Is the average temperature taken by meteonom is for 24 hours or only during the solar generation time? In case we change the temperature value provided by meteonom, will it also affect the inverter derating curve and the module temperature coeffecient?

Hi, While generating a new site file and meteo file, the monthly temperature value taken by Metenom 7.2 is much lower than the real time temperature. I have used a site at Trichy, Tamilnadu, India where the real time average temperature is 33.5°C whereas Meteonom 7.2 gives a temperature of 27°C. Do we have to change the temperature according to real time manually or does PVsyst account for it during simulation?

Which losses would vary for string and central inverters and why?
