Don't know nuttin' about nuttin' about PV gizmology and can't help you on
the leasing companies ... but I do remember my neighbour, a theoretical
physicist at the (Canadian) NRC, telling me about the Fresnel
lenses-based concentrated PV systems that he had been playing with where
PV cells the size of one's fingernail could replace the much larger PV
arrays one typically sees around the neighbourhood.
If available roof-top mounting area is a limiting factor (as seems to be
CV's case) then it would seem that the Fresnel lenses concentrators might
be useful .
Also, I do know that tracking systems seem to increase a system's
performance by about 30-40% (or more) in my neighbourhood (when comparing
the production of two identical sized 52 panel arrays within a few
concession roads of each other).
But as to which approach would provide the biggest bang for the buck, I
haven't a clue but my my wild-@$$ guess would be the Fresnel lens
concentrators simply because fewer PV cells would be required and Fresnel
lenses should be fairly cheap.
