You can think of it as a solar thermal plant with the advantage that a good percentage of the power comes out directly in the form of electricity. A sort of "topping" regime combined cycle. >In my opinion, >the only real advantage to PV is that it has no moving parts: no >fluid, no tracking mirrors.
