A Problem with Big Power Plant Designs in Nb. rectangles in width (X)

[Tohid]

The Problem in PVSyst 7.4:

When designing a large-scale power plant, we run into a big problem in the "Near Shading" tab. The software does not allow us to put more than 100 for the "Nb. rectangles in width (X)". This is a major limitation for large layouts.

We know that the "Module Layout" tool is the accurate way to model things, but it is too slow and not practical for very big systems of several megawatts. It also doesn't fix the core problem we have with the partition limit in the first step.

Hi,

Indeed the maximum number of rectangles is limited to 100. However, in most cases—even for large-scale projects—each table typically contains only a few strings, so this limitation normally is not issue. For example, if each table includes four twin half-cell panels arranged in portrait orientation, and each row of panels in the table corresponds to a single string, then the table would require eight rectangles in width (x-direction).

Could you please clarify how the system layout is defined in your example? You can find more details about the partition model in the following help page
