Hello,

I am having issue with entering in the "CEC performance model with user entered specification" for a 585 watts bifacial module.
Pmax=585
VMP:34.3
IMP:17.06
VOC:40.7
ISC:18.32

Temp Coefficient Pmax : -0.34%/C
Temp Coefficient voc : -0.26%/C
Tep Coefficient ISC: 0.05

Module area: 2.83012 m^2

number of cells in series: 120 [2 x (10x6)]

I keep getting error "failed to solve for module coefficient.": 

Please advise,

Hi Tokoyoshi,

This is a problem with modules with rated Imp > 15 A and will be fixed for the next version of  SAM, which we plan to release in a few weeks. Please see this post for details:

Best regards,
Paul.
