Interesting device!
I'm thinking right now of how I want to establish a ground array at Casa Westend. This would be about 15-20 modules and they should have adjustable tilt for seasonal differences in sun angle. Up here, at 45 latitude, we get a short day in Winter so getting the best harvest is critical.
FWIW, I installed a four way tilt for the single module on my TT roof. If I had to do it over, it would only tilt one or two ways as getting up there to adjust different tilt angle is troublesome. In storage, I set the tilt to about 60 degrees and it sits like that all Winter. When travelling the module lies flat.
I am considering adding another module or two and adding battery capacity. This would enable me to run a small 5K air conditioner for a few hours, when needed. An alternative, while on trips, is to just pull in a camp ground and use the available power. I just would rather park away from folks, my personal preference but not always possible.
