Rafael Santos Posted July 17, 2013 Share Posted July 17, 2013 Hi, I am a new PVsyst user as I used to only design wind energy projects.I have 1 year worth of data (global horizontal irradiation, temperature, wind speed and direction) measured on site.Which is the best source of meteo data? The long therm ones that come in PVsyst (NASA, Meteonorm) or my own measurements?Also, is it possible to correlate my short therm measurements with the satellite data? If I do this, would there result in a significant reduction in uncertainty?Lastly, are there any open source of hourly radiation data, (like MERA and reanalysis in wind)?Best regards,Rafael Link to comment Share on other sites More sharing options...
