Project Summary

Solar photovoltaic (PV) panels get dirty, or soiled, which decreases the PV energy yield. PV soiling leads to around $2 billion U.S. dollars lost annually worldwide [1]. In this research, we are exploring the ability to predict PV soiling performance using local air quality data. This research could contribute to solar developer’s creating more accurate energy yield and finance models.
