Abstract: This paper was concerned with an experimental study of parabolic trough collector designed and manufactured. A parabolic trough solar collector uses Aluminium sheet in the shape of a parabolic cylinder to reflect and concentrate sun radiations towards an absorber tube located at the focus line of the parabolic cylinder. The receiver absorbs the incoming radiations and transforms them into thermal energy, the latter being transported and collected by a fluid medium circulating within the absorber tube.
