I have 2 arrays, 9 panels each, all same brand/model of 250w panel. Panels in each array are all oriented the same and are laid out similarly, 5 panels on the bottom row, 4 panels on the top row a little over a panels height further up the roof.
All with Tigo TS4-R-O optimisers on them. No cloud connect etc though so I do not have panel level monitoring.
My understanding was optimisers will allow as much power from unshaded panels as possible when some of the others are shaded?
In one array, I noticed power dropped off sharply today and asked my wife at home to take a look at the panels and send me a photo. 5 panels in full shade, leaving 4 exposed to almost full sun, yet that particular array was only producing under 200w, when it appeared 4 of the panels had plenty of sun.
I appear to be seeing increased production from the system on both arrays in general (for winter as I have shading issues during winter specifically when the sun is lower), but I was under the impression that I could effectively have say 8 of 9 panels shaded and still see decent output from the 1 remaining panel (extreme example)
Is there a limit to how many panels you can have shaded when all are fitted with optimisers or is this indicating I have a bad optimiser/other issue?
