@kanderso-nrel that bottom panel is an eyebrow-raiser. I had not seen that result before. Although ground-reflected irradiance onto the front surface is a very minor part of plane-of-array, that figure...

I think there's room and use for both models in pvlib

About the initial temperature - if in doubt, make it a user input. I'll look through the paper and look forward to the PR.

pvlib relies on the published sources for validation of the algorithm. If you are asking about functional testing for pvlib, we test for correct calculation, and its OK to create...

If you can't get some code from FS, I could implement in Matlab. If our two calculations agree, that's enough evidence for me that the calculation is correct.

I thought that might come up when you mentioned view factors. Here's where this effort intersects with the bifacial model effort. I'm guessing this model assumes that the sky dome...

The module-to-module view factor can be computed using the "crossed-string" approach, see Eq. 4 in the Appelbaum paper. Although I share your view that the front and rear surface temperatures...

IMO a separate PR for the view factor functions makes sense. I'd put the functions in `pvlib.bifacial`

I agree with Anton on the factorization. Sent from my iPhone On Jan 31, 2018, at 1:12 PM, Anton Driesse wrote: I don't think singlediode() is the right hierarchy level...
