Helios210 Posted December 8, 2020 Share Posted December 8, 2020 (edited) When using SolarGIS prospect data and the PVsyst synethetic generation algorithm I frequently get:"December has a great discrepancy of time shift with respect to the average."This might make sense if I was using hourly data from SolarGIS but this is hourly data that PVsyst itself has generated!Looking at the best clear days graph for the site clearly shows something wrong for December but I don't know how to fix this.Anyone else noticed similar problems/behaviour?H.Edit 1:Added pictures.
