@ Sebastian, Franilena and Paul.
From literature irrespective of the orientation of the collector, the tilt angle can be taken as the absolute value of latitude of the study site or the latitude multiply by a factor depending on the value of the site latitude. For a site latitude less than 25 degree the multiplying factor is taken as 0.87. From www.retscreen.net taking the absolute value of the site as the tilt angle will in general maximises the annual solar radiation in the plane of the solar collector. The information can be verified please.
My best regards.

Dear Mohammed,

For parabolic trough systems, there may be some design considerations that constrain the tilt angle optimization. Although the rule you describe is reasonable for maximizing collection of solar radiation over the year, you might choose horizontal collectors to minimize the cost and design complexity of support structures for steeply tilted collectors and minimize the complexity of the heat transfer fluid pumping system.

You can also use SAM's parametric simulations to find the optimal tilt angle for a given location.

Best regards,
Paul.
