  1. Thank you, I will try the 40 tracker cap modification. What value do you recommend raising it to, for example if I'm modeling a system with 5000 trackers?
  2. Hello, I am able to import a 2D layout from CAD to PVsyst near shading. However, I want to assign alternating East / West tilts to the modules, as in "domes". I am not able to do this because the modules are coming in flat, but all with the same azimuth. The only way to make them tilt in opposite directions is to change the azimuth, which causes them to rotate around their left corner references. Does anyone have suggestions about how to do this?
  3. Hi PVsyst team, I am noticing some changes in shading losses as I go through version updates. These are some general observations. Sometimes running the shading the first time generates different results than the second time. Sometimes the values within "irradiance loss" seem to reduce, while the values within "electrical loss" increase. In version 7.2.16, when comparing unlimited sheds (fixed tilt), vs. the same set of inputs in near shadings, the losses are more significantly different than they used to be in earlier versions. I understand you might need specific files to check what is happening. But can you comment generally on whether the shading calculation methods and algorithms are getting updated intentionally with version updates? We now have the capabilities to implement more and more complex shading scenes. Can you comment on how robust the calculations are with complex scenes? Do you have any recommendations for us as modelers to ensure that shading calculations remain accurate even when running complex scenes? Thanks in advance.
  4. The detailed near shading scene has some overlapping trackers. I wonder if this is causing an issue that interacts with the version change. Will report back.
  5. Thank you, Nils! Is there a general place to access these earlier .exe files, or do we need to request them here on the forum?
  6. Has anyone observed changes in global incident irradiance when changing from version 7.2.11 to 7.2.12?
  7. Hello, is there any way to revert back to a recent sub-version? For example from V7.2.12 to V7.2.11? I don't see the ability to download these sub-versions from the PVsyst website. Thanks in advance for the help.
