PV Performance Modeling and Stakeholder Engagement

Summary

Sandia National Laboratories' PV Performance Modeling and Stakeholder Engagement project, with a budget of $3,837,000 from 2021-2024, aimed to enhance PV model functionality, validate their accuracy, and foster stakeholder engagement. The project involved 49 organizations from 17 countries, producing 14 journal papers and releasing 13 pvlib-python versions with 28 enhancements. It hosted 5 PVPMC workshops with about 700 participants and saw its website attract over 50,000 visitors annually from 202 countries. Key findings include that existing models are simplistic for complex systems and conditions, system-specific data is crucial for accuracy, and industry confidence requires more accessible data. Quantitative results showed modeling accuracies, such as a 0.1-0.3% maximum power prediction for silicon modules, and identified a power normalized bias error range of -5.2% to 4.5% in blind modeling comparisons.
