move some of your engine load to solar. For example, your Electronic engine cooling and electronic AC power demands can be facilitated by solar. Your aerodynamic wind deflector above cab can be loaded up with cells as can the hood.

IMHO over the road trucks should be designed like Locomotives. The diesel engine is just a generator that keeps capacitors charged. Capacitors power the electric engine that drives the wheels. The actual trailer of goods being hauled sits inside a skin loaded with solar cells. Skin just clamps to each trailer after it is latched to the truck.

I wonder too if aerodynamics can be smoothed by passing turbulent air thru fins of wind generators that redirects air to a stable flow. This in effect capitalizes a bad thing (turbulence already is creating drag) and smooths it out while creating electricity. If one can get the drag of the wind generator to equal the former drag of the turbulent air... then net effect is no "additional" wind drag created by generators. A win win.
