roof rack for solar
Since I'm committed to 12 volt because of a pure sine wave inverter, if I upgrade I will go MPPT with the Magnum PT-100. That would allow me to install 1200 watts of solar. To do that would require a ...

A/C is what - 1ft above the roof? If you raise the entire 1200W one foot above the roof, this is scary.
I would put a single small panel directly over the A/C, approximately the footprint of the shroud (2x3ft?) with very little clearance 0.5-0.75" from frame to shroud. And cover the rest of the roof with whatever fits in there, with some shading. Small A/C panel would likely be 12V, so you'll have to include another 12V with similar parameters, in series, - and the rest of array can be 24V.
I realize that the only way to avoid the shading completely is to raise the entire 1200W array above the A/C, but - man, this is scary.
