@cpr-chas I think `pvlib.shading` should contain functions for: - effects-level shading models (e.g., [Deline's ](https://www.researchgate.net/publication/273227488_A_simplified_model_of_uniform_shading_in_large_photovoltaic_arrays)approach) - functions that adjust direct and diffuse irradiance for far- or near-field objects, e.g. #758...

@cpr-chas I wasn't requesting that you tackle all three of those categories, I merely wanted to communicate my perspective on this module's scope, and that design for internal reuse is...

> I don't recall if there was a block other than lack of time. That's mostly it. NREL also wants to open source the production of the CEC module file....

As an interim, we could update the file distributed with pvlib-python to the current SAM release.

On second look, the block of code referencing the `location` instance isn't executed, it's there to show how ghi is obtained from cloud cover. Maybe we can display that information...

@soma2000-lang certainly. My idea is to replace these lines with math (for the last three lines) and provide a reference to the [cloud_cover_to_irradiance_clearsky_scaling](https://github.com/pvlib/pvlib-python/blob/df1c56e92d91701319adad4fe5cf98837edad0fb/pvlib/forecast.py#L466) function E.g., GHI = [offset + (1...

I agree, `pvlib.inverter.pvsyst` would be a good addition. In the case of PVsyst option 3, input consisting of three efficiency curves at 3 input voltages, these data are typical for...

I think @frivollier has shared some [tools ](https://github.com/frivollier/pvsyst_tools) to read OND and PAN files. I would support adding capabilities to pvlib, either directly or by importing from @frivollier 's project...

> Just curious, is that still the case? AFAIK, yes.

OK with me to close, or to keep the issue open. It would be nice to have the Pvsyst inverter model in pvlib, the real blocker is the lack of...
