sun and rain

You might expect the amount of solar power we generate to increase over April, May, June (we are in the northern hemisphere).  That happened last year.  This year was a bit different.

The average power generated decreased month on month!  (Although, to be fair, the difference isn't very significant.)  Yes despite June having a lower average this year, it also had the sunniest day so far.

This average reduction wasn’t due to rain: May and June 2015 were the driest since (our) records began:

Ironically, as I sit writing this post, it is raining quite heavily…
