It would not be all that difficult to attach a panel to those racks.
But you say they are known to be weak. Ive had surfboard racks attached to factory racks that i did not trust at highway speeds. I would run an additional strap through the back doors over the boards for peace of mind at 85mph into a headwind on 2 lane road with semi trucks in the opposite lane.
I would enjoy actual data on how much more output panels make at various panel temperatures. Id then enjoy actual data as to how much cooler elevated panels are compared to those that hug the roof say if they fit between those racks as opposed to having to rest atop them.
My thoughts are if it is a few watts difference. Then lower closer to the roof panels would in many cases be more desirable, to some.
One thing to keep in mind is wind over a flat panel which is mounted on a curved surface. Like a transit roof will help evacuate more air than would a flat panel over a flat asphalt stick and brick roof.
Just not sure.elevating panels.for.more.cooling airflow.is.actually measurably beneficial in a vandwelling scenario.
If its 238 watts versus 241 more.elevated and conspicuous and adding more.wind drag, id choose 238. If it is 20 watts difference, that's significant but perhaps acceptable to the user.
