Aaron3707 Posted July 7, 2022 Share Posted July 7, 2022 Dear PVSyst Team, I have encountered a situation whereby when importing a tracker array shading model .PVC file into PVSyst and running the first shading table analysis, I am able to obtain one type of shading table as seen in the first image below. The second image shows the shading table for the same exact shading model but a re-compute of the shading table after entering the shading model and exiting without doing any changes and when prompted by PVSyst to recompute, we just clicked yes. The shadings are now different compared to the first run. Moreover, I noticed that this results in the Phi Limits of the backtracking strategy to go haywire. In the first run, the limits seem to conform with what is expected, +/- 54.2 degrees. However, after the re-compute, the limits now go to +/- 79.9 degrees. (3rd and 4th image) Why is that? This causes the electrical shading loss in the loss diagram to double compared to the original first run (as seen in the 5th and 6th images respectively). However, sometimes, after the re-run, we would still end up having the limit angle be completely fine (i.e., it does not go to +/-79.9 degrees but instead, our electrical shading loss remains at 2.03%. Why is that? Looking forward to hearing from you guys soon. Thanks. Link to comment Share on other sites More sharing options...
