Analysis of Persistent Soiling Losses: Cooperative Research and Development Final Report CRADA Number: CRD-24-30366

Summary

This report addresses the challenge of persistent soiling on solar panels, which reduces efficiency and is not easily removed by rain. Through the analysis of thousands of microscopic images from hundreds of solar sites in the eastern U.S., researchers discovered that fungal growth, rather than pollen, is the primary biological agent causing these sustained losses. The Cooperative Research and Development Agreement (CRADA) work is completed, with findings leading to ongoing investigations and a pending publication to share these insights.
