Additional context
(if this issue have to be a Support question, I re-ask in StackOverflow)
@miettal thanks for pointing out this shortcoming in the documentation. I think we can add text to each function's docstring. The racking_model keyword for pvlib.pvsystem.PVSystem doesn't provide much explanation either, but that could point to the documentation for functions in pvlib.temperature. Pull request welcome.
