Abstract: This research focuses on optimizing the entire process management of distributed photovoltaic power generation projects, aiming to enhance approval efficiency, construction safety and economic sustainability by systematically analyzing the pain points in the full process management of distributed photovoltaic power generation projects and proposing standardized solutions, providing a replicable optimization model for the high-quality development of the industry. Firstly, it analyzes the project construction process and key node tasks of distributed photovoltaic power generation projects, including the early-stage assessment, approval and filing, engineering implementation and grid connection operation. Secondly, it dissects the main problems in the management of distributed photovoltaic power generation projects from the aspects of project approval, engineering construction safety management, financial balance and sustainable development, provides targeted solutions. Finally, taking a photovoltaic power generation project as a case, it shares the full-process management experience of the project in planning and approval management, engineering construction safety management, and financial balance and project sustainability. It proposes a three-in-one optimization solution of "pre-positioned parallel approval of technology -intelligent control of construction safety -financial balance and sustainability", providing an empirical solution path to break through the bottlenecks of difficult policy implementation, high construction risks and weak economic sustainability in the
