Welcome & Introduction: Why Are We Here? 1:00 pm
An overview of the workshop will be presented, along with intended outcomes, goals and next steps.
|Welcome and Purpose||Joshua Stein||Sandia National Laboratories|
|Summary of Previous Workshop||Chris Cameron||Independent Consultant|
Module Models (1): Generating Performance Coefficients 1:30 pm
The selection of a module performance algorithm and associated module performance coefficients is a critical step in modeling system performance. These presentations will emphasize the process for deriving performance coefficients from test data.

Thursday, May 2
Solar Resource Data 8:00 am
The expected solar resource at a site is critical to establishing project viability. This session will present methods to reduce project risk by addressing bias and uncertainty in solar resource data.
System Losses and Derates 10:15 am
Estimates of system losses vary greatly among models and modelers. This session will seek to improve our understanding of system losses and the means of modeling them.
|Draft Definitions of System Loss Factors (Note: Both of Geoff’s presentations are merged into a single file)||Geoff Klise||Sandia National Laboratories|
|Quantifying Mismatch Losses in Small Arrays||Sara MacAlpine||University of Colorado, Boulder|
|Calculation of Mismatch Losses due to Shading in PVsyst, v6||André Mermoud||PVsyst|
