linkeshd Posted August 24, 2018 Share Posted August 24, 2018 Dear fellow PVsyst users,I recently was surprized by some very large loss factors when using Boviet 6612P 320 Optimized modules, as shown:Crazy Big IAM Factor Losses Investigating the IAM curve, the Scandia curve looks really strange:Scandia Lab's IAM factor versus others In general, I thought that the Scandia model was experimentally confirmed. Is this the case? Has anyone seen this before? What would you consider a reasonable approach to this?Thank you,Link Link to comment Share on other sites More sharing options...
André Mermoud Posted August 28, 2018 Share Posted August 28, 2018 I really don't understand how you got this result. The Sandia model is hard-coded in PVsyst, the values are unmodifiable and give a result very close to the normal Fresnel's model.This curve is probably a user-defined IAM profile, specified in your PV module, with completely erroneous parameters. Sandia model and Fresnel, normal glass and with AR-coating Link to comment Share on other sites More sharing options...
