Insights from the 2024 PVPMC Conference

May 17. 2024

The latest strides in photovoltaic (PV) technology and performance modeling were on full display at the 2024 PV Performance Modeling Collaborative (PVPMC) conference, organized and facilitated by Sandia National Laboratories. With a mission to enhance the precision and technical robustness of PV performance models, this collaborative effort was poised to revolutionize how the industry evaluates and invests in utility-scale (10MW+) solar energy projects.

The PVPMC workshop served as a nexus for PV professionals keen on refining performance models and analyses. These models, crucial for assessing current performance metrics and predicting future energy yields of PV projects, hold significant sway over investment decisions within the financial community. The more accurate and reliable these models become, the lower the financing costs, and the greater the proliferation of solar projects. It was a win-win for electricity consumers, investors, developers, and the planet.

The workshop provided a unique opportunity for professionals from diverse backgrounds to come together, fostering a vibrant atmosphere of learning and networking. A range of topics included Site and Design Impacts; Modeling Snow Effects on PV Systems, Underperformance of Assets, P90 and the Financial Value of Accurate Modeling, Solar Resource Assessment, among others. Engaging discussions, insightful presentations, software demonstrations, and collaborative workshops allowed attendees to exchange ideas, forge new partnerships, and deepen their understanding of PV performance modeling.

The workshop showcased many distinguished speakers, including GroundWork’s own Alex Bryan. He presented an improved approach to gap-filling of global horizontal irradiance data in solar resource assessment, which significantly reduces errors during gaps, particularly under unstable (i.e., partly cloudy) skies. Annalise Miller from Luminate, an independent engineering firm, presented on Improved Accuracy and Reduced Uncertainty in Resource Measurement Campaigns which made the case for high quality ground measurement during the development stage of utility-scale solar power production.

GroundWork was honored to serve as a co-host of the conference, a role we enthusiastically embraced with determination. We take great pride in being an integral part and active participant in this industry-leading workshop, which sets standards and gathers valuable contributions from so many of our esteemed colleagues.
