Yesterday we saw this phenomenon first hand. We have a pair of framed 180w panels on each port and starboard guardrail. So 2x180w each side. In addition, we have some nasty Renogy flexible panels that dont produce what they should but none the less, this set of 920w of solar did an instantaneous peak yesterday of 37A @24v!!
The sun was as close to overhead as it gets. The starboard 360w panels peaked at 448w. The portside peaked at 404w and the crappy Renogy 200w worth of flexi crap peaked at 127w. People talk about the benefits of MPPT over PWM but to actually see 448w peak on 360w panels is incredible. I just happened to be looking at the solar input at that time. Seeing 37A on the shunt was a bit of a shock! What was surprising was it wasn't that sunny. It was then that I realised it was the cloud edge effect. Fantastic but I am a bit of an anorak with these things
