measured performance parameters

[fellanour]

Hi,

i want to find the performances parameters (yf,ya,yr,PR)from measured data using PVsyst software.

i used a Tools>Import ASCII Hourly file.after that i used Tools>Data tables and graphs, all variable can plotted correctely but Special Graphs for measured data its does not work correctely .

are there any other methodes to find measured (yf,ya,yr,PR) in PVsyst.

i had already 4 years stuck in this step.

with every version of PVsyst i hope they fix that but the same problem .

please any suggestion.

thank you very much.
