We live in Southern Arizona.
The A/C unit is on the south side of the house.

In the summer time, you could fry eggs on the A/C housing.

Is there any advantage to erecting some sort of shade
over the A/C unit ?

Enough to where the ( energy ) savings would be significant ?

I've never heard of a single scientific study that showed that
shading would reduce energy usage significantly.

The ambient conditions are essentially overwhelmed by the energy
required to run the compressor.

If you live in a cave and use solar powered electric compressor to
drive a 1 ton ac, then maybe it would make a slight difference.
