The Biggest EOC spikes I have Noticed are when there are the big puffy cumulous clouds passing by on a cooler day, and the cloud is moving away near solar noon.
The more prolonged spikes have been noticed when the marine layer is at the point of burning off above.
I see that some attribute these spikes to panel temperature alone, but if panel temperature alone could cause a 30% prolonged increase in output, then it would be worthwhile to devise a method to keep the panels cooler, and perhaps heat water at the same time. I believe it is a combo of effects and somehow the clouds are acting like a magnifying glass passing overhead, and the time one is in an area of cloud enhanced/ focused sunlight is usually very brief, But it is a worthwhile reason for having lots of overhead on a solar controller.
