Is there interest in implementing a .pan or .ond reader into iotools?

[ckrening]

I find that .pan or .ond files are the most widely/easily available files containing parameters to use with the existing module and inverter models in PVlib. I have created read and parse functions to streamline getting those parameters into my code.

Would enough people find this feature useful that I should create a pull request?

@ckrening there is significant interest in having this capability. Pull requests welcome :)

Yes! This has been discussed several times over the years, but nobody has taken the initiative to do it. Here are some related discussions, for reference:

• PAN and OND readers on the draft roadmap: pvlib development roadmap #1581
• PVsyst inverter #1002 (comment)
• Auxiliary equation for PVsyst shunt resistance may be incorrect #1094 (comment)
• https://groups.google.com/g/pvlib-python/c/PDDic0SS6ao/m/Z-WKj7C6BwAJ

Any chance you can reuse our port @frivollier https://github.com/frivollier/pvsyst_tools

Thank you all for the suggestions! I went ahead and created a pull request #1749 using the code I had already created. I took a different approach than the suggested #1002 and #1094. There are trade-offs for either method but, please review and we can discuss what is best!
