Yes, but in the meantime the low PV panel costs should make it more effective to simply invest the material/cost of complicated frames with two axes and motors in more panels.

@infobeautiful true story, my house has fixed solar panels at a sub-optimal angle because the sunward-side of our roof had much more tree cover (and screw cutting down trees to generate energy, that's horrible). my future energy hack goal is to mount sun-tracking mirrors. keep the panels simple, let cheaper hardware do the complex work

@infobeautiful in theory great, but then each panel has to have its own motor etc, which will require more maintenance etc.

It would be nice to see a proper study with costs of the extra infrastructure, how much parasitic power is needed, and how much extra maintenance is required.

@infobeautiful Would a dome-like ensemble of small panels, like a [compound eye](https://en.wikipedia.org/wiki/Compound_eye) be more efficient than a moveable flat panel?
