ERROR in the CEC Performance Model with User entered Specifications was created by Mykhailo
Hello Forum,
can somebody help me with my issue?
I try to add PV Module with user specifications, but when i click button "Calculate and plot" i have fail (-33)...
[Could not solve, sanity check failed (-33): abs((P - Pmp) / Pmp) > 0.015]
But all parameters were taken from the manufacturer's official website.
Module name: ABI Solar АВ340-60MHC
Pmax = 340W
Isc =10,55A
Voc = 41,7V
Impp = 9,96A
Vmpp = 34,2V
Nominal Operating Cell Temperature (NOCT) 45±2 °C
Temperature coef's of:
Pmax = -0,360 %/°C
Voc = -0,280 %/°C
Isc = 0.048 %/°C
My entered parameters:
Please, help me get a plot like this:
Thx.

Hi Mykhailo,
Please try changing the number of cells in series from 12 to 60. That results in a set of I-V curves that look similar to the one on the manufacturer spec sheet:
Best regards,
Paul.
