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
