Following up on this, I reverted back to version 8.0.1 and I am no longer having this issue. So it seems like a bug was introduced at some point.

When importing a weather file for a new project, I am getting an error that says "Invalid weather file: The hourly data are not defined." I am using the same process I have always used, where I define the coordinates of the site and then import weather data from SolarAnywhere (see screenshot), but not I am getting this error which I have never gotten before. I also tried using NREL/NSRDB, and I am getting the same error. Is this a bug? I just updated to version 8.0.17.

I am running a project that has fixed tilt arrays in an east-west "dome" orientation. So half of the strings are tilted 5 degrees facing west, and half of the strings are tilted 5 degrees facing east. I need to get POA irradiance values (GlobInc). I am wondering how PVsyst calculates GlobInc when there are multiple orientations like this. Is it an average value for the whole site?
