1. PV Array: 18 mod., 3 rows of 6, portrait, 1.64m X 1.0m ea., 6 mod./string.
2. Orientation: array azimuth: 186 deg. (6 deg. w of s), array el.: 20 deg.
3. Array sits on a roof with orientation: azimuth 77 deg. (13 deg. n of east), roof el.:20 deg. Flat roof.
Question 1: Does self shading module in SAM assume arrays sit on a horizontal surface?
Question 2: If the answer to question 1 above is yes,is there any way to modify input so SAM will give reasonable guess as to required spacing between rows for minimum/reasonable self shading for non horizontal mounting surface ?
Question 3: If the answer to question 1 above is no, how does SAM account for mounting surface azimuth and elevation ?
The attached is not my array, but its similar to what I'm trying to explain. My latitude is 33.2 deg. n.
Thank you,
J.P.M.
