I have bought the panels
and slides. They look good.
Next up I need to finalize the design.
Two things I am considering:
1. The flat bar that runs top to bottom on the solar panel frame and bolts to the rail clamp- I might make it run side to side instead. It would be a longer beam but would then tie into the angle iron and take the lower panels
frame out of the load path to the second, extended panel.
2. I have drawn the assembly up with the aluminum
as the material in mind for the angle iron, flat bar, and gussets. I might also consider smaller sections of stainless instead. A considerations is galvanic corrosion
and where is it easiest to insulate the two. Another consideration would be strength to weight and I believe stainless wins in strength over density, but maybe not when moment of inertia comes into play.
And finally, one thought I had on the rotational support.. Something like a telescoping pole will slip if the load gets out of control, and that might mean the panels are saved.
