Requesting feedback on Sandia’s PV Performance Modeling Idea No. 2: Irradiance transposition

[mtheristis]

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.

Do you have any data to back up the claim "Gaps were found in available model chains for tilted-plane irradiance at high latitudes"?
