PV temperature compensatin value
I have been looking at some panels for expanding my system.
I have used the Outback Array sizing tool and went looking for the TC value for the panels. Couldn't locate it.
As a default I used the values in the Array sizing Tool
I am comparing 110W panels with very similar Amps at 12 V.
I looked at the spec sheet for my other Toshiba's and they list a value of -.346% / degree C for Voc.
Can't seem to get the Tool to show me the default right now???
Q: How different can the values be for different panels?
