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.
