Hi, We are a module manufacturer and would like to determine the best way to define a PV module in order for the most accurate simulations in PVsyst.  Bifacial modules have a front power spec, same as standard panels, and also a rear power spec which varies form 5 to 30% additional power based conditions. What is the best way to simulate a bifacial PV module?   Can transmitted, reflected, diffused light and module orientation be simulated?  Should different PV module definitions be entered corresponding to...say 10%, 20% and 30% gain in power to account for the rear power?  Or is there another method to most accurately model a bifacial module? Please advise.  Specification sheet attached Thanks
