Bifacial modules convert light captured on both the front and back sides of a PV module into electrical power. Bifaciality improves PV system energy capture—dramatically in some cases—and rewrites conventional system design rules in interesting ways. In this article we explore the potential benefits of bifacial PV modules and best practices for designing and deploying these systems. We also address challenges to adoption and efforts under way to unlock the full commercial potential of bifacial...
