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:* * 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:* ** *Beautifully updated documentation theme that is easier to browse and navigate. Please share your feedback! * Implementation of pvlib.temperature.prilliman <https://pvlib-python.readthedocs.io/en/stable/reference/generated/pvlib.temp...>, 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 <https://pvlib-python.readthedocs.io/en/stable/reference/generated/pvlib.bifa...> 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!* -- Mark Mikofski, PhD (2005) *Fiat Lux*
