Any reason NOT to mount solar controller horizontally?

As long as the box you put it in is well ventilated it's probably fine in either mounting position.

Agreed. Mine is double sided taped to the top of the fuse box under the hood near enough to the grill/ headlight where air can flow in. So far all good
