I'm working on an outside place for my yellow bellied slider and the best location would not get direct sunlight.
It's outdoors, facing south (in Europe), but it's covered by an overhang and has some trees in front of it, so the sun never directly shines on it.
I don't know if this setup would be healthy enough for my turtle.
Turtles need to get dry once per day. They only take a sun bath at secure points. This means points, where they have the possibility to fall/drop into (almost deep) water to hide from predators. This is not the cause, if the sunspot is far from the water, so training therefor would be difficult until not possible.
The sun place should warm up to approximatly 40°C, without direct sunlight this is difficult.
Maybe you see the possibility to use mirror like surfaces to bring the sunlight to your turtle, like virolino suggests?
(Side note: turtles are very good in climbing. Please do not use mesh wire as boundaries around the outdoor enclosure.)
