“…An extensive analysis to investigate the spectral biasing effects caused by the albedo of 22 common surface materials on seven different PV materials in residential, commercial, and industrial solar PV applications is conducted in the study of Brennan et al [8] The study provided effective albedo for surface material and PV material combinations. Zahid et al [9] focused on the improvement of power generation by placing the reflectors at an optimal angle. Kim et al [10] focused on the impact of nonhomogeneous light falling at the rear side of bifacial panels.…”

The ability of bifacial photovoltaic (PV) to absorb solar radiation on either side increases the energy output. Reflectors increase the albedo and help to increase the performance. Reflectors face discoloration and degradation with time and they increase the overall implementation cost of bifacial PV systems. However, the cost of reflectors can be reduced by using nonbiodegradable waste as reflectors. They also increase the reusability of nonbiodegradable waste materials and reduce their impact on the environment and the cost of reflectors. To make a comprehensive analysis, an investigative approach of energy, exergy, economic, exergoeconomic, enviroeconomic, and energy payback time (6E) analysis is conducted for the bifacial PV module with nonbiodegradable waste, such as polyvinyl chloride (PVC) flex, polystyrene foam, and aluminum foil as reflectors in this study. The 6E analysis includes the analysis of energy, exergy, economic, exergoeconomic, enviroeconomic, and energy payback time factors. The analysis results indicate that the PVC flex as a reflector enhances the bifacial PV performance better compared to polystyrene foam and aluminum foil. The average power, average energy efficiency, and average exergy efficiency of bifacial PV with PVC flex reflector observed during the study are 224 W, 27%, and 31%, respectively. The use of nonbiodegradable waste also has a positive impact on the environment and economy.

In the context of offshore floating photovoltaic systems (FPVs), this paper explores the use of bifacial photovoltaic modules installed in the vertical position. The energy harvested from the rear face of vertically configured bifacial PV modules compensates for the reduced production at the front face of the module, and this demonstrates the potential of bifacial technology for offshore applications. By comparison, most existing horizontally tilted bifacial FPV systems gain only a small benefit in production from the rear face of the module due to the minimum radiation received, and what also must be taken into consideration is the negative effect of significant soiling owing to the low tilt angle of the PV modules. Hence, to overcome these drawbacks, we have developed the innovative “PVSail” concept, which explores the deployment of vertical FPV systems on floats, buoys, or poles/minipiles. Floating vertical bifacial PV systems (VBPVs) have huge potential to harness all the energy generation capabilities enhance by reflected light, especially from snow‐covered surfaces in northern regions. Our analysis considers a patented mooring and vertical PV system that allows the VBPV structure to align with the prevailing wind direction to shed wind loads, and our numerical analysis explores the potential of VBPV applied to Catania in Italy and Nigg Bay in the United Kingdom. Our analysis study has revealed that across an azimuth angle range (0°–180°), vertical bifacial modules experience roughly a 9% decrease in energy yield at Catania and about a 5% energy yield gain in higher latitude regions like Nigg Bay. Additionally, increasing the latitude of the installation location of VBPV reduces the energy yield sensitivity to the orientation, that is, azimuth angle. The PVSail concept opens the door to novel deployment possibilities in offshore renewable energy projects.
