Abstract：Taking a photovoltaic building in Xining City as the research object,studying the influence of the interaction among the installation inclination angle,installation position and type of photovoltaic modules on the total power generation and return on investment of the photovoltaic system based on Grasshopper,and clarifying the optimization direction under different demand scenarios,and putting forward differentiated configuration suggestions.The results show that the installation location and type of photovoltaic modules have a significant correlation with the total power generation and return on investment of the photovoltaic system,while the installation inclination angle has no significant correlation with the total power generation and return on investment.The combination with the largest total power generation is'roof+east and west walls+south wall,all using type two photovoltaic modules',with a total power generation of 7 938 664.33 kWh.The combination with the highest return on investment is'roof,all using type one photovoltaic modules',with a return on investment of 333.83%.
