Previously when i was uploading the pan files , PVSYST use to take the Rseries values from pan file. but now when i am uploading the pan file the Rseries value is not getting modified. For ex : Rseries value in Pan file : 0.221ohm, and after uploading pan file in pvsyst it is showing 0.197ohm in model parameters. Please suggsest what can be done to resolve this.
