Hi everyone, I’m currently working on generating BSDF data for a photovoltaic (PV) module using Radiance’s genBSDF, with the goal of performing glare simulations (e.g., DGP analysis). I’ve encountered some challenges starting from scratch and would greatly appreciate any guidance:
- What’s the best way to prepare the geometry, material definitions, and genBSDF parameters? Are there any beginner-friendly tutorials or learning resources?
- Given the complex structure of PV modules (e.g., highly reflective glass cover, EVA, solar cells, opaque backsheet), would it be better to model them as multi-layer systems (e.g., two or more layers), or is a single-layer representation preferred?
- I’ve reviewed several papers, but most focus on window modeling (often using the Window program to generate XML files). There seems to be limited guidance on modeling non-window, multilayer PV modules.
- Are there any example files, modeling strategies, or BSDF templates available for PV components?
- I’ve tried exporting geometry from Rhino, but the resulting
.radfile is extremely large—possibly due to mesh density or improper modeling methods?
Any suggestions, shared experiences, or references would be greatly appreciated. Thank you!
