PAN file parameters controlling low light loss

[laurahin]

Hi,

I'm unsure what PAN file parameter(s) control the low light losses for a given module.  From the documentation, it seems that Rserie is the most important, but I did some tests and found that Rshunt had a greater effect.  In addition to this, the PAN file I'm working with includes efficiency values for different irradiance both at the end of the general list of parameters (variable names like RelEffic800) and in a list of OperPoints at the end of the file.  (The values are the same.)  I can remove either or both of these lists and the low light loss comes out the same.  Are these even used?  Perhaps the other parameters are based on fits to these curves, making the curves themselves redundant?  Please clarify.

Thanks,

Laura
