How are you planning to explain to your wife why she should drive a car with a
big-ass funnel strapped to the roof?
It’s not the _bottom_ of the funnel that’s roof-sized, it’s the _top_. The
bottom of the funnel is the PV receptors. Using a concentrator doesn’t
increase the amount of energy collected, because it doesn’t increase the area
of the roof. It decreases the size of the PV receptor needed, which allows for
different economies of production of the lens versus PV receptor. It doesn’t
make magic extra energy.
