Hi all,
I want to know how PVSyst calculates TArray (for monofacial and bifacial modules)
As I can see in: https://www.pvsyst.com/help/thermal_loss.htm
0) This is the formula that uses PVSyst. Is it right?
1) Tcell is TArray?
2) U = to the value introduced by the user (for instance U=29 W/m2K) , or U is calculated (ignoring the fixed value introduced by the user)?
3) Alpha is always 0.9?
4) Ginc: Which variable is?
Ginc = GlobInc ?
Ginc =GlobEff ?
Ginc = (GlobInc + GlobBak) ?
Ginc = (GlobInc + BifacialityFactor * GlobBak) ?
5) Effic is always 10%?
I enclose different calculations I have made and the differences between calculations
Thank you in advance for your valuable support.
