The economics changed, it is now cheaper to put more panels East/West than having tracking ones as the tracking hardware is expensive. The tracking panels have the advantage to be put vertically in case of heavy hail.

Depends on what you mean by advantageous. Solar tracking setups are very expensive relative to a fixed panel one. They can produce more power per square meter via higher utilization but cost so much it makes more sense to just buy more panels if you have the space.

I meant advantageous in that the anti-duck-curve of these panels would only be superior compared to the duck curve of a fixed panel. But that it would be inferior compared to the (what I presume is) the very high peak of the regular-duck-curve of a traditional solar tracking panel, since the "tails" of the curve should be similar at sunrise/sunset. But I see now that solar tracking seems to have fallen out of favor due to the economics of how cheap panels are.

Absolutely but tracking is expensive relative to just throwing more panels at the problem.

But shading is also a factor. If you want to get unobstructed sun across the whole day, you need to be built on a nice curve of a hill? Or build just a straight line of panels?
