As part of the Sandia’s PV Performance Modeling program (https://pvpmc.sandia.gov/), we are sharing our model development ideas to seek feedback based on relevance, importance, and potential impact.

Your input will help us prioritize our efforts for fiscal years 2025-2027. Any model developments from our PV Performance Modeling program will be validated, documented in peer-reviewed articles, and made available in pvlib-python. If you are already working on a similar idea, please reach out—we would love to collaborate!

Idea No 2. Improve and validate irradiance models for systems at high latitude, or vertical E-W configurations: Gaps were found in available model chains for tilted-plane irradiance at high latitudes. We could 1) add the best-performing models to pvlib, and 2) assess pvlib irradiance transposition models against real data.
