The present invention relates to a solar energy collector system, comprising:
- an elevated receiver (805) comprising a solar radiation absorber;
- a plurality of vertical support structures (810) configured to support the elevated receiver (805), the vertical support structures (810) being distributed longitudinally along a length of the elevated receiver (805); and
- an arrangement of longitudinal guy wires (830). Each longitudinal guy wire (830) extends between two adjacent ones of the plurality of vertical support structures (810), and the vertical support structures (810) and/or the arrangement of longitudinal guy wires (830) are configured to stabilize the solar energy collector system and to accommodate longitudinal thermal expansion of one or more components of the elevated receiver (805).
