It sounds like the set of input data are
not consistent or are not complete. Are you also changing the other fields like
open circuit voltage? The bandgap and the number of cells in series have to be
consistent with the overall array power and voltage. I have seen this happen
before and it was bad input; we also see the same outcome in the TRNSYS
implementation of the same model.

Hello,
I have a problem when running my simulation when I try to input my own
parameters, which are from the PV manufacturer. I input the data and the
simulation runs fine when I tell it there are the "default" number of
cells in series (36). But the panel actually has 60, and when I use that value
the simulation crashes, the full crash, no warnings or errors. I tried multiples
of 36 (i.e. 72) but that didn't work.
I'm not sure if there is a mathematical problem during calculation.
Thanks,
Morgan
