Winter operating temperature below 0 Celsius

[spelland74]

Hello,

I am simulating a PV system in a location where minimum daytime temperatures in winter can reach about -30 degrees Celsius. Based on this, I think the minimum winter operating temperature for design should be around -10 Celsius, but PVsyst does not allow for values below 0 Celsius. Could you give some feedback on this?

Best regards,

Sophie

Sorry, this was a limit which seemed reasonable when I wrote this dialog. I have diminished it for the next version 6.44.

However this limit is not very significant (only used for sizing conditions).
