Performance analysis and comparison between bifacial and monofacial solar photovoltaic at various ground albedo conditions

This paper analyses and compares the performance between a bifacial monofacial PV system based on tests conducted at Heriot-Watt University, UK. The module's was observed different ground reflective surfaces: concrete, white tiles, soil, pebbles. rear side irradiance energy gains are analysed. power output is examined for sunny cloudy days, yearly mapping shown. Correlation studies performed, empirical model developed (i) clearness index gain: (ii) gain gain; (iii) total output. Based annual analysis, highest range found pebbles tiles surface (>30 % gain) lowest soil within 5 %–10 >20 %. Regardless of surface, probability low that more than 30 Finally, case study discussed to perform sensitivity analysis project's Levelized cost electricity (LCOE). shows by using an enhanced albedo LCOE project can be reduced 7.15p/kWh. results show consistency with simulations ran in PVSyst locations across UK reported worldwide.
