How can I Change the state in .PAN file instead of doing it into the pVSYST and saving.

And how this can be tracked in PAN file ?

While importing the PV module PAN file and updating the IAM values in it, the default values are being applied instead of the user-defined ones. The user-defined values are only being applied when I manually select the user-defined profile. However, in earlier PAN files, the user-defined values were automatically applied from the PAN file. Please suggest why this is happening and what corrective measures can be taken to resolve this issue.

According to the manufacturer the module efficiency cames out to be 21.50%. but it is showing 21.53% in loss diagram. Does this efficiency PVSYST chooses from their own calculations using Internal model result tool.

Please provide instructions on how to do the simulation for the above

while selecting an orientation, i want to simulate for HSAT and Fixed tilt both. How can i do the simulation for both cases in a single simulation. Secondly, does it possible to select the both the losses in a single simulation? MV Line Loss 0.50% MV Line Voltage 33kV IDT Loss 0.10%, 0.90% HV Line Voltage 400kV HV Transformer Loss 0.04%, 0.23% 400kV Transmission Line Loss There is any way i can take both MV and HV losses 0.15%

I am seeing the pan file of a manufacturer and found that 1) Pmax temper. coeff. is not matching in Pdf pan file and datasheet (-0.32%/°C vs -0.35%/°C) 2) Voc temp. coefficient (MuVoc) is not matching in Pdf pan file and datasheet -128 mV/°C = - 0.256 %/°C vs -0.27%/°C) 3) Isc temperature coefficient (muIsc) is not matching in Pdf pan file and datasheet -5.2 mA/°C = 0.3719 %/°C vs -0.045%/°C) What could be the reasons? and How to convert muIsc in mA/°C to %/°C? Kindly help

I have simulated the PVSYST for two different solar manufacturer with keeping the all the parameters same. the results of 25 years are varying. The difference between the generation should be same if we are considering degradation/year factor same for both manufactures but in this case difference is varying with the large difference . please help me out. Year 1 2 difference E Grid E Grid E Grid MWH MWH MWH 0 40907 40368 539 1 40681 40133 548 2 40432 39881 551 3 40159 39612 547 4 39862 39324 538 5 39523 39004 519 6 39147 38655 492 7 38763 38301 462 8 38380 37951 429 9 38007 37614 393 10 37680 37325 355 11 37400 37085 315 12 37136 36859 277 13 36884 36640 244 14 36640 36424 216 15 36415 36213 202 16 36200 35999 201 17 35971 35765 206 18 35716 35501 215 19 35427 35199 228 20 35044 34804 240 21 34572 34319 253 22 34071 33805 266 23 33554 33277 277 24 33035 32747 288

When comparing different manufacturers for a particular site, I obtained the results which are varying. Are there any default parameters for PV loss due to irradiance levels and PV loss due to temperature in PVSYST? On what parameters do these factors depend? Is it possible to get gain due to loss from irradiance levels? What should be the ideal values for Module quality losses?

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.

How to download .Pan file from PVSYT. ? I want to update IAM values in .PAN file but there are no IAM value instead some Oper points are listed.please reply
