The solar panel and the reflector are horizontal. Think of a trough 
reflector with a pipe in the middle. Now remove the pipe and put it on 
(almost) the ground. To make the trough illuminate it you have to tilt 
the trough down. It becomes almost vertical. It is also no longer the 
same shape (although the same shape will work fine for a simple trough 
collector). You can also make the trough much larger now, as it 
is shallower. 'Offset' sattelite dishes use the same idea.
