Abstract: A solar trough system of the invention comprises at least one trough-shaped reflector surface (1) directing beams coming from the sun to the focal axis (F); at least one thermal receiver (2) disposed at the focal axis (F) and extending along the reflector (1). Furthermore, the system comprises at least one first arm (L1) and a second arm (L2), one end of each of which are connected to two fixed points (P1, P2) with swivel joint; at least one third arm (L3) which is connected to the other ends of these two arms (L, L2) from two points (P3, P4) with swivel joint wherein the thermal receiver (2) is connected with swivel joint to a linear movement point (E1) on the third arm (L3) which moves with rotation of the first and second arms (L1, L2).
