Quick update - I found an old satellite dish pole mount ("foot") on Ebay - and so far it works well. It just slips on a standard speaker tripod (the pole diameters were different, but some rubber pipe fittings and drilling a hole for a pin were easy fixed). 2 bolts allow it to tilt and lock into position - replaced those with wingnuts for tool-free adjustment. I have a simple unistrut frame bolted on the top of the foot.
I have (2) 100w panels that can quickly mount onto the superstrut - I drilled holes in the panel frame and used speed nuts - and use some 1.5" knob studs (again, tool-free in the field) to lock the panels onto the stand. Takes less than a minute to setup, allows me roughly 30 degrees of tilt (from flat/horizontal) and the tripod allows for easy rotation. I also made MC4 to Anderson SB75 adaptors - so I can quickly dis/connect in the field, tool-free. It let's me get the panels off the ground (roughly 6' of height and stable) - enough to overcome shading issues of people standing nearby and looks a bit more pro.
I mostly use this for a portable "solar generator" style setup, powering sound systems for small concerts, rallies, press conferences etc. 200w input on the panels, but a 3kw inverter (at 24v), and varying battery capacity depending on the day's needs. I may add a duplicate 200w panel/stand setup next.
