Buenas tengo una consulta, al generar el informe de pvsyst quiero que muestre la energia util a la salida del sistema ya que esa es la energia que se entrega. Pero no veo la opcion de añadirla en el informe. Les adjunto las variables disponibles para añadir al informe, gracias de antemano

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.

Hi all, I'm trying to find a variable that gives the Gobal Inclined Irradiance in actual plane of array AFTER backtracking. The closest I found in PVsyst output are: GlobInc: The problem of this one is that I understand it gives the idealised GInc if the trackers were always tracking the sun (i.e. without considering backtracking early morning or later afternoon). GlobEff: The problem is that this gives the effective global Inc after all optical losses. I need the value BEFORE optical losses but after Backtracking. Any advice? Basically I need the GHI transposed to the actual tilt angle, without any corrections. Regards, Ahmad
