| Energy saving and carbon reduction in buildings is the key link for our country to achieve "carbon peak" and "carbon neutral" goals, and the important way to develop high-quality and large-scale application of photovoltaic power generation. Through the collection and collation of relevant literature, this paper systematically analyzes the factors affecting the power supply efficiency of photoelectric buildings, and uses Likert scale to compile and distribute questionnaires. Based on the structural equation model, the data were collected and screened by SPSS22 and AMOS26 software. The data were processed and a model was established to identify the main factors affecting the energy supply efficiency of photovoltaic buildings. The model results show that the first-order indicators that should be paid attention to are module conversion efficiency and mechanical load, whose first-order weight coefficient is 0.254, indicating that the module power attenuation loss and dust occlusion loss are relatively serious in the process of converting light energy into electric energy. The energy conversion efficiency of photovoltaic buildings can be improved by strengthening the control of key factors. The research on the influencing factors of the power supply efficiency of photoelectric buildings is of great significance to achieve the goal of "carbon peak" and "carbon neutrality" |
