The sun is never overhead beyond the tropic.

Explanation:
I suppose it is really. There is plenty of sunlight above and below the tropics.
What you really mean, is that you can never see the Sun directly overhead between the Poles and the two Tropics.
Over the year, if you live between the two tropics, there will be a time that the Sun is very close to being overhead, and in some cases, IS directly overhead, so that no object casts a shadow. ( Google Lahaina Noon )
All Globes you can buy are tilted on their stands, just as the Earth is in relation to the Sun. If you pretend that a nearby wall in you bedroom is the Sun, the part of the Globe closest to the wall changes as you turn the stand around. If you use a stick of about a metre, turn the stand around, and watch how the part of the earth closest to the wall moves from the tropic of Cancer to the tropic of Capricorn.
This is emulating the Earth's trip around the Sun every year. There will never be a time when the part of the Globe above or below the tropics is ever at right angles to the wall.
