FIxed: [version 7.2.20] Electrical shading losses and partitioning issues for trackers

[Michele Oliosi]

Patch 7.2.20 has introduced an error affecting the partitioning into rectangle strings of tracker objects.

The partitioning, either via the object management window or the individual objects edition windows, will not respond correctly to the inputs such as "number of partitions in X", and will not draw the partitioning correctly either. As a consequence, the shading animation and calculation of the electrical shading factor table will give erroneous results. Typically this yields 0% electrical shadings in the yearly results or losses diagram.

This bug affects trackers only. For previously created projects, the trigger for the bug is opening the 3D scene and the tracker object definition, which will break the partitioning.

We know of no workaround at the moment, but are working to provide a patch very quickly for this error. It should be published within this week.

In the meantime you can also work in the previous version 7.2.19, while waiting for the patch. For that you need to uninstall and reinstall PVsyst. This has no averse effect on the licence, which stays active through the process.

Recently released v7.2.21 should fix the bug.
