You're right on motorized trackers though, way too complex and expensive to make sense for most people
Yup, that's what I was referring to as a tilting mount in the original comment, a pivot and tracks to tilt the panels up/down to set them at whatever's optimal for your latitude and time period, or completely vertical if you're in a snow-heavy region.
The necessary engineering might not be worth it anyway, given current panel prices, unless space is a bit of a premium.
Depending on your local climate, that has to be sun and rain proof. (Most Nema 7 "3D printer" motors are not waterproof... Ask me now I know )
Nothing a quick hack job can't solve for you, but if you want to sell it (and make sure your customers will be satisfied for decades) it quickly adds up in price.
The panels can be stayed in their correct positions by a trash tire or whatever buried in the ground with two chains poking out to clip to the panel corner.
None of this is rocket science. This is all stuff that has been proven out over the past 200yr of fence and gate construction.
Similar could be used for changing between tilted and vertical though you'd need more material.
