  • a solar field is a modular distributed system of solar col ⁇ lector assemblies (SCA) connected to each other via a system of pipes.
  • SCA solar col ⁇ lector assemblies
  • Each SCA is an independent unit for collection and for trans ⁇ fer of energy, with its own power to rotate and to communicate within an electronic network.
  • the SCA is a linear parabolic focusing collector with one di- mensional (usually East-West) tracking system.
  • Solar radia ⁇ tion is focused onto a heat collection element consisting of a hollow tube through which a heat transfer fluid is circulated .
  • the solar field comprises loops, which are for instance as ⁇ Sild from two SCAs .
  • Each SCA comprises for instance 8 pa ⁇ rabola segments.
  • the truss has two main functions: It supports parabolic reflectors of the SCA and it provides an interface to a drive system of the collector .
  • a solar collector assembly is provided with at least one ar- rangement of one parabolic reflector and at least one reflec ⁇ tor holder for holding the parabolic reflector, wherein the reflector holder is fixed to at least one edge of the para ⁇ bolic reflector.
