Hard to believe that a week ago we had daytime temperatures of over 25 degrees, and that three days ago the solar panels served up over 8 kilowatts…

Despite a constant procession of fluffy clouds, our solar panels had their best day so far.

For some reason, despite identical conditions, the solar panels produced a bell-shaped output curve and another kilowatt.
No clouds today, but the output from the solar panels was only slightly higher than in the days of rolling cumulus and, as always, dipped sharply in the middle of the day. The reason: shadows from the chimney stack falling on small parts of one or two panels cause all the panels, wired in series, to react as if they are shaded as well. All for one and one for all; divided we stand, united we fall…

Trying to link the stuff in the sky to the wave-like output of the solar panels. This batch of fluffy summery clouds sprang up between two massive banks of nimbostratus so the day was duller than it looks.
