Heliostat layout in Northern and Southern hemisphere locations- A conflict!

Hi Paul,

It has been claimed that (Wagner thesis, page 26, 37-38) for the solar tower model, the density of solar field layout in northern and southern hemisphere locations should be different. In northern hemisphere, the density of solar field in north of the tower should be more, whereas in southern hemisphere, the number of heliostats in south of the tower should be more than that of located in the north of the tower. However, when I am trying different northern and southern locations, the results are the same, and in all cases the number of heliostats in north of the tower is more than that of in the south. Can you please suggest why this happening?
I have attached an example.

Thank you for your time and consideration.

P.S. The arrow indicator in the solar field layout towards the equator either for northern or southern locations

Dear Saeed,

The screenshots in the document you attached seem to confirm your expectation. For the northern hemisphere location, the top of your computer screen is north of the equator (the arrow in the diagram points south toward the equator), and the area of the field shaded in red is larger north of the tower than south. For the southern hemisphere location, the top of the screen is south of the equator (the arrow points north toward the equator), and the shaded area is larger south of the tower than north.

Best regards,
Paul.

Dear Paul,

Ohh..! Yes..! I though the arrow points south in both cases! Sorry for my confusion.

Warmly,

Saeed
