Compared with monofacial photovoltaics, bifacial photovoltaic modules can absorb the irradiance on both sides, thereby obtaining more electricity revenue, which can meet more demands. In order to further improve the electrical efficiency of bifacial photovoltaics, this paper proposes a bifacial photovoltaic module with adjustable inclination for simulation and experimental research, which can be well combined with architecture. Under the conditions of different inclination, orientations and heights, the output performance of the bifacial photovoltaic module is analyzed. Under the best inclination, the annual electrical energy of bifacial photovoltaic is about 9.4% higher than that of monofacial photovoltaics. When the spacing between the bifacial photovoltaic and the wall is 1-1.5 times the size of the photovoltaic, the electrical energy will increase the most. Considering the influence of wall color on bifacial photovoltaic performance, the photovoltaic electrical energy under the white wall can reach up to 35% higher than that with respect to the concrete color (dark grey).
