Welcome to the bifacial_radiance wiki! Here we try to answer some of the common questions we get by e-mail, as well as explain some of the tricks to better use and understand bifacial_radiance.

IF you have found an issue / or have doubts, contact us through Issues and we'll try to help!

Webinar Training:

If you want to understand the framework over which bifacial_radiance was created, how to work with the code, jupyter notebooks and GUI, we suggest you look at our Tutorial Webinar, with the slides available here.
