Solar Fotovoltaica VS Solar Termica a Gran Escala (Ingles)

The Cost of Utility-scale Solar: PV vs. CST: "by Mike Taylor, Solar Electric Power Association

Q: On a utility scale, which of these two technologies is cheaper: photovoltaics (PV) or concentrating solar thermal (CST)? -- Lisa B, Denver, Colorado
A:

The short answer would be that on an apples-to-apples comparison in the southwestern United States, concentrating solar thermal parabolic troughs (CST) have a lower levelized cost of energy (LCOE) per kilowatt-hour (kWh) than photovoltaics (PV) today. Outside of the broad southwest (which includes 7-8 states), PV is really the only game in town (at least for now, a CST project in Florida not-withstanding).

Looking forward, PV probably has a faster cost reduction curve than CST and their LCOE will cross paths within the next five years, i.e. PV will become cheaper. Concentrating photovoltaics (CPV) is the wild card that could also reach parity with CST over the next ten years."
