To meet increasing demand for sustainable and reliable energy solutions, the bifacial solar photovoltaics (PV) technology has the capacity to provide additional energy generation for installed power systems due to its ability to utilize both front irradiance and ground reflected light. Back reflectors have been designed to increase the power of the cell found on the rear side of the module by utilizing the intercell light passing through the module to increase the incident irradiance. The effect of back reflectors on the overall energy output of bifacial PV modules using six different profiles placed at varied distances from the plane of array (POA) is examined. This work demonstrates that a significant energy gain and cost reduction in the array structures can be achieved using back reflectors compared to conventional bifacial arrays.
