A set of documented functions for simulating the performance of photovoltaic energy systems.
- [x] Closes #2504 - [x] I am familiar with the [contributing guidelines](https://pvlib-python.readthedocs.io/en/latest/contributing/index.html) - [ ] Tests added -- No tests were added - [x] Updates entries in [`docs/sphinx/source/reference`](https://github.com/pvlib/pvlib-python/blob/main/docs/sphinx/source/reference) for...
This paper provides a Newton-based method of finding the MPP, with the function and starting point constructed in such a way that they claim guarantees convergence. Rough timing (for 1000...
**Is your feature request related to a problem? Please describe.** - PAN files come in either a utf-8 or Borland Pascal format - Currently read_panond works for utf-8 format but...
Hi, I'd like to make this proposal to speed up the `"nrel_numpy"` version of `pvlib.solarposition.get_solarposition()` In this PR I just replace some of the native python loops with numpy equivalent...
The first solar spectral correction function `spectral.mismatch.spectral_factor_firstsolar` provides coefficients for a single `cdte` product, see [here](https://github.com/pvlib/pvlib-python/blob/6dfeaf8ee97db6a7a8f3c8109eed8b5d285c4e41/pvlib/spectrum/mismatch.py#L253). The coefficients are different from those found in the primary reference, the 2016 IEEE...
**Describe the bug** I am upgrading from pvlib version 0.9.5 and have noticed an issue when using the sun_rise_set_transit_spa() function to label nighttime points. I have attached three screenshot, one...
**Is your feature request related to a problem? Please describe.** `pvlib.tracking.singleaxis` returns NaNs for intervals where the sun is below the horizon. This can result in NaNs propogating to lots...
**Describe the bug** `hsu` model has one of its parameters `depo_veloc`, which is described as > Deposition or settling velocity of particulates. [m/s] The [original paper](https://ieeexplore.ieee.org/document/8735892) mentions that the equation...
The [Array API standard](https://data-apis.org/array-api/latest/) makes it possible to write generic code that works with many types of arrays (NumPy, Tensorflow, PyTorch, Dask, JAX, CuPy, MXNet, Xarray, ...). In principle, this...
> Would the powers that be be willing to make the component name’s consistent across all model functions? For example, perez returns sky_diffuse, while poa_components returns poa_sky_diffuse. It also seems...
