GHI, DHI, ambient temperature, wind speed,

or

POA irradiance (GlPMeas in the custom meteo menu), ambient temperature, wind speed

 

But because i am using bifacial panels, I have PAO at the rear and front side, how do i implement this?

Also I was wondering if it is possible to costum a meteo file with only 1 month worth of measured data?

Import front side irradiance as POA in PVsyst. I do not believe it is possible to import rear-side irradiance. To achieve the best results, it is best to import measured GHI and measured DHI. For a vertical bifacial system if you have GHI (with or without DHI), it will be better than POA. I do not think PVsyst can properly calculate GHI and DHI if using POA from a vertical bifacial system (a PVsyst admin should comment here).

Yes
