Voc Calculation

[Guilherme de Almeida Ponce]

Hello, my name is Guilherme and I'm studying the One-Diode Method used on PVSyst.

I'm interested in the Voc calculation because when i read the calculus description on PVSyst I couldnt find anythis about thais calculatoin in expecific.
PVSyst quoted SANDIA MODEL, in their method they have a specific equation for Voc, I'm trying tio find it, the equation for Voc and it's variables. To be more especifc, how Voc varies with irradiation and temperature.

Thank you everyone and have a nice day!

Good Morning,

i have the same question as Guillerme. Can someone from PVSyst support give feedback?

Good day,

Same question about the Voc correction. From my project, the modules per string could increase to 29 with Voc correction. But according to the project setting, I set the minimun temperature as the lowest ambient temperature(as from the project,the array temperature is corrected by the Tamb. ), and it turned out to be 28 modules per string. Much appreciate if PVsyst can explain about the Voc corrected by the Tarray and GlobInc. Any information will be really helpful.

Thanks!

Kenny
