Not every roof allows for perfect southward angling (obviously).
And I'm obviously not saying that you should point panels north either. I'm disputing the parent commenter's claim that it would be beneficial to have all panels aimed directly due south. Because that way you get one strong peak at noon, which is the time of day when solar energy is most abundant but also least used.
