Sure @cwhanse, it seems easiest to do this at the time of merging.

Is this model for clear-sky conditions only, or all sky? Is it for 30-degree tilt only, a range of tilts, or any orientation? Any other restrictions or limitations the users...

The release note itself seems ambiguous, since the "Detailed PV Model" has several module and inverter options, and incomplete, since the parameters for those options aren't identified. Regardless, I think...

The following note from the SAM website may also be relevant: > Note: The PVWatts website uses a different version numbering system than the PVWatts model. For example, the website...

Is the overall idea to offer a complete set of functions for each (or at least more than one) pvwatts version?

I support those goals. Assuming that there will be several versions implemented eventually (someone might want to add older ones too) then probably there will be only a few base...

Does anyone else see the irony here? The opening line is: > I would like to mimic pvsyst so as to be bankable And: > It would be nice to...

If you have some data and are tempted to use interpolation, I suggest you also give the fitting routine for the ADR inverter model a try. It is located [here](https://github.com/adriesse/pvpltools-python/blob/master/pvpltools/power_conversion.py)....

Maybe we could join forces and publish a paper with a title like "Bankability assessment of inverter simulation models" in a publication that bankers read.

There are some graphs in these publications illustrating what can go wrong with generic numeric interpolation: https://www.researchgate.net/project/PV-System-Simulation-Software-Validation
