Hi Ken,

We normally prioritize locations that are good for beekeepers: vehicle access for heavy materials, away from people (especially kids and pets), workable area, etc. 

Traditional advice suggests that sunny locations are better than shady locations, but I've kept plenty of healthy, productive colonies in shady locations.

I do suggest not keeping bees in a low area where moisture accumulates (like a depression) because bees can have difficulty managing the moisture.
