Three Plays on Solar Strength This Summer

I just don't get the interest in thinfilms like FSLR and ENER. Their solar efficiencies are less than half that of SPWR or STP. Solar panels are less than half the cost of a solar system. For a solar system of a given energy output the thinfilms require twice as much of all this other stuff; land, labor, concrete or roof, wire, inverters, junction boxes, maintenance, ... I am putting my investments on the solid crystalline manufacturers.
