How to mount solar panels thin plywood bighorn roof

Thanks for the input guys. I'll probably go with something along the lines of the aluminum L channel between the studs. With the roof decking only being 3/8th inch plywood I'm not sure the bracket screws would hold going down the freeway. Historically we average about 7,000 miles a year towing, but with retirement coming up very shortly we're hoping to get a little more in. The road miles seem to be what tears up our rigs over the years.
