Question

The question in solar energy engineering:

Please explain the steps needed to find Ht (solar insolation) for parabolic trough collector?

Answer 1

The steps to follow for parabolic trough Collecto A parabolic solar collector uses a mirror types of parabolic cylinder to reflect and concentrate sun radiations. The receiver absorbs the incoming radiations and transfer them into thermal energy. And this is also having some of the Advantages. Those are o sim- plicity and low cost @ Betes performa nce and good quality of product S. In this our main view is now can we follow the steps and what are they. Those are O Dimensions and parameters 3. Préparation of the materials @ making the back @ making the ends s making the cover Joining the back and the ends.

o Joining the cover © The bearing and the secever @ The edge redressing mechanism The body sedressing mechanism The photo electric detector The chasis @ The controller and the tracking gear The fluid cisewation system and © the The optical adjustment and collecting tests. For the above steps here is the overall explanation. The collector is a symm etrical section of a parabola around it's ver- ter and also it's have focal line parabo- points of by consist of focal lic Soss-section. And the entered reflected and pass es Dadiation is And for this through focal line. parabola in sepresentation of y= AS f- focal length

for this tsough there some parameters are D trough length I also there. I those 2) focal length 3) aperture width aña are there used to form o dim angle. Size of trough And also the focal length as - Shape parametey and And also y 25 (95)

And the avera is cali curated a Caliculated A n 16V And the concentration ratio is Aap. c. CG App. And further we have to coated mirrors like silver coated type. And also the mirror mate bials have alterna- tive type for a type of mirror there are some layers are eùst in between ME solar Jacques layer system Aluminium Stoip L Anodised x layer protect Joyer
