Won't go into motorized system, no.
2 orientations will be problematic if they are mounted on a roof. But I can think about how I park the trailer, with in the limits of the property.
That is why I thought about angle adjustment. So at least the angle is as best I can get it.
.
Trailer could have array hinged at one side, tilted up for a better angle.
Second array at front edge of roof could tilt up as well. That would give two orientations 90 degrees apart.
One array could lie down partially covering the other for storage/transportation, for somewhat larger total.
How big the arrays and where located would influence what sun angles could cause them to shade each other, can't locate as ideally as on the ground without making smaller.
Array flat on roof (or slightly tilted), and arrays on side and rear that can tilt out? Those would avoid shading.
For my pickup truck roof I'm considering two arrays (or panels) hinged on left and right. They would fold flat, one covering the other. Tilted up 60 degrees forms equilateral triangle. It would never present more than the area of one panel to the sun, but should produce better from morning to evening, during the summer. It would require tilting to the front as well to be good other seasons.
What do you mean by "clipping production" ? If you don't mind me asking.
If available PV is within scc (or GT inverter) limit, power produced follows a curve.
If in the middle of the day it exceeds max for scc, output is "clipped" at what scc can process.
I'm going to look up what you mean by this second part...
If you have a 100 Ah battery that can accept up to 0.5C, 50A charge rate at moderate temperature,
and enough PV to produce 50A (or even more),
50A charge is OK only if battery temperature doesn't get too cold (or too hot).
Mostly we've seen specs for minimum and maximum temperature at which it can be charged, e.g. not below freezing, 0 degrees C.
But some sources indicated at 5 or 10 degrees C, only a reduced charge rate was OK, higher charge would degrade battery.
Maybe 0.15C, 15A, would be OK all the way down to 10 degrees C.
If you had an all-in-one with PV MPPT input, battery connection, and inverter output, it could be programmed for 15A charge current.
But with 50A available from PV, it could use the other 35A to feed inverter when you have AC loads. Adjust harvested power so battery charge remains at 15A.
Victron equipment includes scc that can be commanded by data bus. With a battery shunt, charge current can be measured. One more monitor device (Cerbo?) can read the shunt and control scc, so extra power is collected for loads like inverter, but battery charge current is regulated.
My system is AC coupled (GT PV inverters plus battery inverter/charger). I've programmed it for 0.2C (80A into 400 Ah AGM battery) but PV inverters can deliver much more. While on-grid they backfeed for net metering. When grid is down, their output is adjusted to supply AC loads plus enough for battery charging.
