Applying Correction factors for VOC

[BMW]

Hi
Wonder if you can help think it's me being a bit dim but can't help that.
Normally I compare the calculated VOC against the measured VOC however on the Panels I normally used on the Spec sheet it has a Module Temperature coefficient which is normally -85mV/deg.

Now we have started using different Panel which has confused me. On the Spec sheet it has 3.

Temp Co of Pmax -0.45%K
Temp Co of Isc 0.038%K
Temp Co of Voc -0.34%K

Now 2 questions I assume I use the Voc one but how do I do it? I'm use to mV/degC not %K what does K mean? how to I use this new formula?

Cheers

Hi
K=Kelvin, doesn't really matter ( -0.34%K = -0.34% DegC)
This means you have to consider a decrease of 0.34% (when T raises above STC)
