Yeah you're right. But, tracking solar (and solar with fixed positioning that maximises energy output later in the day) largely applies for more sophisticated sites such as commercial and industrial. I've seen such setups that forego around 20% of solar energy production to maximise production during more expensive time of use windows (including offsetting time of use demand charges).

Residential installations are usually setup to maximise the total output, and often the positioning is constrained by the geometry of the roof. Residential solar installers are really in a race to the bottom.

One up and coming trend which might have a significant impact on this is for residential retail tariffs to be directly linked, at 30min resolution, to the wholesale energy market prices.
