Dear Andre, I have monthly irradiance data at POA for the site I'm studying, but not yet at a higher resolution. Is it possible to take the monthly POA into account somehow in PVsyst? If so, how should I do it? Thank you

Hi, When we import monthly data from meteonorm, the source is indicated in the format: Meteonorm 7.1 (YYYY-ZZZZ), Sat=XX%, where YYYY and ZZZZ are the first and last years of satellite data averaged for the site. However, it's not clear for me what XX means. What is it? Tks
