My assumption was if 1/3 of half-cut panel was shaded then its output will go down by 1/6 only. However, as per this video that's actually not what happens:

I have a scenario where the bottom third (in landscape orientation) of the panel would be shaded during winter season. After watching the above video, I'm wondering when the panel is in portrait mode, then entire lower half would be bypassed and panel will be working at half-output (so entire string would be at half output, right?) But if I place the panel in landscape orientation. Then lower 1/3 of both halves would be bypassed and the panel would effectively generate 2/3 so string would be at 2/3 output as well. Is that correct?
