bkn Posted March 22, 2019 Share Posted March 22, 2019 Hello guys,I find it a bit confusing when in comes to selecting "Field type" in "Orientation" box especially about the notion of "unlimited ~"In PVsyst help, the following explanation presents:(http://files.pvsyst.com/help/orientation.htm) Unlimited sheds: To be used when the sheds are very long with respect to their width. If the sheds are too short as one cannot neglect the edge effects, you should define sheds in the "Near shadings" CAO option instead.And, "Horiz. axis, unlimited trackers" is not explained in this chapter.Here are my questions:1. How "unlimited sheds" in fixed and "Horiz. axis, unlimited trackers" hold the sun position? As an example, how am I supposed to know the rod of the tracker is aligned to N-S direction or W-S direction in "Horiz. axis, unlimite trackers" ? how to vary the simulation between the rod aligned to N-S or W-S using in "Horiz. axis, unlimited trackers"?2. I tried to google and could not find the definition of "the edge effect" indicated above "Unlimited sheds". I just saw "cloudy edge effect" but it seems that the edge effect input by PVsyst sounds different. What is the meaning of "edge effect" in PVsyst simulation?3. What would be the major difference the selection of "Horiz. axis, unlimited trackers" vs "Tracking tilted or horiz. N-S axis"? What I mean, which case would be the exact case of using each "Field type"? What I found is that it only difference comes from "the edge effect" seemingly.Thanks in advance, Link to comment Share on other sites More sharing options...
