[PAN file: Different Rs(sometimes Rshunt also) in Model parameters and Additional data]

Hi all,

Is there anyone who knows how to solve the problem below?

=======

I used "Optimize Rs" in Additional data and got Rs = 0.186 ohm/ Rshunt 700 ohm. At this step, both Rs and Rshunt in Model parameters and Additional data are the same.

Then, I saved the file.

However, when I opened the file again, Rs became 0.192 ohm in Additional data while Rs still remained 0.186 ohm in Model parameters.

Anyone knows why this happened?

[Set default for shunt resistance]

Hi all,

I was trying to check Default for shunt resistance, but the small check showed at the right side, not inside the box.

Did I set up the default successfully?

[Relative efficiency]

Hi,

I'd like to the know the differences between the two rel. efficiency as marked in the attachment?

The left one: If it's relative effic. by respect to STC, why is there -0.57% at 1000W/m2? shouldn't it be zero?

Thank you.
