Nobody seems to have mentioned that insulation works both ways.  About a
month ago I was into a hive as the sun was going down on a cool evening.  I was
amazed how much heat there was inside the hive next to the sunny side compared
to the shaded.  Unless one is located very far beyond the Arctic Circle
(Northern Alaska or Scandinavia) there could be appreciable radiant heat warming the
hive from even a low sun when it shines, unless the insulation stops it.
