Because the Sun "moves" more than that - any given angle of mirror would be completely out of sunshine for 
part of the day, and at unfavourable angles for a lot of the time.  Unless you have them horizontal, facing 
upwards, in which case you can't focus them, and you'd need a large clear area around them to make 
low-Sun-angles usable.

I'm not clear whether you are talking about trading efficiency for ease of construction?
