I'm not too sure what this is showing - there are 2 colours of blue blocks and a yellow arc - is one of these power output, and why is it solid, and not a line, does this represent the short duration blackouts.
(Just found this one again - I do wish they wouldn't move things out of the Wiring Regs!)
So, what appliances did you have running at 1.00 pm to make use of the electricity generated?
Often just my baseload of various controls, gadgets, fridge etc. (typically 200-300W), sometimes the washing machine, but on a good day the majority is exported and so used by the neighbours (I'm paid generously for generating it after all).
and yes, i can see what you mean about the overshoot on a restart vs continuous, looks as if it could be as much as 10%.
Indeed. I was aware of the reduced efficiency with temperature but was surprised the effect was so large. The theory of just-out-of-line clouds redirecting a little extra light towards the panels makes a lot of sense too - so perhaps a combination of the two might explain the 10%(ish).
Thinking about it, the thermal effect should always lag the cloud passage, but the cloud diffusion effect would presumably happen just as much with an approaching cloud as with a departing one - so a peak should sometimes appear before a trough in that case. I'll look closer at the data to see if I can see any such effect….
Thanks all - it's been enlightening!

Monitoring solar generation and import/export generally needs a “smart” inverter with an internet connection. My Solax inverter sends reports to Solax every 10 minutes, so I can log on to the web site and see how it's doing, even if I'm not at home.
I believe it's also possible to retro-fit monitoring systems to an existing solar install, using clip-on current clamps on both the incoming live meter tail and the live from the inverter. I'm not sure if anybody still makes those.
