Abstract

In this study, a thermoelectric coupling model was established for the facade BIPV system, and a simulation program was written using the Matlab platform to analyze the power generation patterns of the BIPV system in different regions. The research first introduces the working principle of the facade BIPV system, and constructs a thermoelectric coupling model based on the power generation and heat transfer processes. Using the facade BIPV experimental platform with six moduls rated at 385 W each Xi 'an, Shaanxi, an error analysis was conducted between the simulation data and the experimental data. The RMSE between the predicted value of the model power and the experimental value is 1.0357 W, the MAE is 0.7117 W, and the RE is 2.7 %. By simulating the power generation data in different regions, the simulation results show that the areas with abundant solar energy resources （severe cold and mild areas） have higher annual total power generation. Although the solar radiation conditions in severe cold areas are limited, power generation on the south facade is outstanding in winter. In addition, in hot summer and cold winter, hot summer and warm winter and mild areas, the difference in power generation in each orientation is small, and it is suitable to flexibly adjust the configuration in the east, west and south directions according to the building layout, so as to fully tap the power generation potential of each orientation.
