|Abstract:||Bifacial PV turned out to be an effective means to reduce the levelized energy cost of PV systems. Many of the advanced solar cell concepts, which are currently implemented into industrial production, are bifacial or allow a comparatively simple adaption to a bifacial layout. An additional rear side contribution to the module energy yield is thus obtained with minor additional cost or even cost neutral. The yearly energy yield is substantially improved by 5-30 %, dependent on location, module´s bifaciality and system design. Lowest LCOE values are achieved with ground mounted PV systems using bifacial modules and optimized installation designs. In most of the cases for desert applications bifacial tracking is the best solution. This article reports on state-of-the-art bifacial PV systems and gives an overview about the relevant components such as modules, sub-constructions, tracking systems and suitable inverters. Special attention is given to the ground reflection and to the energy yield of bifacial systems. In addition, simulation and measurement results concerning the LCOE of bifacial and monofacial systems are presented and compared.|
