Thank you for the quick reply. However, the values from my screenshots before don't seem to match the values in the following windows, even though the same module was used: In my original post Voc was at 49.4 V at -10 °C. In a string with 30 modules this adds up to 1482 V, which fits to the first screenshot in this post. However, at -15 °C PVsyst previously calculated a value of 49.6 V. With 30 modules in series this should of course then add up to 1488 V. Yet in this case PVsyst calculates a value of 1501 V. Any thoughts?

Hey, please take a look at the following three screenshots. From -15°C to -20°C the Voc value gets reduced. Is this supposed to happen? I was under the impression that the lower the temperature the higher the Voc value gets. BR and thanks, Dominik

Hello everyone, the following section of the PVsyst-help suggest a "limit shading" profile angle of below 18 ° to 20 °: https://www.pvsyst.com/help/shed_optimization.htm However, I noticed that in my simulations higher energy yields will be calculated when setting higher values for that angle. Is it possible that this section of help needs to be updated to consider the commonly used half-cell technology as well? I suspect that since the two halfs of the modules can function seperately (gound-mounted system, fixed tilt, vertical orientation), the larger shading has less of a negative effect than the positive effect of the better tilt for the sun (middle-european project locations). And since formerly by shading a part of the module the whole module was affected it was much more important to avoid shading, therefore the values of below 18 ° to 20 °. Thanks!
