Question about Sandia IAM Model Parameters in PVsyst

[zhangc]

Dear PVsyst Forum,

I have encountered an issue with the Sandia IAM model implementation in PVsyst. I found the values for the six parameters of the Sandia IAM model in the help documentation and used them to calculate the IAM value. However, the result I obtained does not seem to match the expected outcome.

I understand that the Sandia IAM model has been deprecated, but I am trying to compare the results from different IAM models, so I need to calculate the results using the Sandia IAM model.

Could anyone explain why the calculations might not be giving the correct result? Are there any specific conditions or considerations I should be aware of when using these parameters in PVsyst?

Thank you in advance for your help!

Best regards,
Zhang Chao

Yes, sorry, there are errors in the parameters of the help. We have to correct them.

Here are the correct parameters:

This gives this curve:

Thank you, André Mermoud. I obtained the correct IAM curve using the corrected parameters.
