In the release notes of the latest version of PVsyst (7.4.6), they specify that now when reading a PAN file the Rserie and Rshunt values are no longer modified, however, I was checking these values for multiple PAN files and they're still modifying them. The values that I'm seeing are the same as for previous versions.
If the model is still modifying the Rserie and Rshunt, what is this release note referring to?
