yeah and uh, idk if you noticed, generally more than one person lives in an apartment building, it's about as good as it's going to get unless you're installing solar from tax payer money, or utility company money.

While tracking might let you collect more energy, you also lose more of your balcony, and you’re back to making the install expensive and complicated. Not worth it

dont use tracking on a balcony??? Also not all tracking setups are expensive and complicated, the entire reason you would want to do them is to greatly increase the total amount of power production throughout the day, and you can very easily calculate the complexity cost, maintenance cost, and additional install cost over to the potential saved/produced value of the array post installation.

I mean if you're doing 2 axis tracking, sure it's probably more expensive, but one axis tracking is still reasonably effective, especially if you're in a decent spot and able to take advantage of it. The other option is installing more panels total, and when you're space limited, that's going to become a constraint.
