Pvlib python 0.9.1 released

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 v0.9.1:

Releases are available from PyPI and the conda-forge channel:

Report issues & contribute:


  • Beautifully updated documentation theme that we hope is easier to browse and navigate. Please share your feedback!

  • Implementation of pvlib.temperature.prilliman, a transient weighted moving-average temperature model by Prilliman, et al. , to calculate back of module temperature from high-frequency sub-hourly irradiance input to account for different characteristic timescales between heat transfer and power conversion.

  • New infinite sheds model for either bifacial or monofacial modules, that calculates row-to-row shading and view factors for sky and ground reflected diffuse irradiance. Use pvlib.bifacial.infinite_sheds.get_irradiance to calculate the plane of array irradiance, all its components on both front and back sides, and the total from both sides.

The maintainers thank you for using pvlib python!
