Does that concentration unit cool the PV cell(s)? Heat is the enemy of efficiency. There is an Israeli company makes this sort of collector - it uses the heat gathered, and cooling the PV keeps as much of the added efficiency as possible.

The thing is though, it all comes down to how much of the sun's energy you can gather - and that comes from the area the sunlight shines on.
