Abstract The single-axis tracked bifacial field at NREL is unique because it incorporates five different technologies of bifacial PV modules with side-to-side monofacial counterparts. We have observed accelerated degradation for various of this early-generation bifacial technologies deployed relative to monofacial counterparts. This project aims to investigate the source of this degradation, and release the investigation approach and findings.
