Sunshine Percentage Map

Ran into this on Twitter today.  It's a good general comparison of sunlight percentage values for Michigan, and could probably be adjusted slightly for areas with more or less average natural sun, like the southwest and such.  I admit this only works in Michigan, but I'm sure you guys could find a use for it in other places with just a little adjusting.  If nothing else this design is useful for the new installer (or even a seasoned one) as it provides at a glance information.
