Unless the design has some sort of fairings, the drag will negate any down
force from the 'wing'
Depending on the trailer...think a better place for the solar array would be
flat mounted on top of the trailer
Am not up on the current inverters (mine were good to 10,000 hp) and always
amazed at how stuff has gotten so good
Better flat mounted because your travel direction varies from moment to moment
So an angled array might be facing the wrong direction and betcha when you
want them charging as much as they can
A flat mounted array will not be as efficient when the 'wing' mounted is
facing the right or best way, but would have better over all angles to the Sun
Also think flat mounted on the trailer would have less drag than on the TV
