An end seal arrangement for a Parabolic Trough solar Collector, PTC, comprises an elongated parabolic reflector trough and a receiver pipe arranged at a focus-line of the reflector trough. The end seal arrangement comprises a housing configured to be fixated to one short-end of the reflector trough, and an inlay configured to be inserted in the housing to slidably abut a circumference of the receiver pipe, such that the reflector trough is sealed to the receiver pipe by the inlay when the housing is fixated to the short-end of the reflector trough and the reflector trough pivots about its focus-line. The end seal arrangement further comprises a fixation means configured to fixate the housing to the reflector trough. By reducing heat leakage and prevent ice, snow, sand, etc. from deteriorating the reflector, improved operational performance will be achieved.
