When importing own Meteodata relative humidity (RH) is required in PV*SOL premium. In https://help.valentin-software.com/pvsol/2020/calculation/pv-modules/ it is shown that RH is used for calculation of the module temperature. However, in the description of the module temperature calculation (https://help.valentin-software.com/pvsol/2020/calculation/pv-modules/module-temperature/) I do not find that RH is used.
I would appreciate an explanation, with formula in which RH is used, since we are at Mälardalen University writing a report on comparison of different software for PV yield calculations in Sweden.
