I stopped reading as soon as I got to the word "tracking". Solar panels are so cheap it's always better to overpanel than add tracking. Then I re-read a bit and this is about adding solar panels in space constrained areas. Why would you do that? I guess maybe if some company needs to virtue signal rather than actually use the power and has a small lawn. Solar is amazing, but don't try and jam it into places it doesn't make sense.

If the mounts are not too expensive it could make financial sense to even out the curve in the mornings and afternoons, especially as more and more solar comes online the price you get for your power will be higher if generation is offset from most other solar farms.

Many (most?) grid scale PV plants use at least single axis tracking. Sure adding more panels could also increase output, but these plants are usually completed covered with panels and there is no more space to add more.

If you don't have space for more panels, tracking can get you more output for more hours of the day.
