Bifacial photovoltaic technology has completed its transition from an emerging innovation to a mainstream solution within the solar industry. Bifacial modules are no longer regarded as a niche product and are now widely deployed, representing the predominant choice in most utility scale, commercial and many other solar projects. The change is being driven by the ability of bifacial PV systems to significantly increase energy yield and reduce levelized cost of energy (LCOE). Double-glass bifacial modules, in particular, offer durability, long-term stability, and enhanced performance in diverse environmental conditions.
