2021 Blind PVPMC Modeling Comparison – Call for Participants

Sandia National Laboratories is organizing a PV performance modeling comparison to provide an opportunity for PV modelers to test their models and modeling ability against real system data and also help to provide a baseline quantifying how much variability there is between different models and modelers.

The Due Date for all modeling submissions is Friday, September 10, 2021.  All information and datasets can be found at: https://pvpmc.sandia.gov/resources-and-events/2021-blind-pv-modeling-comparison/

Measured weather and irradiance data are provided along with detailed descriptions of PV systems from two locations (Albuquerque, New Mexico USA and Roskilde, Denmark). Participants are asked to simulate the plane-of-array irradiance, module temperature, and DC power output from six systems (scenarios) and submit their results back to Sandia for processing.

Sandia plans to present an anonymized summary of the results at the next PVPMC workshop planned for October 19-20, 2021 in Salt Lake City.  Following this workshop, Sandia plans to prepare a journal article to disseminate results with all of the participants included as co-authors (participants will have the option to opt out if they wish).

If you have any questions after reading all of the documentation please email Dr. Marios Theristis (mtheris@sandia.gov) and he will update the FAQ section of the webpage, as appropriate so everyone can view all the questions and answers.

Running all scenarios is optional, but strongly encouraged.

Thank you and we look forward to receiving your contributions!


By participating in this study and providing your results, we are assuming that we have permission to include them in the comparison and publish the results anonymously.
