Hello Forum,
today I've tried adding a PV Modul to SAM. The specifications are from the manufacturer of the module. After entering
the specs I clicked on "calculate" in the "Current-Voltage (I-V) Curve
at STC" and got the error message "could not solve, check inputs".
I checked the specs again but didn't find any deviations from the manufacturers fact sheet.
I tried to run a simulation and got the error message:
"exec fail(pvsamv1): CEC 6 parameter model: Could not solve for normalized coefficients. Please check your inputs.
Simulation pvsamv1 failed :exec fail(pvsamv1): CEC 6 parameter model: Could not
solve for normalized coefficients. Please check your inputs.
gen not assigned
Simulation grid failed :gen not assigned
SSC requires input 'gen', but was not found in the SAM UI or from previous simulations
Simulation utilityrate5 failed :precheck input: variable 'gen' (System power generated) required but not assigned
SSC requires input 'annual_energy_value', but was not found in the SAM UI or from previous simulations
Simulation cashloan failed :precheck input: variable 'annual_energy_value' (Energy value) required but not assigned"
I 've added a screenshot of the entered specs. Disregard the "Calculated STC Single Diode Model Parameters", as far as I remember, these where added when I clicked the "copy module specs from currently selected CEC database module". Before that, the "Calculated STC Single Diode Model Parameters" window was blank.
When I enter the same PV Module specs in PV*SOL it works and I can run simulations.
I hope somebody can point me in the right direction, because I don't know what to do else.
Thanks in advance.
