I go back and forth on the shade issue. I moved one hive into full sun last year in order to keep the ****roaches out and help with small hive beetles. Our temps and humidity in Georgia get a lot higher than in the Southwest, and so far that hive is doing well. I have to point out, though, that this hive has a special "attic" through which excess heat can be ventilated. The roof also has reflective insulation under the corrugation panels.
