Data driven model

[jacktang]

Hello, now we setup pvlib simulation by determined physical parameters, and i wonder is there any alternative to train the pvlib model by existing generation data and weather data?

pvlib does not offer that, as it's only an aggregation of models and wrappers to ease their use. I recommend you use your historical data to do that manually, choosing the models and values appropriate for your plant. And by using the same ones in the future, you can have an insight on degradation.

There are other tools out there, that may help you when only the power output timeseries is known. E.g.: https://solar-data-tools.readthedocs.io/en/stable/
