Hi Jonipa. A possible way to issue this error is go to the near shading scene>constructions/perspective and select all the trackers, then go to Tools>List and Management off objects (Ctrl+G) and modify the Tilt column to 0, this will erase all the tilt from the trackers (it is an aproximation because real trackers will have a little tilt when it will be implanted in the terrain) but should allow you to use correctly the bifacial scene for the modules. In general if the you have multiple different tilts the bifacial parameters will show you an error if the have a average difference more than 2º (this value could be seen in the advance parameters). I hope this solution could help you!

Thank you very much!, I will try to adjust the electrical effect. Kind regards.

Hi Michele. Please find attached the .shd in the next link https://we.tl/t-4wzvKGvVZt I will check the post mentioned. Thank you very much.

Hi all. With the recent update of PVSYST to the 7.4.0 version I have see that the shading electrical losses are too much higher comparing with the previous version. Launching the same simulations of a PV plant (using the same parameters and the same Near Shadows scene, the shadings losses goes from -0.34% (in 7.3 version) to -3.41% (in the version 7.4). Could it be a possible bug? Is is possile to the new version overestimate this kind of losses? Near and far shadow losses factors change too but the value are similar this only happens with the shading electrical losses. Thank you very much.
