Fresnel Solar Future?

 

Fresnel solar experiment at PSA, Almeria

What thin film is to PV,  Fresnel is to solar thermal- less efficient but also a lot cheaper than parabolics.  Fresnel requires less solar concentration, (and precision technology), less land than parabolics (half the 19m2 separation to avoid shade), and can withstand wind.  We learned at the experimental platform PSA that Fresnel may be making a comeback in southern Spain.  Novatec Biosol’s plant in Murcia is operational today.  It’s an example of an unambitious technology offering good returns.
