Hi Edward, Thanks so much for your feedback! Yes, pvlib already uses the SciPy special Lambert-W function to solve the single diode equation. Please see the documentation: * theory: https://pvlib-python.readthedocs.io/en/stable/singlediode.html * Examples: https://pvlib-python.readthedocs.io/en/stable/auto_examples/plot_singlediode... * api: https://pvlib-python.readthedocs.io/en/stable/generated/pvlib.pvsystem.singl... And check the source: * https://github.com/pvlib/pvlib-python/blob/master/pvlib/singlediode.py * https://github.com/pvlib/pvlib-python/blob/master/pvlib/ivtools/sdm.py pvlib has only implemented published models, so it has only Desoto, CEC, SAM, and PVsyst models which haven't considered capacitance or inductance. But we would be interested in any publications you have on pv modeling and any pull request you'd like to contribute. Perhaps consider putting on the pvlib Google group? https://groups.google.com/g/pvlib-python Thanks again! Mark On Tue, Jan 12, 2021, 9:07 AM Edward Montague <sciwiseg@gmail.com> wrote:

Hi Mark,

I'm wondering if you might also make extensive use of the lambert W function to design the equivalent electrical circuit and perhaps consider inductive and capacitive loads upon that circuit.

Dear Pythonistas and solar power enthusiasts,

On behalf of the maintainers, we're happy to announce a new release of pvlib python: software for simulating performance of photovoltaic solar energy systems.

*See what's new for v0.8.1:* * https://pvlib-python.readthedocs.io/en/stable/whatsnew.html

*Releases are available from PyPI and the conda-forge channel:* * https://pypi.org/project/pvlib/ * https://anaconda.org/conda-forge/pvlib-python

*Read the Documentation:* * https://pvlib-python.readthedocs.io/en/stable/index.html

*Report issues & contribute:* * https://github.com/pvlib/pvlib-python

*Highlights:* * AirSpeed Velocity benchmarks are now available! https://pvlib-benchmarker.github.io/pvlib-benchmarks/ * A numpy-based implementation of the SPECTRL2 spectral irradiance model and a usage example in the gallery.

https://pvlib-python.readthedocs.io/en/stable/auto_examples/plot_spectrl2_fi... * New functions for modeling inverters with multiple MPPTs. * The Liu-Jordan irradiance function is deprecated, and will be removed in v0.9. Please use the newer Campbell-Norman function instead, but note it expects some different arguments. * Added the option of fetching 5 and 15-minute PSM3 data using a new "attributes" keyword argument. * Clear-sky detection now uses centered rolling windows instead of left-aligned rolling windows.

*The maintainers thank you for using pvlib python!*
