Where did you get your morning shade fixation from?

They don't build them in deserts that far north, do they?
I got this "fixation" by doing the math to figure out why panels do so badly when there's still seven and a half hours of daylight.
The insolation per square meter of ground is very low when the sun is near the horizon. But the insolation of a flat surface at 60 degrees of tilt is still pretty good. If you avoid shade.
Please tell me you have no disagreements with that. It's basic math.
So as you said with basic panels "one cell being shaded criples the output of the entire row". Normal commercial installs don't try to capture the morning sun. But in the middle of winter in Denmark the "morning" sun is basically all you have access to.
You said "They don't care about shade when the sun is low because when the sun is low the incidence angle is terrible in the first place."
If you tilt really far and avoid shade, you counteract the bad incidence angle. A single square meter of panel can absorb the light that would have hit 6 square meters of ground.
