Losess

[Zahra]

Hello,

I am conducting an experimental study on the degradation of a Building-Integrated Photovoltaic (BIPV) system, which uses a single semitransparent Photovoltaic (STPV) module on a facade at a 90-degree tilt connected to an EcoFlow portable power station that functions as both the inverter and battery. I am seeking guidance on the most accurate way to model this setup in PVsyst, as I have several questions.

1. Wiring Losses: For a BIPV system with a single PV module connected to an inverter with a 3-meter wire, is it more accurate to model the wiring losses in PVsyst as global wiring resistance or as a loss fraction at STC?

2. Module Losses: I was also wondering how to obtain information for Light-Induced Degradation (LID), module quality, and module mismatch losses. Are these parameters typically provided in the module's datasheet, or are they found in specific research papers?

Thank you in advance for your guidance.
