Abstract：With the advancement of China's'double carbon'strategy,distributed rooftop photovoltaic systems have been widely applied.Combining typical residential rooftop photovoltaic projects,the key electrical design links are systematically studied,including inverter selection,photovoltaic string design,circuit breaker configuration and cable cross-section selection.Based on the actual project data,the energy-saving and emission reduction effects are analyzed,and the environmental and economic benefits of the design measures are verified.The results show that a reasonable and optimized design scheme can enhance the operational efficiency of the system,reduce power loss,and provide a reference for the standardized electrical design of distributed photovoltaic systems.
