIT payment so this is what we got from March 2012-March 2013 (about 5 days more than the year) = £609.50 total for 4 quarters for a total 2650 units generated.
