CPV Exaggerated claims?

-> My contention is that because CPV requires 2 axis trackers the spacing

Can you back up your contention with calculations?

My guess is that it will depend on the latitude. Near the equator,
where the sun is high in the sky for much of the day, shadowing is
likely to be less of a problem than at high latitudes, where shadows
are always long.

True, but then near the equator, with the sun high in the sky, a simple flat
panel non-tracking collector would have a higher output as well.

So the question still remains, does the dual tracking version really buy you
that much more output than simple flat panels when talking a large land area
(multiple acres)?
