Dear all, Thank you for reading this post and I would really appreciate it if any advice could be given. I was always told that PVsyst has the ability to perform large-scale simulations in terrine areas. However, when I inputted the geographic model (made in blender or downloaded google map) into Pvsyst and clicked "fill zone", there is always penetration either between module-module or module-object. Is there any way that I could delete all overlapping objects with a single click or prevent overlapping objects to be created? Another question, I have been searching on the internet about this issue for quite a while now, and that I realized not one input the whole terrine into near shading. Is loading the horizon data enough? meaning this approach unnessery? Best regrads, Ivan Leung
Hello everyone, I've been recently introduced to the concept of backtracking. Based on what I understood, the trackers are tilted in reverse to solar tracking to avoid mutual shadings between PV rows when the solar elevation is low. In that case, I would expect that the near shadings losses would be 0 (assuming that there aren't any other surrounding obstacles in the scene such as trees). I simulated a project with bifacial PV modules in a N/S horizontal single axis tracker configuration. The elevation of each tracker row does slightly differ as indicated by the topography. However, currently, we cannot simulate such a scenario, thus we assume that all trackers are of the same elevation, orientation, and size. Considering this brief explanation, what could be the issue causing the near shadings looses to be non-zero when using backtracking? If interested, I can share additional details, Any feedback is welcome, Regards
In the Near Shading Tab, when computing the shading factor table i notice that when going from higher Pitch E-W to a lower one induces some shading at low heighta even with backtracking enabled. But then i go back into the construction perspective again and i close it out without changing any of the fields and recomputed the shading factor table, the shading in the low heights is not there anymore. Is this a glitch on PVsyst? If it is, It would be greatly appreciated if this can be taken, as i would have to run shading factor table twice every time i run simulation going from higher pitch to a lower pitch. Than k you,
