Hi, there are definitely attemps for implementing small scale solarthermal  power plant, here some sources.

Small scale solar thermal energy - German government platform:

And here some articles and plactical applications:

i design 1KW solar thermal power plant during my Bachelor of electrical engineering final year project. i would say only problem i faced is availability of mini steam turbine or Stirling engine..
